Although I highly recommend you to stay clear from any form of injecting, intravenously or otherwise, since the process of preparing a shot and injecting it is already very addictive in itself, and once you've injected it's very hard to use other drugs without doing it by injecting.
However, for the sake of harm reduction I'll answer your question the best I can. When injecting intravenously, always insert the needle towards your heart, so you don't inject against the bloodflow. So when you inject in the crook of your arm, point the needle towards your shoulder instead of your hand. It's also very important to always make shure you're actually in the vein before you push down the plunger of the syringe, to prevent missing your shot and possibly causing an abscess. When you think the needle is in a vein, slightly pull the plunger, if you're in a vein a cloud of blood will enter the syringe and you'll know you're in a vein. If you pull on the plunger but no blood enters the syringe, pull your syringe/needle out, remove the used needle from the syringe and safely dispose of it by putting the cap back on it and place a new unused needle on the syringe to repeat the injection process 1 cm or half an inch further up your arm. But like I said, please stay away from the needle or you'll regret it for the rest of your life and whatever you do, stay safe.
No. If a vein is blown it can no longer be used for an injection.
No, it is injected into a vein, not the testicles.
idk i want to find out if they can sting you in a vein and inject their venom directly into your bloodstream and what would be the counsquences of that
The most common ways are to snort, swallow, smoke, inject into a vein, or inject into a muscle.
When someone undergoes spider vein surgery, their doctor will typically inject a chemical agent into the vein which will cause reduced blood flow and fading of the vein.
There are two major sites, the jugular vein and the tail vein. The jugular vein is much larger but cattle are often restrained in a neck chute which can make it difficult to safely inject into. The tail vein runs straight down the underside of the tail but is much narrower, so it is harder to inject into but is generally more accessible in dairy cattle.
The most common is the jugular vein.
A second, more or less.
In EMS, we pull back slightly on the plunger to determine if we're in a vein. If blood enters, the needle has struck a vein, and you're clear to inject.
She probably should
I'm no doctor, but I'm a frequent needle user. In my opinion, you missed. I've never shot up meth, but i bang Oxycontin on a daily basis. First of all you shouldn't inject into your breast. Not sure why, but I've read it everywhere (along with neck and genitals). Anyway, in my experiences, swelling and soreness is due to missing the vein. I'd suggest rubbing it and eventually it should go away.
Veins carry blood back to the heart.
