Australian authorities urged to join global effort to answer cannabis impairment question

Australia’s state and federal governments and police forces have been urged to join a global effort to establish a reliable measure of cannabis impairment.

Speaking during a Penington Institute webinar exploring the safety implications of adult use on driving and the workplace, Johns Hopkins University professor of psychiatry and behavioural sciences Ryan Vandrey said there is still no way to predict whether somebody is impaired due to cannabis, despite the best efforts of the research community.
