When I heard your advice to a parent to give more supervision to a teenager using drugs, it reminded me of an experience I had many years ago while teaching high school.One of my students asked to come in at the lunch hour to catch up on school work and raise his grade. I was always happy to help my students do that. I had to sign the time he arrived and left for his parents. As we chatted, I found out he had gotten into trouble with drugs. His parents decided he needed their full supervision. They dropped him off at the beginning of school, picked him up at the beginning of lunch, dropped him off at the end of lunch, and picked him up at the end of the school day. They told him living in their home was a privilege that he needed to earn. He was living in a tent in the backyard, trying to earn his way back into the home. I was so amazed by his parents. I told him he was fortunate to have parents that cared enough to help him get his life back on the right track. He was in total agreement. I learned you need to do what it takes to get your child's attention. If you need to go to extreme measures, then do it. Kudos to those parents! 

Thank you,
