I live in Dallas, but I've found this method pretty much flawless everywhere I've been. Granted, it can be VERY tedious. But it works, depending on how patient you are willing to be.
Your appearance has a lot to do with it. I am a long time IV Heroin user, but you would not know it from looking at me (if i had long sleeves on). Whenever i'm in a new city trying to find somewhere to buy points, I make an effort to look and act preppy, clueless, and preoccupied. There was a pharmacy here in dallas that sold rigs to anyone for YEARS but they were in a nice neighborhood and had to stop beause so many "scary, dirty looking people" (their words, not mine) were coming in multiple times a day buying single points. Know what your asking for. I prefer 28g 1cc BD Insulin syringes. I've also found it helps not to ask, but state what you need, i.e. "A pack of 28gauge 1cc BD syringes, please" instead of "can i have a box of needles?"
It is not illegal for pharmacies to sell syringes, but it is up to each establishment whether or not they will do it without a perscription to insulin in your name at that pharmacy. In this dilemma, i've had the "they're for my mom/dad/aunt" thing work as well as the "im from out of town".
Also another thing i've found works tremendously well in a pinch is using Allergy syringes. Claim to need a pack of 28 gauge allergy syrnges for your epinephrine for your severe peanut/bee/whatever allergy because you are in a hurry. I don't like using them as much as insulin syringes but they are basically the same.
Anyway, i've found that if you go from pharmacy to pharmacy doing this, eventually you will get some. You would think Worse neighborhoods sometimes have a better chance, I've found that in really nice areas if your dressed right you raise less suspicion. I try both.
Basically the key is confidence, and talking and acting like your not doing a damn thing wrong. Because your not. Theoretially if you got pulled over right after buying them and the cop found them, as long as you didnt use them, theyre not illegal to have. Though it would give the cop a damn good probable cause to search your car, and if you're a junkie like me that is NOT something I want because i guarantee there is something wedged somewhere in there I dont want a cop to find.
Hope this helps.
