I have a 18 year old daughter that smokes pot a lot. She is a good student and has a job. She is a "mouthy" child but always has been. She is my middle child. She made a complete turn around this year and said that she felt that her friends last year were fake and this is who she really is. She has no desire to stop. My husband doesn't think this is a big deal but I have strong concerns. She will be leaving for college in the fall which is a time that kids tend to totally let loose. I am not sure what to do..
