People don't have to worry about drinking, really. In my house, for example, there's a girl who doesn't drink - there's no pressure on her to drink, and for her birthday we just did non-drink related stuff (obviously!). There's also no real drinking culture within my American football team - well, most people drink, but there are players who come to our socials who don't drink, and there's no pressure on them to drink anything.
There aren't just hordes of people, with beer bongs, forcing all and sundry to get ~crunkkkkk~ at uni... and I don't know many people who take drugs... just to counter some of the, "everyone just drinks/takes drugs/are stoners/wasters" stuff peoeple are coming out with. All kinds of people can be happy, imo.
