Patients who are using cannabis-based medicines that contain delta-9-tetrahydrocannabinol (THC) should avoid driving as it remains illegal.
This is because THC can impair essential cognitive and motor functions required for safe driving, including attention, judgment, memory, vision, and coordination.
Those taking cannabidiol (CBD)-only medicines are legally allowed to drive, provided they are not impaired.
However, since CBD can cause side effects such as drowsiness, fatigue, and lowered blood pressure, patients should consult their doctor to assess any potential risks before driving.
NSW Health has a fact sheet on driving for patients prescribed medicinal cannabis.
