If I may add my .02, I was just like your daughter at that age. Lying to my parents, sneaking out, hanging out with drug users - and I was still a very good kid overall. I got over it, with some heavy-duty policing by my parents. They never let up, and nor should you. They were very worried, but deep down they knew it was just a phase. It took me a long time to grow up (hell, I'm still growing up!), but I knew all along what was right, and that these people were just a diversion from the boring and mundane life of the "normal" kids. Maybe some extracurricular involvement in some highly creative outlets would help - you know, with creative, funky kids (who are also on the straight and narrow).
