San Diego, CA (KGTV) -- It's legal for Californians to smoke marijuana now, but how soon after lighting up is it safe to drive? UC San Diego researchers are trying to figure that out to help both users and law enforcement.
UCSD's Center for Medicinal Cannabis Research (CMCR) teamed up with the California Highway Patrol for the study, which was authorized by the California Legislature.
After an initial visit, study participants smoke cannabis and then undergo a driving simulation. The marijuana joints have different doses, from no THC to high THC.
"If you smoked this morning are you impaired throughout the day? Are you impaired for a couple of hours? Or are you not impaired? We're trying to answer that," said Tom Marcotte, co-director of the CMCR.
