A U.S. study published earlier this year put 20 participants through common field sobriety tests and cognitive tasks after they consumed cannabis edibles or used vaporizers. In the Swiss study, all 33 participants exceeded the Driving Under the Influence of Drugs (DUID) legal limit for THC in blood after smoking CBD-rich marijuana, despite showing no symptoms of impairment.

For those who inhaled CBD flower, researchers found “no symptoms of impairment” and “no significant impact on driving ability.”
The findings were highlighted in a blog post from the...
