Im not going to get real deep into this, but one major problem is not quick easy accurate test for law enforcement. You pull over a drunk, you have field sobriety and breath test to determine level of intoxication. You pull over somebody that's smoked dopeyiu can do field sobriety but Theresa no way to tell the level of intoxication. Sure they can do a toxic screen at a hospital but that will just show it in their system, but could be from 4 days ago.
