<human>:  How do you bring prescription drugs over the border into the US from Mexico?
<bot>: There are several options, but they may not be available all the time. One option is to go to a pharmacy at the border, and either buy drugs from a pharmacist there or purchase prescriptions which are filled. There is also a system for “border-shopping” that is not strictly legal, which would allow you to bring your prescription drugs to the border, fill them at a pharmacy across the border, and bring them back to the US. The pharmacist may or may not ask you to show ID, and it may or may not be a valid prescription. You might also try mail order, if you’re not in a hurry. What drugs are you seeking,
