The current federal status
Under the Controlled Substances Act of 1970, marijuana is classified as a Schedule I drug, defined by the federal government as having a high potential for abuse and no accepted medical use. That places it in the same legal category as heroin and LSD, and stricter than cocaine or methamphetamine, which are Schedule II. Federal law prohibits its production, distribution, and possession, though enforcement priorities have shifted across administrations.
The state-federal patchwork
As of 2024, 24 states and the District of Columbia have legalized recreational marijuana for adults, and 38 states allow medical use under a doctor's recommendation. Because federal law still bans the drug, businesses operating legally under state law often cannot access federally regulated banking services, and users can face complications with federal employment, housing, or firearm purchases.
The rescheduling process
In 2024, the Drug Enforcement Administration began a formal rulemaking process to move marijuana from Schedule I to Schedule III, a category that includes substances such as ketamine and anabolic steroids. Rescheduling would not legalize recreational use but would loosen research restrictions and allow state-licensed cannabis businesses to deduct ordinary business expenses on federal taxes. The rule has not been finalized and is subject to administrative review.
The case for federal legalization
Supporters argue that legalization would align federal law with public opinion — a 2023 Gallup poll found 70 percent of U.S. adults favor it, up from 12 percent in 1969 — and end the conflict between state and federal rules. The Congressional Research Service has estimated federal tax revenue from a legal market could reach roughly $8.5 billion a year. Advocates also point to racial disparities in past marijuana arrests and argue that regulated sales would reduce the illicit market.
The case against federal legalization
Opponents cite data from the National Institute on Drug Abuse linking heavy marijuana use to cognitive impairment and mental-health risks, particularly among adolescents whose brains are still developing. Some law-enforcement groups and public-health organizations warn that broader availability could increase impaired driving and youth access. Critics also question whether projected tax revenues would offset public-health, regulatory, and treatment costs.
How federal change could happen
Congress can change federal marijuana law by passing legislation, such as full descheduling or a bill allowing states to set their own policies without federal interference. The executive branch can act on its own only within the limits of existing law — for example, by rescheduling through the DEA or by directing federal prosecutors to deprioritize certain cases. Courts may also weigh in on conflicts between state programs and federal statutes.
What voters are being asked
The question of federal legalization involves trade-offs between federalism, public health, criminal justice, and tax policy. Voters weighing in are essentially deciding whether marijuana should be treated more like alcohol and tobacco — legal, regulated, and taxed at the federal level — or remain a federally controlled substance, with states continuing to experiment within the limits set by Washington.
