CBD Doesn’t Impair Driving, Landmark Study Finds, While THC’s Effects Fade In Hours
Small doses of CBD appear to have no significant impact on driving, according to first-of-its-kind research published Tuesday in the Journal of the American Medical Association.
Similar doses of THC, meanwhile, were associated with short-term impairment “modest in magnitude and similar to that seen in drivers with a 0.05%” blood alcohol concentration, the study found. After about four hours, signs of marijuana impairment faded.
“These findings indicate for the first time that CBD, when given without THC, does not affect a subject’s ability to drive,” said Thomas Arkell, the study’s lead author.
