One in five cannabis users have reported waiting less than three hours after cannabis use before driving in a survey of ACT cannabis users following the decriminalisation of the drug in 2020. The researchers surveyed 385 cannabis users about their driving habits, and say 21.6% reported driving within three hours of use, 10.6% reported waiting 4-6 hours, 46% waited 7-24 hours, 9.4% waited 24+ hours and 12.4% didn't drive at all. The researchers say there is mixed evidence around how dangerous driving after cannabis use can be, though previous studies have shown evidence that THC-induced intoxication can impair driving. Those who drive less than three hours after consuming cannabis are especially vulnerable to a positive roadside drug test, the researchers say, putting them at risk of losing their licence or facing criminal conviction.
