A study found people who started using cannabis before age 16 exhibited poorer driving performance even when they are sober.
Boston Globe
- The study “found heavy cannabis users using a driving simulator hit more pedestrians, missed more stop signs and red lights, drove faster, and left their lane more often than non-users, even after abstaining from the drug for at least 12 hours.”
- However, those who took up cannabis after age 16 didn’t exhibit the same behaviors.
- It was the first study to find poor driving performance by cannabis users when they are not actively high.
