The CSA Provides a Personal Use Exemption for Controlled Substances Purchased Abroad. Does the Exemption Apply to Controlled Substances Bought from a Foreign Internet Site?
(This question and answer copyed from DEA Web Site) The Controlled Substances Act and DEA regulations allow you a personal use exemption to bring a limited quantity of controlled substances into the U.S. for your use only when you bring the controlled substances across the U.S. border in your possession (21 U.S.C. 956, 21 CFR 1301.26). It does not apply to controlled substances being shipped into the U.S. Purchasing controlled substances on the Internet and having them shipped to you in the U.S. is not permitted by the personal use exemption. Such purchases and shipments would be considered “imports” of the controlled substance even if the substance is for your personal use. Unless you are registered as an importer and in compliance with the requirements, such shipments are illegal and subject to seizure.
