While parents may think tweens (aged 10-14) need less adult supervision when they are not in school, researchers found that certain coached extracurricular activities can help prevent tween smoking and drinking. The study found that team sport participation with a coach was the only extracurricular activity associated with lower risk of trying smoking compared to none or minimal participation. Participating in other clubs was the only extracurricular activity associated with lower risk of trying drinking compared to none or minimal participation.
