My daughter is 43 & a very successful business woman and I'm very, very proud of her accomplishments. She grew up during the 70's/80's when drugs were the "thing to do". I remember some really awful fights with her because she thought she could "handle" things on her own. I didn't give an inch & I've never been sorry. It comes down to the fact that you love her & want her to be safe & you should follow your instincts on this.
