There was some guy arrested last year or year before for trying to purchase drugs the WRONG way, arrested in Mexico and held there for quite a while
Since we have not purchased anything more than cold pills over there, we cannot be considered any authority, but the way we understood it was that if you wanted prescription drugs, you had to have a script from a Mexican doctor AND, the person needing the script had to be present when submitting the script to the pharmacy.
Have not looked but there must be a web site somewhere????? just like there was for the passports??
Get your facts first, that is for sure.
