I've been a heroin addict for 4 years now, and shooting for the past 2 1/2. Lately i have been having such trouble finding a good vein. I have very small and hidden veins so its hard as it is, without the scar tissue from all my fuck ups when i first started hittin myself!! For instance, i have this nice vein on the top of my wrist that buldges, but when i try and get it...nothing. I put the needle in at the right angle and everything!! I need a map of like the veins in the human body and where they are! Can anyone help?? I have a few veins i can get most of the time, but i cant use them over and over cause that will ruin them. Does anyone know where there are some good veins?
