TUESDAY, July 19, 2022 (HealthDay Information) – – Automobile crashes and deaths are on the rise in U.S. states which have legalized leisure marijuana, a brand new examine finds.
“Marijuana, like alcohol and nearly each different drug, adjustments how you’re feeling and the way you behave. That’s the aim of a drug. And that adjustments the way you drive. All of us want to comprehend that driving after utilizing marijuana is a foul concept,” mentioned lead researcher Charles Farmer, vp for analysis and statistical providers on the Insurance coverage Institute for Freeway Security.
His crew discovered that after marijuana legalization, the speed of automotive crashes with accidents elevated by practically 6%, whereas deadly crashes rose by 4%. No improve in these crashes was seen in states that hadn’t legalized marijuana, the researchers famous.
These outcomes are in line with prior research, Farmer mentioned. “It’s changing into an increasing number of clear that the legalization of marijuana doesn’t come with out price. However marijuana legalization continues to be a novelty, and there’s hope that these early tendencies might be circled,” he added.
Farmer thinks there are methods to assist stop the results of driving excessive. “Perhaps, with the proper training and enforcement methods, states which are both contemplating or within the means of legalization can keep away from the rise in crashes,” he mentioned.
For the examine, Farmer and his colleagues checked out 5 states that legalized leisure marijuana for folks 21and older (Colorado, Washington, Oregon, California and Nevada) and in contrast them with states that didn’t legalize pot (Arizona, Idaho, Montana, New Mexico, Utah and Wyoming).
They discovered that after legalization, however earlier than retail pot gross sales began, the speed of automotive crashes with accidents jumped practically 7%. After gross sales started, the crash fee dipped barely (lower than 1%), however the fee of deadly crashes shot up about 2% earlier than and after retail gross sales started.
Typically, drivers below the affect of marijuana drive slowly, the researchers famous. They could not be capable to keep away from a crash, however their decrease velocity could make the collision much less lethal, Farmer famous.
In earlier research, Farmer’s crew discovered that marijuana use impacts response time, highway monitoring, lane conserving and a spotlight, all of which might make a crash extra probably.
Farmer would not imagine marijuana legalization is the one explanation for rising collision charges, and the examine cannot show a direct cause-and-effect relationship. And in contrast to alcohol testing, there aren’t any goal measures of impairment linked to marijuana, so it is not doable to precisely account for the function marijuana performs in automotive crashes, he mentioned.
The adjustments in crash charges diverse by state: Colorado had the most important soar (18%) and California the smallest (6%) after each legalization and the beginning of retail gross sales. Nevada’s fee fell (7%). For deadly crashes, will increase occurred in Colorado (1%) and Oregon (4%), whereas declines had been present in Washington (2%), California (8%) and Nevada (10%).
Alex Otte, nationwide president of MADD (Moms Towards Drunk Driving), mentioned, “We all know that driving impaired by any drug, alcohol, marijuana or in any other case, is 100% preventable. It is not an accident. It is not a mistake. It is a alternative.”
What’s wanted is to alter the tradition so folks perceive that it is not protected to drive after utilizing pot, she mentioned.
“We hear on a regular basis in popular culture issues like, ‘Perhaps I am a greater driver once I’m excessive’,” Otte mentioned. “I feel folks simply aren’t conscious, as a lot as they’re with alcohol, that there’s such a danger related to driving below the affect of marijuana or different medication, and I feel a variety of it comes right down to consciousness.”
Sooner or later, Otte hopes there might be methods to quantify pot’s results on driving, like there are for alcohol.
“We all know that roadside assessments and issues like that to assist an officer decide if that particular person is protected to drive are so vital and so wanted,” she mentioned.
Impairment by any drug is a menace to you and everybody else on the highway, Otte mentioned. “Even one particular person injured or killed is one too many,” she mentioned. “I need folks to know that it is a alternative they usually have the choice to make the proper alternative and to not drive when excessive.”
