Legal Cannabis Generates $28.4B in U.S. State Tax Revenue

American states that have legalized recreational cannabis have already collected over $28.4 billion in taxes on its sales, according to a new report from the Marijuana Policy Project (MPP), one of the largest organizations lobbying for cannabis law reform in the US.

While 2025 was a record year in this regard, there are signs that this cash flow from legal cannabis sales has reached a ceiling.

From two states to almost half the country

It all started in 2012, when Colorado and Washington became the first states to vote to legalize recreational cannabis for adults over 21. The first legal dispensaries opened two years later, in 2014.

Today, 24 states and Washington, D.C., have legalized recreational cannabis. Of these, only Virginia and the capital city itself do not yet have regulated, taxed sales—the remaining markets are fully operational. Over the past 12 years, this has contributed to the aforementioned $28.4 billion in legal cannabis tax revenue.

Record-breaking 2025

In 2025 alone, states will receive more than $4.57 billion in recreational cannabis taxes—the highest single-year total since legalization began. This compares to $4.4 billion the year before.

The scale of the legal cannabis market is best seen at the top:

seven states raised over $200 million each in 2025,
three of them —California, Illinois, and Michigan—exceeded 500 million,
and California alone collected over a billion dollars in a single year and over $7 billion since sales began in 2018.

The report also shows how rapidly this market has grown nationally. Between 2018 and 2021, annual revenues jumped from around $1.3 billion to nearly $4 billion—largely thanks to the entry of large states like California.

What is this money going towards?

States allocate legal cannabis revenues very differently. Some go directly to general budgets, while others are allocated for specific purposes. The list of beneficiaries includes:

Medicaid and health care,
education and school construction,
housing and roads,
early literacy and peer violence prevention programs,
mental health and treatment of alcohol and drug addiction,
veterans services,
nature conservation and vocational training,
costs of expunging past cannabis convictions,
reinvestment in communities most affected by the “war on drugs.”

In states with mature legal cannabis markets, recreational cannabis taxes typically account for between 0.25% and 1.5% of the state budget. In several states, cannabis already brings in more than alcohol taxes.

“At a time when pressure is mounting on state budgets, recreational cannabis taxes provide relief,” says Adam J. Smith, executive director of the MPP. He adds that legal cannabis markets have become “powerful economic engines,” creating thousands of jobs. However, he points out that excessive taxation can be self-defeating: excessively high prices in legal stores drive customers back to the black market—unregulated, unsafe, and untaxed.

Smith also emphasizes an argument that, for MPP, is more important than the money itself: the end of prohibition spared hundreds of thousands of people the trauma of arrest and prison. And according to data cited by the organization, the percentage of teenagers using cannabis in most legal states has actually declined.

The Growth Ceiling: A Lesson from Colorado

The report isn’t all triumphant, however. The clearest warning comes from Colorado, a pioneer that has raised over $2.8 billion since launching in 2014. Legal cannabis revenues there continued to grow until 2021, when they peaked at $396 million. Then they began to decline, reaching an estimated $221 million in 2025.

There are several reasons. When neighboring states also legalized cannabis, Colorado lost its previous advantage in cannabis tourism and cross-border sales. This was compounded by falling prices: rising production and increasingly fierce competition meant that supply outpaced demand.

This is a broader pattern. Early revenues after legalization can be high, but over time, growth slows and the market stabilizes at a lower level. As the report warns, “taxes on a single product won’t solve all the state’s financial problems. But they help tremendously.”

Signs that the legal cannabis market is maturing also came from another source. A separate analysis by Vangst and Whitney Economics found that in 2025—for the first time since recreational markets began in 2014—national cannabis revenues would decline year-over-year.

What these numbers don’t show

The $28.4 billion figure almost certainly understates the industry’s true impact on public finances. The report deliberately excludes :

taxes on medical cannabis,
local (municipal) taxes on cannabis,
fees for licenses and applications for companies,
income taxes paid by industry employees,
federal taxes and broader supply chain effects.

It’s also worth remembering that revenue alone isn’t a measure of policy success. High taxes can mean greater consumption, but they also depend on rates, consumer behavior, competition, and regulatory design. Excessively high rates keep the black market alive. Conversely, states with lower taxes earn less per transaction but attract more customers to the legal market.

However, one thing is clear from the report: the legalization of recreational cannabis has become a real, significant source of public money in the United States.
