How can you prepare to resist the peer pressure to drink

It is impossible to avoid thinking about alcohol, as friends will bring it up to you. If you do avoid thinking about alcohol, you will not be prepared to come up with valid excuses to turn down alcohol, and may succumb to peer pressure.

Pretending to drink will land you in the wrong crowd of people who actually do drink. The crowd may offer you actual alcoholic drinks that you will be pressured to drink, or you will risk being outed as a pretender.

Hanging out with peers who drink will make drinking seem more normal as you hang out with them more. 

The best way to resist the peer pressure to drink is to think of reasons for not drinking. This way, you can prepare yourself by thinking of good answers and reasons for not drinking ahead of time and convince your friends to not pressure you into drinking.
