The short answer
Tetrahydrocannabinol (THC) is still a Schedule I controlled substance under the federal Controlled Substances Act, and marijuana remains Schedule I. That placement has not changed. What has changed is the process: federal health agencies completed a review and recommended Schedule III, the Drug Enforcement Administration proposed a rule to move marijuana to Schedule III, and the matter has moved through administrative hearings. The criteria used to sort the noise here are: whether an action is a recommendation, a proposal, or a final rule; which substance it covers, meaning botanical cannabis, THC as a molecule, or hemp-derived compounds; and whether it touches federal enforcement, state-licensed sales, or both.

Where THC sits in the schedules today
Schedule I
Botanical cannabis and THC fall under Schedule I, the category reserved for substances with no accepted medical use and a high potential for abuse under federal law. Federal registration, research, and business deductions all follow from that placement.
Schedule III
Schedule III covers drugs with moderate to low physical dependence and an accepted medical use, available only by prescription through a DEA-registered handler. That is the category HHS recommended and DEA proposed.
When Will Cannabis Be Rescheduled? DEA Status and Timeline
THC products already below Schedule I
Dronabinol, a synthetic THC sold as a prescription drug, sits in Schedule III. A prescription CBD product sits in Schedule V. Both exist because the FDA approved them through the new drug pathway, not because of a broad change to cannabis law.

How the rescheduling question reached this point
- October 2022: the President asked HHS and the Justice Department to review how marijuana is scheduled.
- August 2023: HHS completed its scientific review and sent DEA a recommendation to move marijuana to Schedule III.
- May 2024: DEA published a notice of proposed rulemaking in the Federal Register to transfer marijuana from Schedule I to Schedule III.
- 2024 into 2025: the proposal moved into administrative hearings, where both sides present evidence to an administrative law judge.
- Next step: a final rule, possible court challenges, or Congress acting on its own.
A proposal is not law. Nothing in the schedule changes until a final rule is published and takes effect.
What would change under Schedule III
Pros
- Federal recognition of accepted medical use, which is the legal hook for medical programs and clinical research.
- Relief from the tax rule that blocks deductions for businesses trafficking in Schedule I or II substances.
- Less friction in banking and payments, since Schedule I relationships carry extra risk flags.
- Lighter research registration compared with Schedule I studies.
Cons and limits
- It does not create a legal consumer market. A Schedule III drug needs a prescription and DEA-registered handlers, so adult-use sales would still be governed by state law.
- Tax relief is not uniform across business structures, and accountants would need to reassess filings.
- State criminal and civil rules stay in force, including state bans and license conditions.
- Moving product across state lines stays a federal problem.
What does not change
State licensing, age checks, possession limits, dispensary operating rules, product testing, and local zoning all come from state and municipal law. Federal rescheduling does not rewrite any of that. It does not open the door to anyone under 21 in states with adult-use programs, and it does not override an employer's testing policy or a landlord's rules.
Hemp-derived THC runs on a separate track
Delta-8 THC and other hemp-derived cannabinoids are debated under a different framework: the 2018 Farm Bill hemp definition, the FDA position that these compounds are not lawful dietary supplements, and a wave of state restrictions. Some states have banned or capped hemp-derived THC while others regulate it. If a rescheduling action covers marijuana, it may not resolve the hemp-derived question at all. Read the scope section of any rule before assuming it covers every THC product on a shelf.
How to verify the current status yourself
- Check the Federal Register for the proposed rule and any final rule, and note the effective date.
- Check DEA diversion control materials for the schedule list and handler guidance.
- Check your state cannabis regulator's bulletins, because state law can be stricter than federal law.
- Treat headlines claiming THC is legal now as unverified until a dated final rule exists.
Bottom line for shoppers, patients, and operators
Buy and carry cannabis the way your state allows, because that is the rule that governs the counter. If you are a patient, confirm your state medical program paperwork with your dispensary team. If you are an operator, talk to a tax professional about what Schedule III would do to your deductions before assuming relief. Follow the final rule, not the headline.
