Researchers from the United States and Canada have discovered that the number of car crash deaths involving cannabis is skyrocketing in recent years.
The team from Boston Medical Center, Boston University, and the University of Victoria adds that marijuana-related crash victims had a 50-percent higher chance of having alcohol in their systems at the same time.
The team found that cannabis use is also a risk factor for alcohol co-involvement, even at levels within the legal limit.
When it comes to impaired driving, researchers say drivers using marijuana don’t just endanger themselves, but their friends as well.
Despite the results, study authors note that testing for marijuana intoxication is still an inexact science.
