hey i have a quick question, ive been shooting for about two months now, and i buy from about three different people max, well now two due to my question. One of my long time dealers who is also the same guy who started me on shooting goes out of town to get his dope from a mexican (Tar heroin) but anyways my problem is that his and only his shit seems to give me really really severe hives within a minute or two of shooting it, not only do i become covered in hives from head to toe, but my breathing becomes extremely restricted, it also seems that the more ive done the worse the symptoms have become. The breathing has become so restricted that i have even considered callin 911 in fear that i am going to die. So my question is, does anyone think it must just be something the dope is cut with that i have an allergic reaction to? because not one other persons dope does anything even remotely close to that to me..... i asked him about it personally, but he is convinced that i must have just missed the vein or something, but no i am certain that i did not, because im not stupid and i have experienced the pain of missing the vein and it is not a feeling that i could overlook more than once. So any ideas or suggestions would b greatly appreciated, and for the record i just decided to completely stop buying his shit all around due to the fact that getting high is not worth going to hospital over and most certainly not worth dying over, so anyone and everyone please reply, thank you.
