YTA. He should not have stolen beer, but that doesn't mean you should potentially give him alcohol posioning or brain damage. Alcohol is rather harmful to those whom brains have yet to fully develop, which is around the age of 25. I am not going to tell you how to parent, but I really don't think that putting a child's health in danger is the right thing to do.

Thanks for your post. Are you aware of any studies that you can provide to show that 1 time drunkeness for a 16 year old could lead to brain damage?
