>>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.
