I have recently experimented with different new drugs, and one thing led to another and before i knew it i was sniffing heroin. Tonight i tried shooting it in my arm after a lot of research online on what to do. Right after I shot my palm began to burn terribly then my whole hand started going numb. My head is spinning, this was to much to intense I want it over! what is going on with my hand? please somebody help! I am not looking for a lecture i know what I did was absolutely the stupidest thing I have ever done! I threw all that crap away and I am never doing it again! I just need some help i am very scared!
