Where to Inject

Choosing an injection location should not be determined solely on where veins can be found. Some areas of the body are more safe to inject into than are others. Below is a list of injection areas in order from safest to least safe.

  1. Human skull. Arms: The upper arm is the best place in which to inject--there are relatively few nerves there and the veins are large. Just the same, the veins tend to roll, so this must be taken into account.
  2. Hands and Wrist: There are more nerve endings here and the veins tend to be smaller and more delicate and thus more prone to damage. On the positive side, they are easy to find and stable.
  3. Legs: These veins are at greater risk of forming blood clots. Interrupting blood flow in the legs is particularly serious because these veins are the most important for bringing blood back to the heart.
  4. Feet: These veins are even more delicate than those in the hands. There is also relatively poor circulation to the feet which means that damage done is repaired slowly. Special care should be taken to clean the feet if they are used for injection because of the possibility of infection.
  5. Groin: The largest vein in this area--the femoral vein--is very close to the femoral artery. It is easy to miss the vein and hit the artery--causing the usual problems.
  6. Neck: Just as in the groin, it is easy to miss a vein and hit an artery. Hitting the carotid artery is potentially fatal. Even apart from injecting into an artery, damaging the veins that go from the brain is very dangerous. The brain needs blood more than any other part of the body.
