Current Legal Cannabis Driving Limits in US, Europe Are Ineffective According to Breaking Research in AACC’s Clinical Chemistry Journal

WASHINGTON, March 14, 2019 /PRNewswire/ — The level of cannabis that causes driving impairment in occasional marijuana users is actually lower than the residual cannabis levels found in regular users even when they haven’t consumed cannabis recently. These new findings, published today in AACC’s Clinical Chemistry journal, add to a growing body of evidence suggesting that no legal driving limit for cannabis can catch impaired recreational users without unfairly penalizing unimpaired regular or medicinal users.

As more U.S. states legalize medicinal and recreational marijuana use, marijuana-related car accidents are also likely to rise—a trend that Washington, Oregon, and Colorado have already seen since approving recreational cannabis.
