===== 1. No Clear Increase in Teen Use; Many Measures Show Declines =====
'' U.S. national surveys — including the Monitoring the Future (MTF) and CDC’s Youth Risk Behavior Survey — show that marijuana use among teens has ''declined* or remained stable nationally, even as more states legalized adult recreational use from 2012 onward. Past-month use among 8th, 10th, and 12th graders has dropped significantly over the past decade.

* Measured declines nationally include: - 8th graders: ~7.2% → ~4.3% (past-30-day use) - 10th graders: ~17.6% → ~9.5% - 12th graders: ~22.6% → ~16.2% These figures span roughly 2011 to 2024 — a period covering much of the legalization rollout.

* Self-reported ease of access for marijuana among teens has also dropped over that period, suggesting less perceived availability.

What this suggests: On national datasets, legalization has not corresponded with overall increases in adolescent marijuana use — and in many cases, use has declined.
