Here is how to hit a vein in your arm if you are having trouble with or are running out of the veins in those two usual "junkie spots". Listen up, guys:
Run hot water (as hot as you can stand) over the skin surrounding the vein in question and really over as much as your arm as possible. This should greatly dilate a large number of veins. Shoot in to the TOP of your wrist or forearm, wherever vein is larger, putting very hot water on the tops of your wrists for several minutes will make some enormous and easy-to-hit veins pop. (FYI, don't be an idiot and shoot while you have hot water still running over your arm, and sterilize the injection site). Make sure you read about how to properly anchor a vein and if possible have a friend help you register that you're in. Do your research and fully read the IV-injection guide here on Bluelight. DO NOT shoot into those tiny-ass veins in the bottom of the wrist, they are tempting because they are obviously close to the skin but will almost always blow. Only an incredibly steady hand of perhaps a very well-trained RN could hit and shoot in to one of those. Hospitals use the veins running along the top of the arm without even trying to expand them; if you can see them at all (and they are the big veins which may barely be apparent somewhat deep under your skin) then you can hit them, you just need to go quite a bit deeper with the needle. Make sure the blood is dark red and not bright red; you don't want to shoot in to an artery!
It sucks and is a little risky to shoot a shot above a vein, but shooting a shot into the muscle below the vein can cause weeks of inflammation and if ANY bacteria was in the shot quite likely a serious abscess. I will leave all the information about being sanitary with injections for the main IV-users guide on Bluelight.
As a last resort, take a very hot shower or bath (preferably a bathtub as this soaks all your veins in very hot water) - you'll see hundreds of easy injection sights, along your bicep, forearm, the top of your hand (be careful there...) and a whole lot more in your legs and feet if you are really desperate, or have IV'd to the point of all the veins in your arms being ruined. You would be surprised at how many people fuck up all the veins in their arms, I'm about 15% of the way there and have skillfully used about 400 syringes in my lifetime. 40 packs of rigs go by real quick for an addict.
DO NOT inject into your neck as this could be deadly. If plugging the drug (shoving it up your ass with an oral syringe, works decently close to IV) is not enough of a rush for you or is too weird then you have a life-threatening problem. A few people have dared inject into the neck and a lot of them have either had very serious complications or died from overdose. If you have ruined all the veins you have even after taking a hot bath but can plug the drug, you should do that.
There are also some great veins if you are a male and have an erect penis of decent size - I noticed a potential vein on my dick once and the IV went very smoothly when it was erect. No, I am not a part of the gay meth scene for those who might wonder... I also have a 9" dick. Fucking wish I had a 14, lol. I have IV'd for some time and had my GF do it who was also quite skilled, so I wouldn't recommend this for an amateur. Any fuck-ups there would be unpleasent and might even result in the amputation of your penis!!!!! There was a very obvious vein along the front of my penis, I couldn't easily find a vein in my arm and had to try being the fucking risk-taker (but safety-promoter) that I am. Don't shoot into the expanded muscle in the back, it is filled with blood and muscle but that blood is making your erection. It's not going anywhere.
Always use "Wound Wash" (from CVS or Walgreens) to make your shots, it is exactly the same solution used for IV's in the hospital. Tap water can contain contaminants and contact solution can also be dangerous because of various cleaners. Always buy a box of alcohol swabs as well. The investments are well worth the potential complications.
I know that in my area two pharmacies sell syringes without requiring any prescriptions or paperwork signed: Rite Aid (max 1 pack of 10 syringes) and Walgreens (I've found no limit) although I have not yet tried to purchase a box. It may be a regional law or something strange like that in which case you will either have to try and possibly fail at a few pharmacies (you have to be older than either 16 or 18 at Rite Aid, not sure), or at most major cities you can find a "needle-exchange" program that will give you 30 rigs a week for free, and will process the same number for disposal each week. The sign-up process is simple and they also give you a free storage container for used syringes. There should be a "needle-exchange" program available to everyone over 16 at every fucking pharmacy in the world IMO. But then again some people say the government invented HIV to kill off black people, hey, it might be true. The secret world government running all these illusions of "sub-governments" which control us are pretty twisted.
Maybe a moderator could turn this in to a sticky, it would help people obtain rigs and miss veins less often.
