Surround yourself with friends who have similar interests, principles, and standards as you. These friends are less likely to put you into compromising situations and will stand beside you if you both end up being pressured by peers. Having friends you can count on allows you to do other fun things if you have to walk away from peer pressure situations. Support your friends. Be the person who helps stand up when a friend is in a situation they might find difficult. Are your friends starting to do more and more stuff that you don't want to do? Have they changed since you first became friends? Ask yourself why you are friends with them in the first place. Maybe you can talk to them about their new habits. Sometimes people just want to explore new things; other times they do those things because they feel stressed out by something else. Try to talk to a friend with this approach: "Hey, I noticed you've been doing a lot more smoking/drinking lately...that's fine and totally your choice, but what's up? You never used to do that stuff. Is everything ok?" Sometimes, you might have to break up with your friends. This can be really hard to do, but if your friends are constantly pressuring you to do stuff you don't want to do, maybe it's better to move on. If they don't respect your opinions and choices, they're not really you're friends in the first place. If you find yourself surrounded by people who participate in activities you feel uncomfortable doing, make new friends. If you started pursuing new interests, try to find new friends who have those same interests. Look for people at parties who are not drinking, doing drugs, smoking, or having sex. Talk to people in your classes who may have similar interests. There are other people who are avoiding the same things you are. Don't allow yourself to get into situations where you might be pressured. Be confident enough to not go to a party you know will have tons of alcohol and drugs, or go back to an empty house with a guy or girl you're not ready to get intimate...
