Question about heroin?
I have a question? Does heroin come in rock form or powder form? Because I was writing a little screenplay just for fun, like a creative writing kind of thing and in my story the main character was a recovering heroin addict. In the story, I wrote down that heroin came in vials in rock form but in this movie the heroin came in a powder form so, which is it? I want to know if this is currect or not? Please help if anyone knows about heroin. Thanks.
