The problem with legalization is twinfold. One pitfall is that state residents who use the drug make themselves unmarketable to the federal government for anything from miltary service to federal employment, and security clearances. The second problem is how does a state determine if one is driving under the influence, and how long after partaking does one remain in a state illegal to drive a motor vehicle? I believe people who are ADD and AHAD are destroyed by the use pot, they cannot cope as do normal people who may have more/larger active brain mass. Trump is right that the federal government has a say on DRUGS in this country - he is trying to stop the drugs coming into the USA, from Mexico, S. America and Asia/SE Asia, Mid East. Regulated selling of drugs as prescriptions might be possilbe but for those ADD,AHAD people it is a serious no go. States Rights Issue maybe but since illegal drugs transit US Boarders or state lines jurisdiction is in question - the federal government does have the FDA - and the FDA is the bottomline on allowance/usage of drugs and supplements.
Fascinating. Then why are those in Congress/Senate etc, not randomly drug tested like those way down on the private sector food chain are?
