Over 18 months, researchers will conduct controlled trials in Melbourne to simulate real-world driving conditions.

These tests will assess how THC—the psychoactive compound in cannabis— affects reaction time, decision-making and vehicle control. The findings will help shape evidence-based regulations, balancing public safety and patient rights in Victoria and beyond.

Tackling a legal and medical dilemma 

Victoria’s zero-tolerance THC driving laws pose challenges for medical cannabis users. THC can linger in the body long after its psychoactive effects subside, forcing patients to potentially risk legal penalties while under treatment. With medical cannabis prescriptions in Victoria soaring by 700per cent over two years, science-driven policies are urgently needed.

Shaping the future of policy

Led by ��õ������’s Drugs and Driving Research Unit, the study focuses on experienced medical cannabis users,  reflecting real-world scenarios. Participants will undergo pre- and post-driving evaluations, completing tasks like braking, steering and reacting to obstacles.

Professor Luke Downey, the project lead, underscores its importance:

“Our findings could help shape policies that protect public safety and patient rights.”

If the study shows medical cannabis use does not impair driving, it could set a global precedent for fair THC driving laws. ��õ������ is once again proving its leadership in addressing complex societal challenges through innovation and tech-enabled solutions.
