I have been using coke for almost 6 months now and I could say that my experiences were very different each time. It is as if I have been using completely different drug each time. Do they cut coke with something dangerous? I mean, I don't want any complications just because I used something mixed/bad and end up terribly sick.
No coke, no problems. I used this motto five years back when I was on the verge of becoming seriously addicted. I have been going from a party to a party, sniffing, eating and smoking anything I could get my hands on. Until one night, I almost died because of some bad stuff. I cant even remember what I used or who gave me that, I only know that I ended up in hospital. I stopped, somehow. To answer your question, there is a possibility that some dealers are cutting coke with something just to earn more money. Whether the added substance is dangerous, I do not think they care.
