Stoned drivers in Washington state are most likely to get in crashes from 4-5 p.m.
Saturday is their favorite day to do so.
And more drivers in Vancouver get into car accidents while high on weed than any other city in the state.
Those are the key findings of a recent study conducted by Seattle personal injury law firm Davis Law Group, which analyzed four years marijuana-involved collisions (2015-2018) reported by the Washington State Patrol. We share those findings on April 20 or 4/20, the national holiday for cannabis culture.
Only one cannabis-involved collision has been reported on 4/20 in the past four years: a 2017 collision in Snohomish involving a 19-year-old man. No one was injured.
There were 392 total marijuana-involved driving incidents reported in the time period studied, resulting in 37 fatal crashes. Additionally, there were 22 serious injury collisions, 110 minor injury crashes, and 215 collisions that did not result in any injuries. Eight collisions were recorded as “unknown injury.”
Two-vehicle collisions made up a majority of the total incidents (188). There were 169 single-vehicle crashes and 35 collisions involving three or more vehicles. Intersections played a major role in these incidents (102 crashes, 26%).
Among major roads in the state, Interstate 5 was by far the trafficway with the most collisions involving marijuana (57). Interstate 90 (11 crashes) and Interstate 82 (10) also had their fair share.
According to a Gallup poll, 70% of people think that people who drive while impaired by marijuana are "not much of a problem" or only a "somewhat serious problem," whereas just 29% said it was a very serious problem.
Driving impaired by weed is serious and causes hundreds of auto accidents every year across the country. Davis Law Group aims to raise awareness by illustrating the statistics surrounding the issue in our own state.

Vancouver comes in at No. 1 on the list with 19 weed-involved collisions from 2015-18. Despite having just the fourth-largest population in the state, Vancouver outdid big brothers Seattle, Spokane and Tacoma when it comes to driving while high. While just one of these collisions was fatal and one was serious injury, it speaks to the prevalence of stoned driving in the city.
