I don't see in Article 1, Section 8 of the Constitution where the federal government was given any power over drugs at all. It's in that same section where they have power over Anthrax, Nerve Gas, and Nuclear Material. You know, the DEFEND THE NATION section.
No. Drugs are and should be subject to the police powers of the States. Not the federal government.
The others you list are recognized weapons of war that cause mass casualties.
