I have a few questions. I'll give you the story first. I've taken in a friend of a friend so I can get him off the street. He told me up front that he's a recovering crack addict. I told him that if he ever brought drugs into this house, that he would no longer be welcome here. Yesterday, I found an aluminum pipe with black resin :S I also found some rocks. He's trying to tell me that the aluminum pipe was for tobacco. I saw no tobacco, and I don't think there would be black resin if it were. I could be wrong--please, tell me if I am. As far as the rocks... is there anything I can do to tell if it's actually what I think it is? I want to be as careful as possible in figuring this out. Unfortunately, this is an area in which I'm not very educated. If anyone has had any experience with crack rocks, could you please share your wisdom with me? I'm feeling a little stuck here, and I want to make the right decision.
