Is CBD legal?
TL;DR — What the Evidence Shows
CBD from hemp is legal under federal law right now. This changes on November 12, 2026. New rules will make many products that are currently legal illegal.
What is the current legal status?
The 2018 Farm Bill legalized hemp-derived CBD at the federal level. Under this law, hemp products are legal if they contain less than 0.3% delta-9 THC by dry weight.
"Legal" does not mean "FDA-approved" or "quality-controlled." The FDA has not approved any over-the-counter CBD product as a drug or dietary supplement. CBD products are sold without FDA evaluation for safety, effectiveness, or quality.
November 12, 2026
Federal rules are changing
Section 781 of the Continuing Appropriations Act (Section 781 2025) switches from a delta-9-only THC standard to a "total THC" standard. Finished products will be capped at 0.4 mg total THC per container. Many current full-spectrum products will exceed this limit and become illegal to sell.
What changes on November 12, 2026?
Old rule (current)
Only delta-9 THC is counted. Measured at 0.3% of dry weight. Other forms of THC (THCA, delta-8) are not included in the calculation.
New rule (effective November 12, 2026)
Total THC is counted. This includes delta-9 THC, THCA (which converts to THC when heated), delta-8 THC, and other THC-class cannabinoids. Finished products for human use are capped at 0.4 mg total THC per container.
The 0.4 mg cap is extremely low. Many current CBD oils contain 1 to 5 mg of THC per bottle. A single full-spectrum CBD tincture can contain 10 times the new limit. (Arnold & Porter 2025)
| Product type | Typical THC | Current federal status | After November 12, 2026 |
|---|---|---|---|
| CBD Isolate (zero THC) | 0 mg | Legal | Likely legal — no THC, meets all thresholds |
| Broad-Spectrum CBD (THC removed) | ~0 mg | Legal | Likely legal — if truly zero THC |
| Full-Spectrum CBD Oil (30 mL bottle) | 1–5 mg per bottle | Legal (under 0.3% delta-9 THC) | Likely illegal — exceeds the 0.4 mg per-container cap |
| Full-Spectrum CBD Tincture (60 mL bottle) | 2–6 mg per bottle | Legal (under 0.3% delta-9 THC) | Likely illegal — exceeds the 0.4 mg per-container cap |
What does this mean for each product type?
- CBD Isolate (zero THC) — should remain legal. No THC to measure.
- Broad-Spectrum (THC removed) — likely legal if THC is truly removed, not merely reduced. Testing accuracy matters.
- Full-Spectrum (contains THC) — most current products will not comply. Significant reformulation would be needed, or products become federally unlawful.
Do state laws also apply?
Yes. State laws add an additional layer of variation on top of federal law.
- About 24 states plus DC permit retail sale of hemp-derived CBD with minimal restrictions.
- About 20 states impose additional conditions (licensing, registration, formulation limits).
- A handful of states — Idaho, for example — permit only completely THC-free hemp extracts.
State laws vary and change frequently.
Legal information on this page reflects federal law as of March 2026. State laws vary and may change. Whether Congress will modify Section 781 before November 2026 remains uncertain. Multiple bills have been introduced but none has advanced through committee. This page is not legal advice.
Legal status does not indicate safety
CBD affects enzymes that process about 60 out of 100 prescription drugs. See the drug interaction page for documented interactions.
