<p>I don’t think it is inappropriate to call another parent and let him/her know that there was an incident with alcohol that occurred recently and that you and other parents are taking the episode seriously. I think it’s a danged good idea. You may be surprised at the response. I actually got a couple of parents who told me that they were going to be closing their eyes to any alcohol that might make its way to the house, but they would make anyone intoxicated stay the night there or get a parent to pick him up. Not at all reassuring to me, and my son did not go to such parties or get togethers. I also wanted it clear that the parents knew that I was very concerned about substance abuse and if my kid was involved in any such activity, I wanted to know about it. Sometimes, people don’t want to deal with parents they do not know and will turn a blind eye to this business.</p>
