DUID Victim Voices

Education and promoting effective laws to reduce Driving Under the Influence of Drugs (DUID)

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. DUID Victim Voices represents the interests of the victims of drugged driving, providing fact-based education and a victim perspective to decision makers and to the general public.

Background

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 17 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.

A 5 ng/ml standard is still far too high.  … READ MORE

Good Data, Bad Statistical Inferences

A February 2015 report from NHTSA’s 2013-2014 survey[1] shows a continued decline in the percentage of drivers under the influence of alcohol.  In 1996, 16.9% of those surveyed had a Breath Alcohol Concentration (BrAC) greater than .05 gm/210 L, Read More

The Futile Search for the “Right” THC per se Level

THC (delta-9 tetrahydrocannabinol) is known to be the primary psychoactive ingredient in marijuana that causes driving impairment. For years, legislators and some scientists have sought a per se level of THC in a driver’s blood that is equivalent to Read More
