Hi Chris and thnks for writing,

In a word ... "NO"!

Serious Risks When You Buy Prescription Drugs in Mexico:

Drugs you purchase in Mexico may be counterfeit. Medical studies show that one in five drugs purchased in Mexico is counterfeit or substandard.
Do not assume that Mexican pharmacy employees have any medical training.
You have no recourse if the drugs you purchase are worthless or do you harm.
In many cases, you do not know where the drugs were made or how they were handled.
If you receive directions for use at all, they might not be in English.
Breaking U.S. laws regarding importation of foreign drugs may lead to your arrest in the U.S. Do not lie to U.S. Customs.
Breaking Mexican laws regarding purchasing of drugs may lead to your arrest in the Mexico. Penalties for drug offenses are strict, and convicted offenders can expect large fines and jail sentences up to 25 years. Unknowingly breaking the law, or getting a Mexican prescription, even unknowingly, from someone who is not authorized to issue it does not excuse a U.S. citizen from prosecution in Mexico.
You must declare the drugs at Customs upon your return. Customs permits people to bring back reasonable amounts of medications for personal use, but does not allow stockpiling or purchasing large amounts of drugs for what will be assumed is a commercial or resale purpose. If the medication is a controlled substance, a reasonable amount means up to 50 combined total doses.
If you do bring a prescription drug that is a controlled substance into the U.S. from Mexico, it must be for legitimate personal medical use. It should be in the original container, which must identify the substance and the name and address of the dispenser.
If you lie to customs about having drugs and you are caught, the consequences could be simple, like having the drugs taken away, or very serious, such as going to jail.
Although this is not a border issue, you should know that obtaining controlled substances from a foreign source via the internet or mail order is illegal unless you are an approved, registered importer with DEA.

Still thinking of buying drugs in Mexico? My advice: think twice. It isn't worth the risks you are taking with your health and your freedom.

I hope this answers your question,
Margot
