The administration of THC and CBD is not associated with driving impairment or an increased risk of motor vehicle accidents, according to a newly-released study published by the journal Brain and Behavior.

For the study researchers examined several reports that assessed the driving abilities of people following the use of an oromucosal spray which contains equal parts THC and CBD (Sativex).

“Real-world registries did not show any evidence of an increase in motor vehicle accidents associated with THC:CBD oromucosal spray,” the study reports. “The majority of patients reported an improvement in driving ability after starting THC:CBD oromucosal spray.”

Researchers conclude by saying “THC:CBD oromucosal spray was shown not to impair driving performance.”

Sativex, which was used for this study, is legal in multiple countries for medical purposes.
