America's highways are decidedly less safe on April 20, a day when stoners publicly celebrate marijuana use.
Why? Researchers report there's an uptick inon that evening, which for decades has been a counterculture holiday revolving around pot use.
Your risk of dying in a fatal wreck increases about 12 percent on that date, comparable to the increase in traffic risk that's been observed on Super Bowl Sunday, according to the analysis of crash data.
