the numbers for dwi is .08 how is marijuana measure for the amount of impairment
.08 refers to the amount of alcohol in a person's system. It is commonly referred to as the legal limit. Alcohol is not illegal, so it is not illegal to drink some alcohol and drive. What IS illegal is to drink an amount that impairs your driving ability, or puts you over the legal limit. Marijuana, on the other hand, is illegal in all but a few instances (medical marijuana). As a result, driving with ANY amount of marijuana is illegal. Most ethical crime lab "scientists" will admit that the amount of marijuana reflected in a blood test shows only recent or habitual use, not a level of impairment. The other way the police will attempt to measure the level of impairment from marijuana is through field sobriety tests performed by a drug recognition expert (DRE). These tests, however, are not valid scientifically and readily discredited by an experienced DUI defense lawyer.
