Teenage alcohol abuse can progress through several stages, starting with experimentation and learning tolerance levels. For most teens it becomes social use, where drinking is planned and associated positively. However, for some it advances to abuse where amounts increase, activities are replaced by drinking, and harmful consequences occur but use continues. The most severe cases become addiction, where lifestyle revolves around alcohol and one is incapable of quitting. Teenage alcohol abuse can result in behavioral, physical, and memory problems, as well as legal and health consequences that disrupt normal growth and development.
