Nearly half of undergraduate drug users name marijuana as their primary drug, yet only a small slice of college students who need opioid treatment report receiving medication for opioid use disorder. At the same time, 27% of universities say they offer peer-led substance use prevention workshops and 42% of treatment centers report waiting lists, leaving many students to miss help. These contrasts between what campuses offer and what students actually receive set the stage for a closer look at the latest college student drug use picture.
Key Takeaways
- 29% of college students who needed help for drug use did not receive treatment (NSDUH college students tabulation)
- 0.7% of college students reported receiving medication for opioid use disorder (MOUD) in the past year (NSDUH 2021, college students tabulation)
- 2,000+ colleges participated in the American College Health Association’s surveys in 2022 (ACHA-NCHA participation)
- 10% of college students reported perceiving cocaine as “great risk” (2022 survey year)

- 14.8 million Americans had an alcohol use disorder in 2022 (SAMHSA)
- 42% of treatment centers reported they have waiting lists for substance use treatment (2023).
- 17.3% of students who experienced substance-related harms reported receiving no services in the past year (2019).
- 7.6% of U.S. college students reported using cocaine in the past year (2019).
- 29% of clinicians reported that confidentiality policies were unclear to students, reducing likelihood of seeking help (2020).
- 11% of students reported fear of disciplinary consequences as a barrier to substance use help (2022).
- 2.3x reduction in binge drinking odds among students at campuses with integrated screening and brief intervention programs (systematic review effect estimate).

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
