I recently for the first time in all my life (I'm 35 yrs old) tried cocain, I've done it now a few times.. the other night I got high, and I believe I may have been laced with something else.. my suspicion is heroin.. I felt way different then any time before.. at first I started feeling nauseous so I did a few more lines and after a few mins I felt really down not up like coke makes you feel.. I started feeling very hot, all I wanted to do was lay down, so I did.. and when I was laying down I felt so high unlike anything I ever felt befor.. my body felt numb and like a tingling sensation, especially if someone touched me.. I was also kinda seeing weird images on and off.. then I got real cold.. I felt like I was sleep but I wasn't I was aware of my surroundings but eyes closed.. someone please help me understand what happened??!! I need to know!! Thank you!!
