Illicit Drug Use - Youth in New Hampshire

New Hampshire

Substance use often begins during adolescence, with the most commonly reported reasons for substance use being: seeking to feel calm, experimentation and other stress-related motivations. Substance use during adolescence has a significant and lasting impact on health and well-being, increasing risk of the following: 

• Impaired physical and cognitive development. 
• Other risky behaviors, such as impaired driving and unprotected sex.
• Other health concerns in adulthood, including heart disease and high blood pressure.
• Becoming addicted or continuing to misuse substances later in life.

Substance use among adolescents in the United States is currently near a historic low; however, 31.7% of 12th graders reported using illicit drugs in the past year in 2025. More than a third of those who used substances reported using two or more, often at the same time, which increases the risk of overdose and long-term health problems.

According to data from the Substance Abuse and Mental Health Services Administration (SAMHSA), the prevalence of illicit drug use is higher among:

• Youth ages 16-17 compared with those ages 12-13 and 14-15; the prevalence is higher with each increase in age group. 
• Non-Hispanic white, non-Hispanic Black, non-Hispanic American Indian/Alaska Native and Hispanic youth compared with non-Hispanic Asian youth.
• Youth who experienced a major depressive episode in the last year compared with those who did not.

Nonmedical drug use can be prevented and treated. Interventions that focus on addressing stress and mental health conditions could reduce motivations for substance use among adolescents. SAMHSA offers evidence-based programs and resources for parents, schools and primary care providers. The National Institute on Drug Abuse also provides information regarding evidence-based prevention strategies designed to meet the needs of people at different stages of life and in different contexts, including family life, school, health care and community.

Community-school partnerships can help young people feel supported and connected, provide important health education and reduce risk factors for substance use. Programs such as Communities That Care and PROmoting School-community-university Partnerships to Enhance Resilience (PROSPER) have demonstrated positive results using a combination of evidence-based prevention education and substance use treatment services. 

When prevention is no longer an option, there are evidence-based treatment programs. Treatment often requires lifelong management. SAMHSA’s treatment locator can help individuals find state-licensed providers specializing in substance use disorders, and their Evidence-Based Practices Resource Center collects guidance and strategies for treatment facilities and medical practitioners providing substance abuse treatment and recovery.

Healthy People 2030 has several objectives to reduce illicit drug use among youth, including:

• Reducing the proportion of adolescents who used drugs in the past month.
• Reducing the proportion of adolescents who used marijuana in the past month.
• Increasing the proportion of adolescents who think substance abuse is risky.
