(CBS) – Does driving while high have any impact on auto accident rates? Legalized recreational marijuana use in Colorado, Oregon and Washington correlates to about a 3 percent increase in auto collision claim frequencies compared to states without such legislation, according to a new Highway Loss Data Institute (HLDI) study. It’s the first one the group has conducted since the drug went on sale legally.
“More drivers admit to using marijuana, and it is showing up more frequently among people involved in crashes,” the study said.
The HLDI is affiliated with the Insurance Institute for Highway Safety, a nonprofit research organization that usually focuses on figuring out which cars are safest. The group is funded by auto insurance companies, which have a vested interest in not having to pay claims and — of course — hold a bias against impaired driving of any kind.
