UPDATE: Washington State University is working on technologies that will allow the State of Washington to breath test for marijuana using a portable device. The airport and customs agents currently can test for marijuana on the breath. Just because it is legal does not mean you should do it. Al Armstrong at Armstrong Alcohol and Drug Recovery, LLC in Tukwila, WA, has 30 years experience on the front line working with marijuana DUI offenders/clients, cannabis/marijuana assessments/evaluations. He remembers in the 80’s when it was said “powder cocaine” was not addictive. Today, unfortunately many of those clients, offenders, patients and peers are in and out of jail, treatment, prison, dead or have found total freedom from alcohol and drugs. When you get a chance buy a book called “With Love, From Dad” (Why Haven’t Marijuana Smokers Been Told These Facts) by Malcolm E. Smith. Marijuana is a hallucinogenic and the brain identifies all hallucinogens as poison that is why we have hallucinations. Other drugs in this group are LSD, PCP (Phencyclidine or Angel Dust), mushrooms, Ketamine, Mescaline, Peyote, MDMA, Ecstasy (also a stimulant), Bath Salt and sherm (wet).
