Dramatic drop in marijuana use among U.S. youth over a decade
Reported declines in U.S. teen marijuana use over the past decade prompt debate about what’s driving the shift, especially as legalization for adults has expanded. Commenters point to broader trends of reduced adolescent risk-taking—less alcohol, sex, and driving—along with increased screen time, harsher economic pressures, and changing social norms that make weed feel less “cool” and more like a regular consumer product. Others question the reliability of self‑reported survey data and note unresolved concerns about cannabis health risks, potency, and the role of black markets under high taxation.
Explanations for Decline in Teen Marijuana Use
- Many argue legalization made cannabis less “forbidden” and therefore less attractive as a rebellious act.
- Legal retail plus ID checks may reduce underage access by shrinking the traditional dealer network.
- Others think the decline fits a broader trend of reduced teen “risk” behavior (drugs, alcohol, sex), not uniquely tied to weed laws.
- Some suggest teens are simply busier (sports, homework, scheduled activities) and have less unsupervised time.
Role of Legalization and Markets
- Debate over whether legal prices undercut the black market: some states report very cheap legal weed; others say taxes and compliance keep legal prices high.
- Even where black markets persist, convenience and safety of legal shops reduce incentives to buy illegally, especially for low-volume users.
Generational Attitudes and Culture
- Several Gen Z/Zillennial posters say drugs and alcohol are viewed more like neutral “consumables” (like coffee), not identity or status markers.
- Substance use is less of a social milestone; being sober isn’t stigmatized.
- Some link this to broader self‑improvement culture (gym, mental health, “you do you”), mixed with rising anxiety and loneliness.
Measurement and Skepticism
- Questioning reliability of self‑reported teen drug surveys; mood, survey context, and wording could skew results.
- Others counter that long‑term trends are still meaningful even if absolute levels are off, though this assumption is challenged.
Broader Youth Behavior Shifts
- Teens reportedly drive less, have less sex, drink and smoke less, and sometimes even skip dances; phones and online life are seen as major substitutes.
- Social media and pervasive cameras make public intoxication riskier for one’s “brand,” discouraging visible partying.
- Some worry youth are abstaining from all experiential behaviors, with loneliness and depression up and suicide as a grim outlier to the downward trend.
Health Risks, Potency, and Substitutes
- Cited research about adolescent brain development, psychosis risk, and immune effects leads some to welcome the decline.
- Multiple comments say modern cannabis is much stronger, making bad experiences more likely and pushing casual users away.
- Speculation that increased use of prescribed stimulants/SSRIs may reduce self‑medication with marijuana, but this is noted as unclear.
Language, Law, and Severity of Punishment
- Extended debate over separating “drugs and alcohol,” with some arguing it unjustifiably normalizes alcohol.
- Strong disagreements about harsh drug laws (e.g., Singapore’s death penalty for trafficking cannabis) versus the social harms of legal alcohol.
