Trump Administration to Study Marijuana and Driving
The U.S. government will conduct a study this year examining “marijuana as a causal factor in traffic crashes” under legislation President Obama signed into law last month.
As part of the review, the Department of Transportation will look at methods for detecting marijuana-impaired driving, including ways to differentiate the cause of driving impairment between alcohol and cannabis.
The department is directed to issue a report within one year making recommendations on a possible impairment standard for driving under the influence of marijuana, similar to the 0.08% blood alcohol content limit that is used to legally define intoxication in U.S. states.
The report will also include recommendations on “effective and efficient methods for training law enforcement personnel, including drug recognition experts, to detect or measure the level of impairment of a motor vehicle operator who is under the influence of marijuana by the use of technology or otherwise.”
