The drinking age in MA, and elsewhere, is 21, and I can't imagine there is none of that going on at the colleges except for possibly of-age seniors. With the extension to tobacco, the fake id business is just going to proliferate even more. And sadly, those who do imbibe, and get caught, will technically be criminals.
I just wonder if people who actually do wait 'til age 21 to have their very first drink (or tobacco product), then go overboard with their new found liberty, or actually have gained the maturity to not overindulge, or even not try anything then at all.
