NORML seeks to promote public discussion and debate regarding the federal government's attempts to expand the scope and public expense of cannabis prohibition by massively expanding drug testing by law enforcement specifically targeting citizens who drive.
We all support the goal of keeping impaired drivers off the road, regardless of whether the driver is impaired from alcohol, cannabis, or other drugs. However, these zero tolerance laws are neither a safe nor sensible way to identify impaired drivers; they are a cynical attempt to
misuse the traffic safety laws in order to identify and prosecute cannabis consumers per se.
From the site:
Under this standard, any driver who tests positive for any trace amount of an illicit drug or drug metabolite (i.e., compounds produced from chemical changes of a drug in the body, but not necessarily psychoactive themselves), is guilty per se of the crime of "drugged driving," even if the defendant was sober.
