Recreational marijuana is legal in California, but stoned driving is still hard to detect

Brad Branan, The Sacramento Bee, January 21, 2018

When a 22-year-old Hayward man allegedly slammed his Cadillac into a California Highway Patrol vehicle and killed Officer Andrew Camilleri on Christmas Eve, he was under the influence of alcohol and marijuana, officials said.

CHP reported that Mohammed Abraar Ali had a blood-alcohol level of .11, above the state limit of .08 for motorists. While it’s not clear how the agency documented Ali’s cannabis consumption, he said he got high at a Christmas party, authorities said.

Proving intoxication from weed is more difficult than it is with alcohol, as law enforcement does not have a device like a breathalyzer for alcohol. Without such a tool, law enforcement must rely more on roadside sobriety tests.

The new year will mark the official start of recreational marijuana sales in California, and there are fears it could lead to more impaired driving. Among U.S. drivers killed in crashes who tested positive for drugs, more than a third in 2015 had used marijuana.

At the University of California San Diego, researchers are trying to help police detect whether a person is too high to get behind the wheel.

Recreational marijuana sales start Jan. 1. Here's how weed does, and doesn't affect your health

Gary Robbins, San Diego Union Tribune, December 4, 2017

The FDA cried fraud in October, accusing companies in Florida, Colorado and California of illegally selling marijuana-derived products that supposedly could prevent, treat or cure cancer.

The advertising claims were unsubstantiated, said the FDA, and the products hadn’t been submitted for approval.

It was a public shaming that also served as a timely buyer-beware message for California, where the sale of marijuana will be expanded from medical purposes to recreational use in January.
