“Our study proved that isn’t true”.
Another study released a year ago by AAA’s safety foundation stated that legal THC limits established by states with legal marijuana have no scientific basis, and could result in innocent drivers being convicted while guilty drivers are released. “There would be more rear-end collisions and people running off the road and those kinds of things”.
It found a 3 percent increase in collision claims in those states compared with Wyoming, Idaho and Nevada, where it is not legal.
The study found that collision claims following legalisation are up 16% in Colorado, 6.2% in Washington and 4.5% in Oregon.
The study shows more drivers admit to using marijuana and its showing up more frequently after a vehicle crash.
Those findings contradict another recent study on the effect legalization has had on road safety.
The study released Thursday already has its critics.
Colorado and Washington approved recreational marijuana in 2014, with OR legalizing it a year later.
Investigators from the University of Texas-Austin evaluated crash fatality rates in Colorado and Washington pre- and post-legalization.
Further, measuring THC levels in the blood is not as easy a measure of impairment as blood-alcohol level is, since the psychoactive compound in marijuana is stored in the body’s fat cells and can show up in the blood long after the effect has worn off.
Marijuana advocates question the study’s comparison of states with such varied populations.
King said impaired driving is especially troubling for him because York County leads the state in fatal vehicle crashes.
But Dr. Scott Krakower, assistant unit chief of psychiatry at Zucker Hillside Hospital in Glen Oaks, N.Y., noted concerns that pot can increase the overall risk of vehicle accidents. The researcher in their study, considered factors like number of road vehicle and controlling the states, gender, and age of drivers, weather and ensuring driver with the claim are employed and comparing those factors with neighbouring states same fluctuations. The threshold before a search is performed is also lower for minority drivers than it is for whites, according to the researchers at Stanford behind the Open Policing Project.
The study was half of what Aydelotte wanted to conduct, as he also wanted to look into death rates from violent crimes related to marijuana use, but those numbers weren’t available, he said. “We have a lot more to learn”.
“You really have to look at carefully the data and what they are talking about”.
One particular challenge is coming up with a way to judge whether driving ability has been impaired by pot.
HLDI notes that more drivers admit to using marijuana, and it is showing up more frequently among people involved in crashes. This is interesting as it goes against what many have to say about smoking the drug.

Highway stops have always been a tool in the war on drugs, and remain a charged issue amid a furious national debate about police treatment of minorities.
