Fatal crashes more likely during annual 4/20 cannabis celebration: study (CHEOS)
Drivers across the United States are significantly more likely to be in a fatal car crash in the hours immediately after annual 4/20 cannabis celebrations, according to a new UBC study of 25 years of official data.
The study, published Monday in the medical journal JAMA Internal Medicine, analyzed data from the U.S. National Highway Traffic Safety Administration beginning in 1992 and found a 12-per-cent increase in the risk of a deadly accident after 4:20 p.m. on April 20 – an effect the two authors likened to the proven drop in road safety on Superbowl Sunday.
Dr. Staples said he got the idea for his study while seeing people intoxicated from downtown Vancouver's annual massive 4/20 party stream into the emergency room of St. Paul's Hospital, where he works as a general internist.
