FDA's position on CBD has not changed since 2024. The federal definition of hemp changes in November 2026. Here is what each says, from the source.
7 U.S.C. 1639o and the 2025 amendment, read Oct 2, 2026. See source

FDA has approved one drug containing CBD, a prescription medicine, and states that there are no other approved drug products containing CBD1.
CBD cannot be sold as a dietary supplement: FDA has concluded that THC and CBD products are excluded from the dietary supplement definition1.
For products applied to the skin, FDA explains that cosmetics and their ingredients do not need premarket approval, except most color additives. But a topical product marketed with claims about the body's structure or function, or about disease, is regulated as a drug1. That is why this site describes topicals only by their contents and never by what they might do.
| Rule | Until the amendment takes effect | From November 12, 2026 |
|---|---|---|
| What is measured2 | Delta-9 THC | Total THC, including THCA |
| Plant and extract limit2 | Not more than 0.3 percent, dry weight | Not more than 0.3 percent total THC, dry weight |
| Finished consumer products2 | No separate per-container limit | Excluded from hemp if more than 0.4 milligrams combined THC (and similar cannabinoids) per container |
| Topicals2 | Covered by the general definition | Expressly included: hemp-derived cannabinoid products include topical application |

The amendment takes effect 365 days after November 12, 2025. HHS is to list cannabinoids with THC-like effects.
The 0.4 milligram limit is per container, not per gram. Medterra, for example, says its full spectrum products contain 2mg to 5mg of THC each, while its isolate and broad spectrum products are THC-free3. Under the amended definition, a finished product with more than 0.4mg of THC per container is no longer hemp2; how retailers respond is up to them.
This is why CalmLeaf Guide lists only products the merchant describes as THC-free. A product described as THC-free still has a lab report: check the total THC result on the certificate for your batch. See reading a CBD lab report.
State laws on CBD differ and are changing alongside the federal rule. This guide covers federal law only and is not legal advice.

We do not earn anything from purchases today. Every product link is a plain link to the merchant's own page, without an affiliate code. We may join merchants' affiliate programs in the future, and this notice will say so before that changes.
Prices, sizes, shipping and lab reports belong to each merchant and can change. The merchant's own page is the final word on price, availability and terms.
CalmLeaf Guide covers topical, THC-free CBD only and makes no health claims. Nothing here is medical or legal advice. Ask a doctor or pharmacist before using CBD with other medicines.
