It's difficult to know if the changes you're seeing in your child are related to drug use or depression, or are part of the identification crisis that's typical of many adolescents.

You probably fear that if you confront them with your concerns, they'll bolt out of the house and run away, and cut all ties to home. If you say nothing, taking on the "don't ask, don't tell" approach, you take the chance that they'll slip further from the goals and dreams you hold for them and the ones you thought they held for themselves. By being patient and allowing them to move thorough this period, they could snap out of it. Do you want to leave it to chance?
