My 14 yr. old twin daughter started smoking pot about 9 months ago. She has always seemed a little less self assured than her twin, who incidentally has tried it, but has opted not to continue using. I think that one that is still smoking searched for peers that were less sure of themselves and a little lost, like her, and unfortunately she found a link with the pot smokers. She told me that she had quit smoking last fall, but about a month ago, she was smoking again - as was evidenced by her doing it in her bedroom with one of her friends while I was at work. I have told her that I cannot control who she hangs out with at school, but have told her that she is not allowed to hang out with this individual outside of school. I don't want to mandate that she not be able to hang out with these kids, because I know that it will force her that way even more, but this particular kid has parents that use, so there isn't any hope of this kid changing his ways based on home role modeling. Any suggestions on how to handle the peer situation?
