When I was in Ninth Grade before Purim My Rebbi ( an established Posek) got up and gave a shiur on Drinking. Basically he was very firm it stating whether or not someone drinks at the age of thirteen is between him and his parets and all his talmidim should discuss the issue with thier Parents.
He then went on to explain how even if one Drinks there is a “safe” way of drinking and a non-safe way and he gave a detailed guide as to what practices must be avoided at all costs (mixing, drinking on an empty stomach etc..) It is one shiur I have never forgotten and I still tell over many parts of it to others.
(Rabbi Yossi Rosenberg happens to have an excellent article about drinking in this weeks Yated)
