Kids should be taught to analyze a situation and make their own decision, whether their peers agree or not. If kids know the facts about alcohol and other drugs, they will know if what peers tell them is true or not. Have something else to do. Have an activity or a place to go. Be prepared for other pressures.
Some peer pressure is in the form of teasing at first.
Keep it simple. Help kids understand that they don't have to explain why they don't want to do something. They don't need to explain their reasons to anyone. Avoid the situation. Teach kids to stay away from people or places associated with alcohol or other drugs.
