Controlled Substances Trafficking Prohibition Act

Controlled Substances Trafficking Prohibition Act - Amends the Controlled Substances Import and Export Act to authorize individuals to bring into the United States a non-schedule I controlled substance if they: (1) enter the United States from Mexico; (2) do not possess a valid prescription or documentation which verifies such prescription; but (3) lawfully possess such substance for personal medical use, or for administration to an accompanying animal. Requires such a substance to be: (1) in an amount not more than 50 dosage units; or (2) if the individual does not lawfully reside in the United States, in an amount consistent with the individual's approximate stay in the United States. Declares that such Federal requirement does not limit any State from imposing additional requirements.
