In the study conducted by HLDI, researchers found that between January 2012 and October 2016, accident claims increased by 4.5 percent in OR, 16 percent in Colorado, and 6.2 percent in Washington.
M - Marijuana enthusiasts might fancy the grass a bit greener in states with legalized recreational use, a list that now includes eight states plus the District of Columbia.

A study released past year by AAA's safety foundation found legal THC limits established by states with legal marijuana have no scientific basis and can result in innocent drivers being convicted, and guilty drivers being released.

A new study that links vehicle crashes to marijuana shows auto accidents have gone up nearly three percent in three states where it is legal. Control states included Idaho, Montana, Nevada, Utah and Wyoming, plus Colorado, Oregon and Washington prior to legalization of recreational use.
"Colorado has had legal pot sales the longest and it is showing the greatest effect", Moore said, according to CNBC.
The studies took distinct angles on marijuana and driving, and it's possible that fender benders in Colorado have gone up since pot was legalized even as fatalities stayed flat.
Of three states, Colorado, where the drug has been legal since 2014, saw the largest estimated increase in claim frequency.
However, Moore believes this provides clear answers that crash risks have increased in these three states where marijuana is legal, but understands that more research needs to be done. "It is something states need to look at when they're considering legalization". An additional 17 states also allow limited access for medial use.
Mason Tvert with the Marijuana Policy Project, which fights to legalize marijuana, had something to say about that. But based on the data the HLDI crunched, perhaps it's best if drivers in Colorado, Washington and OR started walking and biking a bit more.
