If her grades stay up and she becomes a little more extroverted, there really isn't much danger that you need to focus on. Also, trust your daughter. If she says she isn't smoking weed, she may not be. Maybe her friends were, or maybe she's stopping. Either way, if you want to talk to her, remember that it's her life. Her decision. Don't treat her like a kid or a junkie, treat her like a daughter and a trusted ally. Hope this helps. :) ... View more
