Vaping cannabis derivatives like THC and CBD can show signs of a “modest” impairment for up to four hours later, per a study published on Tuesday, December 1, in a study published by JAMA.
“[Our] study shows that cannabis-induced driving impairment varies with cannabis strains,” said study co-author Dr. Johannes Ramaekers in an interview with United Press International news wire service. “The implication for the general public is that the cannabis-induced driving impairment should be acknowledged as a public health risk while taking into account that impairment may differ between cannabis strains and depends on time after use.”
This is a developing story.
