I really don't see why someone "needs help" just for bringing alcohol to school. Yeah, it was dumb, but it's not like he hurt anyone.
It's not so much the action, but the reason for why it was done. Rational 15-year-olds concerned about their well-being don't knowingly carry a 20 oz bottle of vodka to high school. There are numerous reasons for why someone might do this, and considering the fact that it's quite easy to just wait until school gets out, none of the reasons are particularly good news.
