By Federal Data Reveals Decline
The Substance Abuse and Mental Health Services Administration published a report last month detailing national substance abuse treatment trends. This new federal data shows that the percentage of Americans seeking drug treatment for marijuana has declined steadily for the last half-decade. Specifically, admissions fell approximately 20 percent between 2020 and 2024.
These findings contradict recent media narratives suggesting a rise in problematic cannabis use. The data indicates that fewer individuals are entering treatment programs for marijuana-related issues over time. This trend holds true despite surveys showing a greater percentage of adults choosing cannabis products.
Alcohol use disorder remains a significantly larger driver of treatment admissions than cannabis. More than four times as many people are admitted to treatment annually for alcohol use disorder. This disparity highlights the relative scale of cannabis treatment needs compared to other substances.
Criminal Justice Drives Admissions
The Treatment Episode Data Set reveals that cannabis-related treatment admissions are largely driven by the criminal justice system. Admissions are highest in jurisdictions where cannabis possession remains illegal and arrests are prevalent. These specific states include Alabama, Florida, Georgia, Iowa, Indiana, and Texas.
Police in those states made over 70,000 marijuana possession arrests in 2025.
Judges in these jurisdictions often offer defendants the choice of attending a substance abuse treatment program in lieu of jail time. This option is available regardless of whether the defendant exhibits signs of problematic cannabis use. Consequently, many admissions are mandated by the court rather than driven by voluntary health concerns.
Legal States Show Low Admissions
States where cannabis is legal and possession arrests are minimal have among the lowest number of marijuana-related treatment admissions. Massachusetts and Washington are cited as examples of jurisdictions with these low admission rates.
Problematic cannabis use, or cannabis use disorder, is defined by a pattern of use leading to difficulties. A person must meet two out of 11 possible criteria to be diagnosed with this condition. These diagnostic criteria have been revised multiple times over the past four decades.
The current criteria include experiences such as withdrawal and tolerance, which are associated with habitual use. No exceptions are made for patients who regularly consume cannabis for therapeutic purposes. These medical users are often improperly classified under the current diagnostic standards.
