1. Be prepared to deal with the pressures that come with the territory. Not everyone will be as smart as you. There will be some who will decide to drink or use drugs and try to encourage you to do the same. Don't be caught off guard and say yes to something you'll regret. Be ready to say no or walk away. Humor often works in these situations and once they realize you're not going to join them, they'll leave you alone.
2. Plan something fun and stick to the plan. Prom is all about the memories. If you and your friends plan something exciting, off-the-wall and memorable, no one will want to leave to drink or use drugs. You can go for coffee, grab a late night bite or even something silly like karaoke. By making firm plans, everyone will have a say and you'll look forward to just being together. This will be worth far more than one night of bad choices.
3. Be a leader for others to see. Just like peer pressure works to get others to drink or use drugs, it can also work in a positive way. If you're having a blast and are the life of the party and you're staying sober, others will take notice. Show them it's possible and actually better to have a good time without being intoxicated. You'll have a great time with no regrets.
4. Stay with your friends all night. It's fine to go to a party on prom night. For most, that's part of the experience. Just be sure you and your friends take care of each other. Watch your drinks so no one can slip you something and help each other stick to your decision to stay safe and sober. If something does happen, you'll be in control of your senses and able to get home safe and sound.
5. Drive carefully. Weekends and especially Prom night are the worst times to be on the road. There are more drunk drivers at that time. Be sure to drive carefully and know where you're going. Have a charged cell phone available in case of an emergency and take extra precautions like pausing another second at a red light or stop sign.
