Jeff Brubacher from Vancouver General Hospital published “Cannabis use as a risk factor for causing motor vehicle crashes: a prospective study.” The study has earned a great deal of press due to his finding that there was no increased risk of crash responsibility in the driver pool he studied for drivers with a blood THC level between 2 and 5 ng/ml.

About DUID Victim Voices:
Many voices are heard when a state considers stronger DUID laws. The voices of the marijuana lobby, law enforcement professionals, forensic toxicologists, and drug users typically dominate.

All states define alcohol DUI per se with laboratory tests that prove impairment by a blood alcohol level greater than .08 gm/dl for adults and greater than zero (or .02 gm/dl) for minors. Laboratory tests are routinely performed for all suspected alcohol DUI cases. Only 19 states define drug DUI (DUID) per se by objective laboratory tests.
Three additional states have established permissible limits for marijuana’s active THC in drivers, but these limits are a poor substitute for comprehensive drug per se laws. All other states use more difficult, costly, and subjective means to prove DUID on a case-by-case basis, with highly variable results.
