The CBDrive trial

We are currently looking for healthy individuals to participate in our trial investigating the effect of cannabidiol (CBD), a non-intoxicating cannabis constituent, on simulated car driving performance.

Participants will need to attend the Woolcock Institute of Medical Research (Glebe, Sydney) to complete an initial medical screen and four research sessions (approx. 5-6 h duration). The research sessions can be scheduled at your convenience but must begin between in the morning. All participants will be reimbursed for their time ($480) and the cost of transportation to and from the study site.

Ethics approval number: 2019/474.


You may be eligible to participate in this study if you:

  • You may be eligible if you are: 
    • Between 18 and 65 years old; 
    • Have held a full (unrestricted) Australian drivers licence for at least 1 year;
    • Have not used illicit drugs in the last 3 months; and
    • Willing to provide (small) blood, urine and saliva samples.
