It's true! In many parts of Mexico, including Mexico City, this is not the case at all. Even in Guadalajara, which is in the same state as PV, you can't buy this stuff without a prescription. But I was in PV and my partner had a headache so we wandered into a pharmacy in an upscale neighborhood to buy some ibuprofen and to our surprise the pharmacist was a hell of a saleswoman! We walked out with a variety of benzos and boner pills.
