LMAO at "coke and sope?".. I really hope you mean "dope", like heroin? if not, your friend needs help, seriously.. for IVing soap... and coke on top of it. But assuming, this was a typo and you meant dope.. what do you mean here exactly? As in they aren't getting high, there is some blood coming into the rig, but not as much?
Like is it just barely coming in when your friend is pulling back the plunger and registering, with a light red coloration? It should, be a darkish red color, more than pinkish light red color.. It is just one of the signs you are in an artery, not a vein when it slowly comes into the rig, and its a bright, almost pinkish red color.. but it also hurts like a bitch to miss a shot or hit an artery! I just did it for the first time, a couple weeks ago with a shot of coke.. it sucked! I have been IVing for like 4 years now and that was my first actual artery hit, and OUCH! It fucking hurt! It should be like a huge cloud of darker, than lighter red blood coming up when pulling the plunge back to register the majority of the time, when registering for a shot. However, I have successfully shot up many times IV, and had a big cloud of bright red blood come back into the rig when registering.. and it all worked out! its just usually a more "crimson red" darker coloration IME.
Also.. you said, it doesn't hurt your friend but he isn't getting much of a rush? Well then maybe your friend is getting ripped off with some garbage coke/dope? Maybe, he is missing and somehow, not getting that painful, burning sensation that tends to happen when any one misses a shot of anything IV? I am trying here, but your post is a bit jumbled up, with lots of typos.. so I am not entirely sure what you mean, just working with what you wrote.. trying my best to help you guys out. You may want to do a spell check next time? sorry, again.. not trying to be a prick.. I truly am trying to help out here. But I am surely not the only one on here who could be a bit puzzled by your post, with all of the misspelling and grammar issues? am I? I am just a bit on the "blunt", brutally honest side and don't sugar coat shit I say/type to anyone.. just tell it like it is.. so, don't take any offense.. that's just me.
