I only smoke bud. I quit the cocaine, and the opiates a couple years ago. I really dont enjoy alcohol either, because that brings down my defenses (immune system, lack of judgement) until I become tempted to get some powder. Even in a room full of hotties and we are doing blow, none of us are interested in sex, only that next bump.

General rule of thumb, stay away from anything man made. Anything.

Sorry for your loss OP, but your friend knew the price to catch a fix. Sometimes, that price is a reminder of our mortality.

Take care, but also be careful who you lend your advice. Never trust a junky, some people can only learn from their own mistakes, albeit fatal.
