Over the last 15 years, researchers have found several paths that influence substance use and substance abuse by adolescents. The addicting power of some of the substances plays a major role in converting some experimenters into regular users. How a family, school district, and neighborhood handle substances also plays a role in reducing or encouraging substance use. Approximately, 25-30% of teens have tried tobacco by the time that they are seniors in high school, and 35% of those who try become regular smokers with difficulty kicking the habit. Over 70% of seniors have used alcohol at least once, with 25% reporting they get drunk at least once a week. About 20% have tried marijuana by the time they graduate and 10-15% of these teens are addicted to marijuana.
