I suppose because I didn't get in with a drinking crowd til grade 11 (16 yo) myself (whereafter I drank in moderation but didn't get drunk, to the disgust of my mostly more heavily drinking 15- and 16 yo friends) I AM rather shocked that you'd be feeding alcohol to a 15 yo. (Especially a guy who has some self-control problems like this one.)

On the other hand, a legal response proportionate to the crime should be something on the order of a moderate fine, and the hysteria that's led to this being a NUCLEAR situation, as Dakota rightly states, is one of those state overreactions that drives successive generations of fundamentally law-abiding, non-criminal humans to being hardened, routine lawbreakers. It doesn't really matter how heavy the penalty is in such cases: for example, for nearly 30 years in Mongolia, to be caught with religious paraphernalia was a sure ticket to death in a stalinist concentration camp, yet when the country democratized, it turned out that large numbers of families had meticulously saved all sorts of religious objects. When a heavy penalty only signals that social-engineering idiots are at the helm, it obliges people merely to be clever, not compliant.

There may be some teens in North America who never drank illegally, but I can't say I've ever met one, excepting Muslims. (Maybe I'm just trash?) It's dangerous and potentially destructive, but it happens.

Don't do it, but if you do, don't let the gulag get you for it, that's all. Think survival.
