Cannabis Improved His Life After the Army, but Driving Laws Stand in the Way of His Freedom

Cody is sharing his experience as part of our “Personal Stories” series, inviting medicinal cannabis patients to share with the community how drug driving laws are impacting their quality of life. If you’d like to share your story, please email us at hello@drivechangemc.com.au


Hi, my name is Cody. I’m 30 years old living with my partner and two beautiful kids in the northern suburbs of Adelaide. I have been a medical cannabis patient since April 2021, but my journey began around 7 years ago.

In 2013 whilst serving in the Royal Australian Army, I suffered an acute knee injury that transformed into chronic pain. I have had multiple surgeries and countless hours of physiotherapy, none of which solved the problem. While I was dealing with this chronic pain, mental health issues began to develop. As a result, I was medically discharged in 2015. I had served 6 1/2 years.

Cody relies on a driver’s licence to keep his job and provide for his family. The drug driving laws pose a threat to his livelihood and his wellbeing.

Somewhere along the way, I had also developed a terrible relationship with alcohol, abusing it to numb both my body and mind. This lasted five years. I’m sober now, having not touched a drop since December 2020, but I attribute much of that success to my amazing family and psychiatrist.

In the past, I sought conventional drugs to cope with my struggles. Antidepressants and strong opioid-based medications have been regular medications for me since 2014. As time progressed, I began taking benzodiazepines and sleep aid medication.

In my experience taking these drugs over the years, I’ve had a handful of unintentional overdose experiences. It’s very concerning how easily this can happen. This ranged from skin itches and rashes to becoming violently ill and losing consciousness.

It would be safe to say that I’ve had my fair share of traditional prescription medication.

In an attempt to relieve me of my dependence on these troublesome drugs, I obtained a legal prescription for cannabis. It quickly became clear that there were benefits of cannabis on both my physical and mental state. I had no adverse effects from cannabis, leaving me stumped as to why medicinal cannabis wasn’t more widely accepted.

Starting to medicate with cannabis has been the best medical choice I have ever made. At least 90% of my medication is cannabis. As a result, my dependence on both opioids and benzodiazepines has plummeted.

However, the biggest problem I have with medical cannabis is the unfair and discriminatory drug driving laws across the country, specifically in my current state of South Australia.

Like a lot of people, I work and need a licence to do so. However, every time I get behind the wheel I run the risk of testing positive for THC at a roadside drug test, even several hours after the impairing effects have worn off.

It makes you feel like a bit of a criminal. Unfortunately, this is a common feeling amongst the medical cannabis patient community.

Medicinal cannabis patients shouldn’t have to choose between medicating or keeping a driver’s license and job. If someone is prescribed medicinal cannabis and they’re not driving impaired then they should not be guilty of an offence.

These laws need to change immediately, the current legislation is discriminatory, outdated, and maintained purely through ignorance.

I have seen and also personally experienced such a positive outcome that medical cannabis has to offer, I beg everyone involved in the legislation of this: please reform these unfair laws now.

One Size Does Not Fit All: Mick Palmer on the Need for Fit-For-Purpose Driving Laws in Australia

Read time: 3 minutes

This article is written by Drive Change ambassador and former Commission of the Australian Federal Police, Mick Palmer. Below, he shares his take on where the laws need improvement to protect medicinal cannabis patients and the community on the road.


There is a clear and well-understood correlation between impaired driving and road safety. Australia’s road toll is of broad community concern, and the Government’s effective policies–like the .05 drink driving legislation and speed cameras– should be applauded. However, Australia’s ‘zero-tolerance’ drug driving policy creates trouble for both patients and police. 

“Fit-for-Purpose”

The government has already allowed for doctor-approved access to medicinal cannabis. This comes in response to the ever-growing scientific evidence, in addition to anecdotal evidence, that medicinal cannabis provides relief for people experiencing genuine pain and suffering due to a range of health issues, including terminal illness.

The government’s recognition of this evidence provides a step toward relief for thousands of Australians. However, for the legality of medicinal cannabis to fully operate as intended, the roadside drug testing protocol urgently requires amendment. 

I am not suggesting impaired driving laws should be weakened, but rather that they are updated to fit-for-purpose and aimed at achieving intended outcomes. 

To become fit-for-purpose, retain credibility, and operate fairly, driving laws must be aimed at dealing with impaired driving. Until this happens, many law-abiding Australians suffering from illness and often extreme pain will continue to experience legal and physical distress as a direct result of the discriminatory drug driving laws. 

“Police Leniency”

Likewise, police have a clear responsibility to effectively manage and apply the legislation in the community interest. The truth is that police exercise considerable compassionate discretion in their enforcement of drug driving laws every day. This is, in part, due to the driving laws being unfit-for-purpose and in need of review and amendment, or repeal.

The role of the police is to enforce laws, not make them. It is certainly a recipe for inconsistency to expect the police to cure legislative deficiencies by making personal judgments on patients. 

Furthermore, if police are screening for medicinal cannabis use but not for impairment, the laws are unfit-for-purpose and end up punishing people already coping with a terminal illness or serious pain.

Medicinal cannabis patients should not need to rely on the favourable exercise of discretion by police to escape punishment. It is up to Governments to have the courage and decency to legislate the necessary changes.

“Necessary Changes”

If there is any chance that medicinal cannabis can help people with terminal illness or serious pain, to lessen their pain and suffering and improve their quality of life, we should, as an educated and compassionate society, do all that is reasonably possible to facilitate access. 

The fact that these current drug driving laws exist is sufficient for many patients who qualify for medicinal cannabis treatment to decide not to take their medication. 

Some of these patients need to drive their motor vehicles as a matter of daily necessity. Sufferers should not be forced into situations where they may end up breaking the law to gain relief. Surely this is not the government’s intention.

The reality of current roadside testing is that they are not only discriminatory, but also invariably lead to further distress, fear, and embarrassment for the patients.

The resulting pain and suffering achieve the exact opposite of the intention of Governments in allowing legal access to medicinal cannabis in the first place. I am personally confident that this also is not the intention.

The facts speak for themselves. There is a better way to uphold law and road safety. We must be prepared to explore the options. 

As an example, Norway has successfully been assessing drug levels in driver’s systems for many years. This surely is far preferable to the continuation of a “zero-tolerance” approach that we have here, which can only be beaten by judicial discretion.

The current medicinal cannabis drug testing laws need to be subject to urgent review. By amending the laws, we move to ensure they operate fairly and without discrimination while continuing to achieve the intended outcome of controlling impaired and potentially dangerous driving.

Scientific Research: Cannabis Vs Other Drugs & Driving

Read time: 2.5 Min

Recently I co-authored an article called Cannabis & Driving, which was published in the Australian Journal of General Practice. The report reviewed the scientific evidence regarding cannabis and driving impairment. It also discusses the legal issues affecting patients and physicians.

The findings lead us to conclude that medicinal cannabis should be treated the same way we treat all other potentially impairing medications.

I’ve written this short article to summarise the findings for Drive Change, supporters of the campaign, and those fighting for equal rights for medicinal cannabis patients.

THC vs CBD

THC, put simply, is the part of cannabis that can get you stoned. It is used to treat a range of conditions, including chronic pain and chemotherapy-induced nausea and vomiting. 

On the other hand, CBD is non-psychoactive, which means that it doesn’t get you stoned. It is used to treat anxiety, psychosis, and some neurological disorders.  

When combined with THC, CBD may help reduce some of the adverse side effects of THC (e.g., anxiety and paranoia). However, this does not mean that CBD decreases the impairing effects of THC.

Cannabis and Driving

Scientific research shows that cannabis can impair driving ability and certain cognitive functions such as divided attention and working memory. These effects, however, are relatively mild and disappear as the body metabolises THC. 

Comparing cannabis and other drugs

When it comes to driving, current evidence indicates that a driver who tests positive for cannabis is approximately 1.1-1.4 times more likely to be involved in a crash relative to a sober driver. 

To put this into perspective, a driver with a legal blood alcohol concentration of .05 is approximately 1.3-1.8 times more likely to be involved in a crash relative to a sober driver. 

And a driver who tests positive for benzodiazepines (e.g., Valium) is approximately 1.2-2.3 times more likely to be involved in a crash relative to a sober driver.

It is important to remember that these are just estimates; these numbers could be higher or lower in reality. In a recent study of ours that looked at real-world driving performance, participants who had vaporised cannabis tended to have a very similar level of impairment to what we would expect to see in a driver with a BAC of .05. 

There is no evidence that CBD impairs driving at all.

What About Medical Cannabis?

Almost all this evidence comes from studies involving healthy volunteers who use cannabis occasionally. We know that people who use cannabis more frequently (e.g., daily) show less impairment than occasional users when given the same dose of THC due to the development of tolerance. 

Patients consuming cannabis daily and at doses that are therapeutic rather than intoxicating may be even less impaired. This is especially true if their cannabis use relieves an underlying condition that can impair driving, such as chronic pain. Research is currently underway to test this hypothesis. 

Conclusion

Overall, cannabis (and THC, specifically) appears to have a relatively minor impact on driving performance. 

However, it can produce significant impairment in certain situations, such as when combined with alcohol and when used by people who are unfamiliar with its effects. 

Patients who are using medical cannabis should be aware of these considerations and remember that it is illegal to drive if you have any detectable amount of THC in your system. In addition, you may still test positive for cannabis even if you are not impaired. And, having a valid prescription for medical cannabis does not exempt you from current roadside drug testing laws.

Drive Change Submission to NTC: Assessing Fitness to Drive

Read time: 1 Min

On the 11th of June 2021, the Drive Change Team responded to the National Transport Commission’s Assessment of Fitness To Drive Interim Report public consultation.

We were lucky to have a majority of our Ambassadors, Supporters and Friends sign on to the submission, which we believe shows great support for ending discrimination toward medicinal cannabis patients. Here are the organisations and individuals who supported our submission:

Drive Change NTC submission friends ambassadors and supporters

Submission Summary

The proposed recommendations state that healthcare practitioners are to determine a medicinal cannabis patient’s ‘fitness to drive’. This recommendation aligns with the current guidelines for all other prescribed potentially impairing medications such as opioid analgesics and benzodiazepines.

It does not change the liability of the healthcare professional from the current state. 

And, like all other medications, the doctor makes the initial assessment, but it is the patient’s responsibility not to drive whilst impaired.

The Drive Change Team, and all parties involved in the submission, agreed with the proposed recommendations. Passing these guidelines and amendments would be seen as a federal recommendation to create equal rights for medical cannabis patients.

Thank you to all of our Ambassadors, Supporters and Friends for their continued support toward making changes to these discriminatory drug driving laws.

An update on the VIC Medicinal Cannabis Patients and Driving Working Group

The Medicinal Cannabis Patients and Driving Working Group report has been in government hands for a few months. I am continuing to try and find the solution that will enable medicinal cannabis patients to drive when they are not impaired.

Currently, medicinal cannabis patients are effectively prohibited from driving due to the medication that they take, not because they are impaired. This is patently unfair and discriminatory.

For many patients, medicinal cannabis has enabled them to stop or reduce their use of opioids and benzodiazepines, which can be far more impairing. Sadly, we hear about patients who have gone back to these addictive and impairing medicines. They do this because they can continue to drive while taking them, despite getting better results and pain relief from medicinal cannabis.

Doctors advise patients about the risks of all medicines that may impair their ability to drive safely. But for patients taking medicinal cannabis, doctors are required to inform them that they cannot drive at all regardless of whether they are impaired or not. This is just a travesty when many of them are feeling alert and well because of this medicine.

I believe that we can provide a simple exemption for medicinal cannabis patients who have a valid prescription and sound doctor advice. As far as I am aware there is not a single case of a medicinal cannabis patient being in a car accident in Victoria in the five years that this medicine has been available.

I also made a note of the following commitment from Minister Leane recorded in Hansard:

“I want to restate our government’s commitment to Ms Patten that we are really keen to work with her on this particular issue. We are going to work with Ms Patten on the outcome to ensure people are not disadvantaged by taking their medication.”

I can assure you of my ongoing commitment to Victorian doctors, medicinal cannabis providers and, most importantly patients, that we are addressing this discriminatory and unfair situation.

The Truth: Roadside Drug Testing Doesn’t Reduce Road Trauma

At Drive Change, we lobby to exclude medicinal cannabis users from the draconian drug driving detection laws. There are numerous reasons these laws are just plain wrong. But, one of the arguments we keep coming up against is road safety. Opponents of law change are adamant that these laws are designed to improve road safety. 

The fact is – our current drug driving laws do not improve road safety. 

This blog analyses the current drug driving laws and road safety and provides evidence for why these laws must change.

Correlation and Causation: The Basics

It is stating the bleeding obvious that there is a distinction between correlation and causation. 

Just because two things occur does not mean that one causes the other. There are some marvellous websites that exemplify the difference between causation and correlation. My favourite one contrasts the purchase of cheese per capita and the number of people who die from becoming tangled in their bedsheets.

Stunningly, this correlation can be mapped by double lined graphs for decades. These results certainly do not prove that eating cheese causes death in this manner or that death in this manner leads to eating more cheese by the bereaved. It is possible, of course, that these two arguments are true – but it is more likely that there are other factors at play. In that case, the old demon of coincidence. 

Yet this classic and basic error is repeatedly made in drug detection driving and road trauma. 

Just because individuals who died in car accidents had a drug in their system does not mean the drug was the main cause of the accident, particularly relating to cannabis medicine.

Examples of Over-Egging the Pudding

Every time someone mentions law reform, someone else will trot out the tired old argument that the presence of illicit drugs in your system leads to more deaths and injury on the road. 

For example, in opposing drug driving law reform in NSW in 2020, Scott Farlow MLC stated in parliament:

“NSW crash data indicates that since 2014 there has been a 7% increase in the number of fatalities and serious crashes directly attributed to the presence of an illicit drug.”

The media, even responsible mastheads, often do not help. For example, there is this headline from the Sydney Morning Herald, also in 2020:

“On Ice or Doped Out – Drug driving deaths rise across Australia.”

This article boldly declares that drugs contribute to one in five deaths in New South Wales and cites research by Dr Mathew Baldock (more on this shortly).

“Driving with drugs in your system is not only illegal, it’s extremely dangerous and puts your life and the lives of all other road users at risk.”

Unfounded statement by the Director of Road Safety in NSW

And all this “research” leads to fiction-based declarations like this by police, politicians and, in this case, the Director of Road Safety in NSW.

Research Findings: No Causation

In NSW, the research shows that in the nine years from 2010 to 2018, 21 per cent (384) of the 1818 drivers or riders who died on NSW roads had an illicit drug in their system. In Baldock’s study, it was over 15%, with around 9% amphetamines and 6% THC. There are other similar studies with results in that range. 

However, nowhere in the actual published research is there anything like proof of causation. 

In other words, there is nothing to suggest that even just one of those deaths was caused by the presence of drugs, a classic example of confusing correlation with causation.   

A careful analysis of Baldock

In South Australia, as in other states, those killed in road accidents are subject to mandatory blood tests. The cut-off level for THC is two nanograms. In the Baldock study, they tabulated the results of this and found that around 6% of those who died had a detectable level of cannabis in their system. 

And from this, the authors and others have claimed a causative connection – THC presence leads to deaths. To those blessed with the knowledge of correlation/causation errors, the problems with this argument become immediately apparent. 

To show causation, one would need first to prove that at this level, drivers were adversely affected by the THC in their system. Given that cannabis can be detected for up to six days in the blood, that would be impossible.  

Second, there would need to be evidence that the driver was at fault. There is no analysis of this in the research, and many of those may have been the innocent driver. We’ll never know. 

Third, there would need to be research showing that 6% with THC presence is higher than the norm amongst the population profile of those who died. Research shows that around 30% of those aged 18 to 24 have recently used an illicit drug, with cannabis use by far the most common.

It is entirely possible that the 6% figure is an underrepresentation. Of course, that does not mean that cannabis consumption makes drivers safer either – that would be confusing cheese and bed strangulation as well.

Fourth, to rely on this research to make the causation argument, one would hope to find a single statement linking the presence and the deaths within the published study itself. There is none. And that is because the authors would not want to be the laughing stock of their peers for making a research 101 error. 

Fifth, there is not one iota of evidence that a single driver was driving while taking medication under a prescription. The demographic profile of those with prescriptions for cannabis containing THC is markedly different from those who are most commonly involved in fatal motor vehicle incidents.

According to TGA, the average patient is about 50 years old, female and has access to private funds for expensive medicines. Further, they are actively seeking to minimise the psychoactive effects – they are not using a bong at a party, getting in a car and having a collision on the way home. 

Finally, there is no evidence that these laws have reduced the road toll at all in any jurisdiction in Australia. When random breath testing for alcohol, seatbelts, speed limits and airbags were introduced, there was a marked decline in the road toll.

Although there are over 500,000 drug driving detection tests per year, there’s still no evidence the roads are safer due to random roadside testing. 

Conclusion

There is no correlation between the presence of THC in saliva and impairment. More importantly, there is no evidence that driving with a detectable level of THC increases the risk of road trauma. 

Efforts to link the two exemplify a classic case of confusing correlation with causation. This mischief is not just inaccuracy; it serves to provide a significant hurdle to reforming laws that unjustly and unjustifiably discriminate against medicinal cannabis users.

THC improved my life; now, these unjust laws are hurting me.

This is the story of Deborah. Deborah is a mum and an active, productive member of society. She has been suffering from chronic pain for four years. Chronic pain changed her life:

Chronic Pain affected the way I exercise and socialise. But the health aspect it had the most significant impact on was my mental health. 

Deborah A

My pain

For me, chronic pain occurs as a 24/7 headache. When it flares up, it sends pins and needles and numbness to other parts of my body. Headaches can range from mild to severe, non-stop. I have seen dozens of health practitioners in different medical specialities over the years. While some have helped me understand and manage the pain – I’d never found relief.

CBD + THC = Relief

At the start of 2020, I decided to see a doctor for medicinal cannabis treatment. I was approved and started with CBD isolate for two months. CBD isolate is a CBD only product – it doesn’t contain any other cannabinoids or chemicals from the plant. It did not have the desired effect. 

My doctor suggested I try a product with a THC component. After a few weeks, I had pain relief for the first time. At the time, I was working from home due to COVID and wasn’t driving. So, there weren’t any issues with taking THC. 

The impact of discriminatory laws

I could only use the THC for about two months as a trial and then had to stop as I needed to drive again. My daughter was on her final year of L plates, and I wanted (and needed) to drive with her. 

My headaches came back, and my quality of life diminished again. 

In early April 2020, my daughter received her license. I can once again get support from my family to drive me around when needed.

I’ve been able to start my cannabis prescription again, and within one week, I’m already feeling the amazing benefits. 

When I’m feeling better, I can’t drive. When I’m feeling unwell, I can. Because I need this medication, I cannot legally drive. The challenge is that I MUST drive. Not driving has an enormous impact on my work life, my hobbies, and my social life. I have no interest in driving impaired, just healthy.

I’m looking forward to seeing the rules change to allow all medicinal cannabis patients to drive when unimpaired. We need a defence for presence so that patients can drive without being fearful of testing positive for THC. 

I am supportive of the fight for Change.

Drive Change honoured to have presented to AMCA board on 4/20

The current state of Change

It has been three months since the Drive Change campaign held its first Supporters & Stakeholder meeting. At the meeting, the Drive Change team presented why this campaign is crucial for future and existing patients. The team also asked both industry (product producers, importers and suppliers and the industry bodies to provide support.  

Since December, Drive Change has gained massive traction and has raised seed funding of roughly $11,500. With those funds, the team has been able to spend time working on initiatives that have led to:

  • Partnership with Tammy Franks MLC from South Australia.
  • Expanded our social presence.
  • Reaching over 35,000 people via Drive Change channels in the last 30 days.
  • Helping individuals disadvantaged by these laws to find legal counsel.
  • And sharing patient stories with decision makers.

These are all significant steps toward making some long overdue legislative change. 

Presenting to the AMCA

On Tuesday 20th April (yes, 4/20), David Heilpern and Tom Brown, members of the Drive Change Team, presented to the Australian Medicinal Cannabis Association (AMCA) Board. The AMCA is one of two industry bodies. The AMCA is the patient focussed industry body. The AMCA has supported the Drive Change campaign from the beginning and has now given us the opportunity to tell them what we need to work for Australian patients. 

It was an honour for the Drive Change team to speak to such an influential group. Readers of this may not know, but Lucy Haslam is the chair of the AMCA. Lucy was a driving force behind the legalisation of Medicinal Cannabis in Australia. Lucy has been an ambassador for change for years now, and we are excited to have her support and backing to help fight these injustices. 

Uniting industry, patients and government

We were excited for the chance to encourage AMCA’s industry members to get behind the campaign. Drive Change is an opportunity for the industry to unite with one message and to join others in being a voice for patients, Australia-wide. Drive Change is an excellent opportunity for a coordinated and collaborative campaign that can bring industry, patients and political figures together for change.

Drive Change is an excellent opportunity for a coordinated and collaborative campaign that brings industry bodies such as AMCA and the Medicinal Cannabis Industry Association (MCIA) and patients and political figures together. 

drive change discrimination - medical cannabis no defence for presence

Our current discriminatory laws depict individuals who need a better quality of life as criminals. The laws are destroying the lives of patients taking a medication that their healthcare practitioners have prescribed. 

We believe that together we are stronger. Together we can make a Change.

A Challenge For Change

Drive Change is a non-profit organisation. To date, the Drive Change campaign has raised about $11,500 that has been put toward changing the current laws for patients.

breakdown of $11500 raised to date

To date we’ve spent most of that money on campaign setup. Now we can shift our focus to Advocacy and marketing the Drive Change campaign.

Harm Reduction Australia provided a startup fund of $5,000.

Patients – the individuals we’re working for have donated about $1500.

In an industry of over 100 companies – only 5 of those companies have donated for a total of approximately $5,000. It is our hope that all companies will support and donate to this important campaign for patients.

financial supporters of drive change
Supporters as of 4/20/2021

With industry bodies like the AMCA holding membership of all types of cannabis industry stakeholders, we have been generously supported by their Board to help us raise funds. The AMCA membership is made up of over 100 companies and individuals, all of who have some stake in the cannabis industry that is – patients.

help fund change 35000 change challenge drive change

We asked the AMCA to help us raise $35,000 tax-deductible dollars from its members to help change laws that will benefit medicinal cannabis patients. This is our Challenge for Change.

If we can raise $35,000 from the AMCA members and $35,000 from the MCIA members – we should have enough funds to run Drive Change for a long enough period to make a real difference.

Conclusion

The industry must do better. The industry associations have the ear of the industry. The industry and these organisations have the ear of the government – that’s what big dollars do.

Patients need the entire industry to start financially supporting advocacy efforts or, to put it bluntly, start putting their money where their mouths are. 

The industry is made up of manufacturers, licensed producers, clinics, importers, exporters – any company that makes money from patients or is here to serve patients. We need your help. Most importantly, patients need your help. 

Without a coordinated effort to Change this outdated and unjust law, patients will continue to suffer and be punished.

For patients reading this – we need you to pressure both government and industry bodies to get behind the Drive Change movement.

We look forward to keeping all of the Drive Change supporters up to date on our progress and the outcome of all of our future efforts.

Once again, we’d like to thank the AMCA and the AMCA board for allowing us to present Drive Change to the board and its members.

8 Problems With Current Drug Driving Laws & Medicinal Cannabis

Read time: 3.4 Min

As someone working in the cannabis space, I constantly see people asking questions about their prescription cannabis and driving or raising their concerns about what could happen to them or how cannabis has changed their lives. Here are two quotes that I think sum up both the benefits of cannabis (for some) and the stupidity of our current laws regarding medicinal cannabis and driving.

I’m a legal patient, and I’m too anxious to drive. Even if it’s been a couple of days or longer, I’m still worried that because of my medical cannabis use, I could lose my license or, worse – go to prison for using a medicine that means I’m not bedridden and actually have the choice to go somewhere.

But, because of the law, I can’t drive…it’s the worst catch 22 ever. I’m finally able to go somewhere and do things, but I can’t.

I’m currently unemployed and can’t get employment if I can’t drive.

It’s horrible… if I go back to pharmaceuticals (Oxycontin, Lyrica, Valium or even Subutex), I would be allowed to drive – but I’d go back to being incapacitated and suicidal.

Anonymous Medicinal Cannabis Patient

Lyrica is one of the worst drugs I’ve ever taken. I just wanted to kill myself the whole time. Now I’m taking medical cannabis, and my life has changed for the better. The fact they test for presence and not for impairment shows how unjust the law is.

Steve, NSW

These prescription drugs that make people suicidal are the medications that our doctors are so comfortable prescribing and often preferable to (over cannabis).

It’s not all black and white

Unfortunately, our current laws are pretty black and white.

  • if you have cannabis in your system – defined as THC present in your mouth – you cannot legally drive

Fun fact: Tassie is the only location in Australia with a medical defence (but it’s unclear whether you needed to get it prescribed via the tassie system – which is currently almost impossible – to change on July 1 when all GPs in Tassie will be able to prescribe).

What’s not black and white is how long cannabis stays in your system, particularly in your saliva. It’s also unclear why the government continues to test for presence when patients can beat the system if they really want to and when the tests we use are incredibly inaccurate.

THC only gets into saliva in the first place due to contamination of the oral cavity when you consume cannabis. So, it’s only when you use cannabis by smoking, vaporisation, eating or via any other way that it comes into direct contact with your mouth that you’ll actually end up with THC in your saliva.

Tom Arkell, The Lambert Initiative For Cannabinoid Therapeutics

Why the system is just wrong

There are several problems with this current system. Here are eight undeniable reasons that the system is wrong, broken and discriminatory:

  1. Presence doesn’t mean impairment.
  2. The time THC can stay in your system is different for each person.
  3. No matter what anyone tells you about how long to wait – they aren’t 100% correct (refer to point 2).
  4. THC can be present in your mouth via transfers (being around someone who is smoking/vaping and theoretically even kissing someone after they’ve consumed cannabis.
  5. No one knows how much THC in any one medication will show up on a roadside swab. For example, the over the counter CBD is allowed to have up to 1% – that may actually show up on a saliva test.
  6. The tests can be beaten if you put an oil or activated flower in a capsule (unless you burp it up in which case it might be in your mouth).
  7. The roadside swabs regularly give false positives and false negatives.
  8. Legally prescribed medical cannabis is the only prescription medication without a legal defence for presence (when not impaired). Discrimination.

So, if you take a medication with any THC, then it’s really up to you to decide whether or not you ‘risk’ it. If you do get caught, you can lose your license. However, if you get caught and are not impaired, make sure you stay calm and ask the officer (at a strategic time) if they think you’re impaired and ask for an impairment test. 

And, then, as long as you’re not impaired, please reach out to the Drive Change team and tell us your story – someone may be able to help you out.

SA Greens MLC Tammy Franks Joins The Drive Change Movement

Read time: 1.5 Min Read

A big win for medicinal cannabis patients in SA and the Drive Change campaign! The current drug driving laws are discriminatory toward medical cannabis patients. The Drive Change campaign was started to help create driving law reform that’s fair, equal, and improves public health. We’re honoured to have SA Greens MLC Tammy Franks as a supporter and ambassador for Drive Change.

About SA Greens MLC Tammy Franks

Tammy Franks was elected in 2010.  ‘Driven’ for more than a decade, Tammy has taken-on countless issues and continues to advocate tirelessly for people and the planet.  

Tammy’s determined work enabled the passage of the SA Industrial Hemp Act 2017 in 2017, and in parallel, her compassionate advocacy for better and more affordable access to medicinal cannabis for patients continues. 

Recognising that whilst legal to be prescribed Medicinal Cannabis, the State’s drug driving laws are discriminatory. 

“Patients should not have to choose between medicine or mobility.” Tammy is honoured to be associated The Cannabis Law Reform Alliance to #DriveChange

The Road Traffic (Medicinal Cannabis) Amendment Bill 2021

In February 2021, Ms Franks introduced The Road Traffic (Medicinal Cannabis) Amendment Bill 2021 in South Australia. The goal of the Bill:

To create drug driving law reform that’s fair, equal, and improves public health.

As quoted from Ms Franks website:

“The Bill provides for a complete defence against the charge of driving with the detectable presence of THC in oral fluid or blood where a person has a valid doctor’s prescription for a medicinal cannabis product containing THC and that product has been administered as directed. The Bill also makes the defence available for persons participating in medicinal cannabis clinical trials, removing a major hurdle for the advancement of cannabinoid science. The defence is not available in any circumstances involving dangerous or reckless driving or in any matter where the police can establish driver impairment.”
