Illegal Drugs

Substance use is a concern among college students, driven by factors like newfound independence, less structured schedules, and social norms that normalize drinking and drug use within campus culture.
Yet this behavior can carry significant consequences, from declining academic performance, health complications, and threats to personal safety, making it a pressing public health issue. Below is a collection of resources focused on preventing drug misuse among college populations.
Scope
National Data
The 2023 National Survey on Drug Use and Health (NSDUH) report includes the following selected key findings1:
- 3.1% of people (8.9 million) misused opioids in the past year, which is similar to 2022 and 2021 (3.2% and 8.9 million, 3.4% and 9.4 million respectively).
- Between 2017 and 2020, hallucinogen use among college students more than doubled (4.1% compared to 8.6%).
- Approximately 5.6% of college students report past-year nonmedical prescription drug use with estimates ranging from 8.4% for prescription stimulants to 3.7% for prescription opioids.
- Among college students, rates of illicit drug use in the past year (other than marijuana) are estimated at about 20%.
- Common causes of substance use disorder in college students include coping with stress, peer pressure, genetics, and availability of drugs and alcohol.

Best Practices
Evidence Based Educational Programming
Effective educational programming includes the following elements:
- Increases students’ knowledge regarding the effects and the potential safety, health, social, academic and legal consequences of drug misuse
- Increases awareness regarding the signs and symptoms of drug misuse and dependency
- Assists students in evaluating their expectations regarding, and motivations for drug use
- Provides training in stress management, resistance skills and media literacy
- Assists students in exploring alternatives to drug use for socializing, destressing and celebrating
- Assists students in knowing how to help a friend in trouble
- Corrects misperception regarding norms for drug use at their institution
- Provides students with information about campus and community alcohol and other drug prevention, student assistance, and wellness and health promotion resources
Strategic Planning
Effective strategic planning and implementation of strategies at various levels of the socio-ecological model are necessary for drug misuse prevention.
Detection and Early Intervention of Substance Use Disorders
- Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an early intervention approach that is being used in colleges nationwide
- The SHADE (Self-Help for Alcohol and Other Drug Use and Depression) Computer Delivered Treatment may be a promising intervention to reduce substance use disorders. More information about SHADE.
