What are the facts about heroin? Not a lot is known because no one you know has ever done it. The only information out there is what is in movies and on television. For instance, heroin is sometimes called "the stuff." The amount you do is directly proportional to the amount of dirty laundry on the floor of your house.
If I were on heroin, I would not want people interrupting me by saying things like "damn this is some good stuff" or "are you going to go to the club tonight?" I would say, "I paid a lot for this heroin and the nice feeling only lasts for a half an hour* and I don't want you ruining it by saying things to me."
