haha, yeah, i'd feel strange purchasing a syringe as well. but don't dispair, you can tell if someone is an IV drug user or not. i used to work at a retail pharmacy, and when people would come in and buy needles it was easy to tell if they were drug users or not...trust me. i'm sure you don't fit that description. thankfully, i work in a hospital now, so i can just get a syring/needle when i need it. pretty convenient.
