I had rohypnol many times in the early 90's, before the whole date rape thing, and it was legal to buy them in Mexico, claim 3 months worth at customs, and bring them into Texas. They were in boxes packed in blister cards of 10. 3 cards per box = 30 pills per box. You could legally bring 3 of these boxes back into the states by claiming them. They could be fun but also dangerous if you werent careful. To me it felt like a longer lasting xanax, but I retained more of my memories than i would on xanax. They are still available in Mexico, a reformulation, and it is no longer permitted to bring them into the states.
