Weird. Running/adrenline exercise does nothing for me. I don't get adrenaline rushes like people talk about, have never felt one. I only get rushes from drugs or feel good from them etc. I figure that's what sets me apart from others who seem to get all these amazing feelings in real life without drugs. I wouldn't want to be like those people though. That seems weird to me
It's possible that you're allergic to a drug or maybe how you take it. For example, you say you smoke crack. Do you smoke heroin as well? Maybe try inhaling cocaine and inhaling heroin (separately). That's safer but see if that changes anything. You could be allergic to the smoke from one or both of them
If I smoke a cigar I'll feel sick towards the end of it, but if I inhale snuff tobacco (snuff) I don't get sick and it makes me feel good. Needless to say I haven't smoked a cigar in several years. There's no point
