Consequences of Smoking Marijuana and Driving in California
Effects of THC on Driving AbilityCA's dui laws make driving with alcohol or drugs or a combination of the two a crime if your driving is impaired. The studies are not 100% conclusive but most show that driving stoned makes a for a better driver than the sober version. Unfortunately the DMV disagrees. If you are stopped while stoned, the cops will take a blood test and send it off to the laboratory. Several weeks later you will find out if you are going to be charged for rolling stoned.
What Your test Result MeansUnfortunately many judges and prosecutors don't know how to interpret the tests. Don't know or don't want to. Marijuana stays in the system long after the stoned effect is gone. It is stored in fat cells as metabolite. Someone who smokes once a week will have a high metabolite reading regardless of whether they were driving stoned or not. The only measure the counts is the amount of the active ingredient of THC in your system and this doesn't even prove impairment.
What to Do?You've got to realize that although some alcohol is tolerated in drivers this is basically a zero tolerance state. And that's especially true for drugs including the nearly legalized marijuana. Realize that even if you haven't smoked before you drive, but do smoke often, a blood test will yield a high THC metabolite reading that can be misunderstood. So smoke 3 joints before you smoke 3 joints but take the bus.
