As I was saying about generic drugs from India, the US forbade US credit card companies from doing such transactions. I can't give a link or point to an exact law at the moment, but we (and this includes people I know in Europe) can no longer order online with a credit card like we used to.
I know what you're talking about..those were DEA scheduled drugs.. A substance need not be listed as a controlled substance to be treated as a Schedule I substance for criminal prosecution. A controlled substance analogue is a substance which is intended for human consumption and is structurally or pharmacologically substantially similar to or is represented as being similar to a Schedule I or Schedule II substance. tobacco has no such scheduling.
