To the person who was asking about mailing to syringes to Vegas, PLEASE READ!!!!
I know that the Mod said that you didn't need to worry about rigs for your trip, but as someone who has been in the same boat, for heavens sake, please don't listen to him... I went to Vegas for a weekend with my girlfriend and brought everything but rigs only to find out that (probably due to illicit drug use and how bad Vegas is already) that it is IMPOSSIBLE to acquire a syringe without a prescription that dictates that it needs to be injected. I personally tried absolutely everything I could find here or on several other sites to scam a pharmacy into selling me one and failed. I also called just about every pharmacy or store that may have syringes and had no luck either, well, at least nothing small enough to use IV... if someone KNOWS of a pharmacy in Vegas that will sell syringes without a scrip, please let me/him/her know, i would love to be wrong on this...
