Cannabis is still a Schedule I controlled substance under the federal Controlled Substances Act, and that has not changed as of this writing. The Drug Enforcement Administration proposed moving marijuana to Schedule III in May 2024, but the rulemaking is not final, so federal prohibition continues for possession, cultivation, and distribution outside approved research and a handful of FDA-approved medicines. This guide sorts out the status against three criteria: the text of federal law, the stage of the rescheduling rulemaking, and the practical effect on people who buy cannabis from licensed state retailers.
Why marijuana sits on Schedule I
The Controlled Substances Act of 1970 placed marijuana in the most restrictive category. Congress wrote the schedules, and the DEA administers them through its Diversion Control Division. To stay on Schedule I, a substance has to meet three conditions set out in federal statute: no currently accepted medical use in treatment in the United States, a high potential for abuse, and a lack of accepted safety for use under medical supervision. Federal agencies have applied all three to marijuana for more than five decades.
Cannabis Federal Law Review: Comparison Review
- Schedule I is the same tier as heroin and LSD, which is why federal penalties and research barriers track that category.
- Medical cannabis programs in dozens of states operate under state law, not federal law, which is the source of the conflict.
- Hemp and hemp-derived cannabinoids sit outside the drug schedules under the 2018 Farm Bill, though state rules on those products vary.
The rescheduling proposal: where it stands
The status question is really a rulemaking question. In August 2023, the Department of Health and Human Services sent the DEA a recommendation to move marijuana to Schedule III after a scientific review. The DEA then published a proposed rule in the Federal Register in May 2024, opened a public comment period, and referred the matter to an administrative law judge, where parties on both sides have been presenting testimony. A final rule has not been issued. Until one is, marijuana remains Schedule I.

What has already happened
- HHS completed its review and recommended Schedule III.
- DEA issued a proposed rule and took public comments.
- DEA administrative law judge hearings began in late 2024 and carried into 2025.
What still has to happen
The administrative law judge submits a recommendation, the DEA administrator decides, and a final rule would be published in the Federal Register. Any final order can also face legal challenges, which adds time.
If it moves to Schedule III: pros and cons
Pros
- Schedule III recognizes accepted medical use, which would align federal policy with state medical programs.
- Section 280E of the tax code, which blocks deductions for businesses trafficking in Schedule I or II substances, would stop applying to state-licensed cannabis operators.
- Research registration and supply requirements would loosen, which matters for clinical studies.
Cons
- Schedule III is not legalization. Possession and distribution without federal authorization would still be offenses.
- FDA oversight of cannabis products as drugs could bring labeling, dosing, and marketing rules that many state-legal brands do not meet today.
- Interstate transport would not become automatically lawful, so state-by-state supply chains would stay fragmented.
What would not change after rescheduling
- Recreational use would remain federally illegal for adults in every state.
- Taking cannabis across state lines, onto federal land, or through airports would stay a federal risk.
- Employers and federal contractors could keep drug testing policies in place.
- State licenses, testing rules, and possession limits would keep coming from your state regulator, not from the DEA.
If you buy cannabis in a legal state, here is the practical takeaway
For shoppers in states with licensed adult-use or medical markets, the sensible approach is to buy from a licensed retailer, keep the purchase in the state where it was made, and treat travel with cannabis as a federal matter rather than a state one. Licensed stores test products for potency and contaminants and follow state tracking rules, which is the layer of protection federal scheduling does not offer. If your state also allows home cultivation, stay inside the plant count and storage limits your state sets.
- Buy in person or from a licensed delivery service within the state.
- Do not carry cannabis into another state, even one where it is legal.
- Check your state regulator before assuming a hemp-derived product is covered by the same rules.
How to confirm the current status yourself
Three sources settle the question without speculation. The Federal Register shows the proposed and any final scheduling rule. The DEA Diversion Control Division publishes the current schedule lists. Your state cannabis regulator publishes what is legal where you live. If a headline says marijuana was rescheduled, check whether the item describes a proposal, a hearing, or a signed final rule.
Quick answers
Is cannabis legal under federal law?
No. It is a Schedule I substance, and Schedule III would still be a controlled category with restrictions.
Do state medical cannabis laws protect me from federal charges?
They do not change federal law. Appropriations riders have limited how the Justice Department can spend funds against state medical programs, but that is a funding restriction, not a legalization.
Are FDA-approved cannabis medicines available?
Yes, for specific products such as purified CBD for certain seizure disorders and synthetic THC medicines, which are handled through prescription channels rather than dispensaries.
