The U.S. Customs Service enforces Federal laws and regulations, including those of the Drug Enforcement Administration (DEA) and the Food and Drug Administration (FDA).
A new bill was recently passed by Congress that amends a portion of the Controlled Substances Act (21USC956(a)).
This amendment allows a United States resident to import up to 50 dosage units of a controlled medication without a valid prescription at an international land border. These medications must be declared upon arrival, be for your own personal use and in their original container . However, travelers should be aware that drug products which are not approved by the U.S. Food and Drug Administration may not be acceptable for such importation. FDA warns that such drugs are often of unknown quality and discourages buying drugs sold in foreign countries. Please go to

The United States Federal Food, Drug, and Cosmetic Act (21 U.S.C. sections 331(d), and 355(a)), which is administered by FDA, prohibits the interstate shipment (which includes importation) of unapproved new drugs. Unapproved new drugs are any drugs, including foreign-made versions of U.S. approved drugs, that have not received FDA approval to demonstrate they meet the federal requirements for safety and effectiveness. It is the importer's obligation to demonstrate to FDA that any drugs offered for importation have been approved by FDA.
