Marijuana (cannabis) policy and use have changed dramatically in the last decade, with more states legalizing medical and adult-use programs and researchers tracking how legalization intersects with public health, enforcement, and the economy.
This post updates the most reliable marijuana statistics using primary and high-quality sources (NCSL for legality, SAMHSA for usage, and state revenue departments for taxes). Older numbers are included only when they provide useful historical context—and are clearly labeled by year.

Legalization by the Numbers (U.S.)
State policy varies widely, but NCSL’s tracked totals provide a clean, defensible snapshot:
- Adult-use (recreational): 24 states + D.C. allow or regulate non-medical cannabis for adults (as of Jun 26, 2025).
- Medical: 40 states + D.C. allow medical use of cannabis products (as of Jun 26, 2025).
Decriminalization is often defined differently across states (civil vs. criminal penalties; local vs. statewide). NCSL notes a “handful” of states with decriminalization approaches, including Hawaii, Louisiana, Mississippi, Nebraska, New Hampshire, North Carolina, and North Dakota.
How Many Americans Use Marijuana?
SAMHSA’s National Survey on Drug Use and Health (NSDUH) is one of the most important sources for U.S. cannabis prevalence. In 2024:
- Past-year use (age 12+): 22.3% (64.2 million people)
- Past-month use (age 12+): 15.4% (44.3 million people)
These are population-level estimates and are best used to understand broad trends over time rather than day-to-day changes.
Public Opinion on Legalization
Public support remains high for legalization in some form. Pew’s 2025 findings show:
- 54% say marijuana should be legal for medical and recreational use
- 33% say it should be legal for medical use only
- 12% say it should not be legal
Gallup’s October 2025 polling found 64% support for making marijuana legal (a separate question format), illustrating how results can vary depending on wording and survey design.
Economics: Sales and Tax Revenue
Because cannabis markets are regulated state by state, “U.S. sales” totals depend heavily on what’s included (adult-use + medical, which states, whether illicit sales are excluded, etc.). For consistent comparisons, it helps to stick with one forecasting firm over time.
- U.S. retail sales forecast: BDSA projected U.S. cannabis retail sales would total more than $38B in 2024.
- Global legal sales: BDSA said global legal cannabis spending was $36B in 2023 and forecast $58B by 2028.
For hard, audited government numbers, state tax departments are often the most reliable. Colorado’s Department of Revenue reports:
- 2025 Colorado marijuana tax revenue: $236,449,405
- Total-to-date (through 2025): $3,109,967,840
