I'm on the side of Alan Keyes on this issue. This is a state issue. Certain states may wish to have unrestricted use of recreational drugs (Nevada?). Others may wish to use prescription or licensing of recreational drug usage. Others may want to tax it to death or make them illegal. Its up to each individual state. Tailor the system that works best for the local population. The federal government does have the right to levy taxes on imported goods. There is nothing dishonest on slapping a large tax on imported recreational drugs. It would encourage domestic production.
Nevertheless, I'm am not interested in being taxed, charged, threatened or penalized because of reduced productivity,improper behavior, addiction, abuse intervention or hospitalization that is a result of someone else wanting to get high. I believe that unrestricted recreational drug usage will be to my disadvantage. Restriction of drug usage can be accomplished without resorting to a "Nanny state" or unconstitutional laws.
Federal regulations have reduced our "laboratories of democracy" to 50 control groups.
