Harm Reduction Injecting into artery vs vein and blood differences

[curiousgeorge44]

Is arterial blood always "frothy" and bubbly? Will it always push the plunger back?

I read that veinous blood is supposed to be dark and arterial is red or pink, but I've been using my forearm veins lately and the blood I get upon registering is usually red, not dark red, but also not frothy and bubbly and the plunger does not get pushed back. I go ahead and push the shot in, and then when I register again for the 2nd or 3rd time as i'm pushing the shot in, I notice that I start getting some darker blood.

I'm using cocaine btw.

Is it possible that I'm shooting into an artery and a vein?

Reason I even ask is because I feel like wouldnt the pain be numbed out some because of the coke?

Probably a stupid question, but I was wondering this since I've been running out of veins lately and have hit a few arteries while searching and don't want to do that again.

if you hit an artery you would know my man, i hit an artery once and it felt like my hand got hit by lightning, heart instantly starting racing, hand swolled up to the size of a balloon. you can tell a vein from an artery by putting your finger on the vein/artery and if it pulses its a artery orhter wise its a vein. hitting arties are extremly dangerous, please be careful!
