Cleaner, this holds true if you have the meds on your person and you are crossing a border such as Mexico or Canada. As far as mail order goes, the fda will not allow prescription meds really as they feel the meds don't meet US standards. I can tell you this from experience unfortunately. This is why the meds are usually hidden when sent to you if from a foreign source. Then if the meds are scheduled, then the DEA won't allow them period. Honestly there is no grey area, it is pretty clear if you read DEA, customs, and FDA requirements. But I have pretty much told you in a nutshell because all that reading can be confusing. I hope I have helped.
