By the way, Mr. Clandestine, there are people who use heroin, meth, and crack recreationally, but on occasion. So they don't become physically addicted. Yes, there are people who do these hard drugs without becoming addicts. Out of 6 billion people in this world, I don't think you can deny that. So, you saying that "Heroin can, and will, do this" is a bit over the top. Although, I can't deny that it has a high potential of doing what you say. Just saying that it "will" unconditionally do that is an exaggeration.
