It works in a totally diffenrent way to ecstasy. As for people putting heroin and coke in pills. What a load of crap. If I was manafacturing pills I would not go to the trouble of buying other illegal substances to put in it. Why would someone want to mix a more expensive drug with a drug they are making at probably 100th of the price.
Dealers dont want to get people addicted like that.
If the quality of the pills is good the dealer knows peolple are going to keep coming back to him. If he sells some dodgy ones word soon gets aroung and he's left with a bag of pills he'll find hard to sell. I alway buy off dealers I know and have sold me good pills before. However the initial rush when u r coming up can be really hadr and can make u sick and paniky if u have never done it b4. Not being able to pee.
