Youth cannabis use in the United States has dropped to its lowest level in more than three decades. Data from the Centers for Disease Control and Prevention (CDC) shows that the share of high-schoolers who currently use cannabis has fallen by roughly 60 percent over the past ten years. That decline happened while nearly half of all U.S. states regulated adult-use cannabis markets. This matters because one of the loudest arguments against legalization was that it would push more teenagers toward cannabis. The government's own numbers do not support that claim.
What the CDC Data Actually Shows
The figures come from the CDC's Youth Risk Behavior Surveillance System (YRBS). The YRBS is a national survey that tracks health-related behaviors among U.S. high-school students. In this survey, a current cannabis consumer is a student who reports using cannabis at least once in the previous 30 days.
According to the YRBS Explorer website, the share of high-schoolers who fit that definition fell about 60 percent over the past decade. The rate is now lower than at any point in roughly 30 years. The cannabis reform group NORML, the National Organization for the Reform of Marijuana Laws, publicized the data.
The timing is what stands out. The decline coincides with the spread of adult-use legalization, meaning laws that allow adults, usually 21 and older in the U.S., to legally buy and possess cannabis through licensed, regulated sales. Nearly half of U.S. states now have these markets.
"Sensational claims that adult-use legalization laws are linked with greater marijuana use by teens are simply not backed by reliable data." — Paul Armentano, NORML Deputy Director
Armentano added that the findings "ought to reassure lawmakers that cannabis access can be legally regulated in a manner that is safe, effective, and that does not inadvertently impact young people's habits."
Other National Surveys Show the Same Pattern
A single dataset can be an outlier. Several independent sources showing the same result is much harder to dismiss. The CDC's finding that U.S. teen cannabis use is at a historic low matches results from at least three other major sources:
- University of Michigan: Its long-running Monitoring the Future survey tracks drug use among American students. It also reports youth cannabis use at historic national lows.
- SAMHSA: The Substance Abuse and Mental Health Services Administration is the federal agency that runs the National Survey on Drug Use and Health. Its data points in the same direction.
- Marijuana Policy Project: In an analysis published last year, this policy organization found that teen marijuana use declined in nearly every state that has legalized and regulated adult-use cannabis.
These surveys use different methods, different sampling approaches and different organizations to run them, yet they reach the same conclusion. That kind of agreement is what gives a trend credibility.
It is worth being precise about what the data does and does not show. Falling use alongside legalization does not prove that legalization caused the drop. It does, however, directly contradict the prediction that regulated adult markets would drive teen consumption up. For policymakers weighing reform, that distinction is central.
Germany Reports a Similar Trend After Legalization
The pattern is not limited to the United States. Germany legalized adult-use cannabis in April 2024, and its first major post-legalization youth data shows a modest decline rather than a rise. The German Federal Institute for Public Health ran its Drug Affinity Study 2025, a recurring national survey on substance use among young people. It questioned 7,001 people aged 12 to 25 between April and July 2025, then compared the results with a similar study from April to June 2023.
| Metric (ages 12–17) | 2023 | 2025 | Change |
|---|---|---|---|
| Consumed cannabis in past 12 months | 6.7% | 6.1% | −0.6 points |
| Regular use (more than 10 times in past 12 months) | 1.3% | 1.1% | −0.2 points |
The changes are small, but they move in the same direction as the U.S. data. Regular use among adolescents also slipped, which is notable because frequent use is the main concern for public health experts.
A separate study found that German legalization was not associated with changes in heavy use. Taken together, the early German results suggest that regulated access for adults did not spill over into higher youth consumption. That is the same conclusion U.S. surveys have reached.
Why Regulation and Falling Youth Use Can Coexist
Many people assume that legal cannabis means easier access for teenagers. Researchers and reform advocates often point to several reasons why regulated markets may have the opposite effect:
- ID checks at the counter: Licensed retailers lose their licenses if they sell to minors. Street dealers face no such risk and don't check ages.
- A shrinking illicit market: As adults shift to legal stores, fewer unregulated sellers remain who are willing to supply young people.
- Less "forbidden fruit" appeal: When cannabis becomes an ordinary, regulated adult product, some of its rebellious appeal fades.
- Better public education: Legal frameworks often pair sales with prevention campaigns and age-specific messaging.
For us at Shottas®Seeds, this aligns with what we have always believed. Responsible regulation works. We are built by growers for growers, and our audience is adults aged 18 and over in places where cultivation is legal, or collectors. Transparency and accountability are not obstacles to a healthy cannabis culture. They are its foundation.
The data now backs that up. Legal, regulated access for adults and declining youth use can go hand in hand.
Frequently asked questions
Has teen cannabis use increased since U.S. states began legalizing?
No. CDC data shows the share of U.S. high-schoolers who currently use cannabis fell about 60 percent over the past decade and is now at its lowest level in roughly 30 years. During the same period, nearly half of all states introduced regulated adult-use cannabis markets.
What does "current cannabis use" mean in youth surveys?
In the CDC's Youth Risk Behavior Surveillance System, current use means a student reported consuming cannabis at least once during the 30 days before the survey. This standard measure lets researchers compare recent use across years, states and demographic groups in a consistent way.
Did youth cannabis use rise in Germany after legalization?
Early data says no. Germany's Drug Affinity Study 2025 found that past-year cannabis use among 12- to 17-year-olds fell from 6.7 percent in 2023 to 6.1 percent in 2025. Regular use in that age group also dropped slightly, from 1.3 to 1.1 percent.
Does this data prove legalization reduces teen cannabis use?
Not on its own. The surveys show that youth use declined while legalization expanded, which is a correlation, not proof of cause. However, the findings clearly contradict predictions that regulated adult markets would increase teen consumption, and they are consistent across several independent national surveys.
Why might legal cannabis markets limit access for minors?
Licensed retailers must verify customer age and risk losing their licenses if they sell to minors. Illicit sellers have no such obligation. As adults move to legal stores, the unregulated market shrinks, which can reduce the number of sources willing to supply cannabis to teenagers.
