Is CBD Legal in the United States? What the 2018 Farm Bill Really Says

Short answer: hemp-derived CBD containing no more than 0.3% delta-9 THC is legal at the federal level in the United States, thanks to the 2018 Farm Bill. The longer answer involves an important distinction between hemp and marijuana, plus a patchwork of state rules worth understanding before you buy.

Key Takeaways

• The 2018 Farm Bill removed hemp (cannabis with no more than 0.3% delta-9 THC) from the federal Controlled Substances Act.
• CBD derived from hemp is federally legal; CBD derived from marijuana remains federally controlled.
• States may impose their own restrictions, so local rules can differ in the details.
• Buying lab-tested products with published COAs is the best way to ensure what you buy is genuinely compliant hemp.

Hemp vs Marijuana: The Legal Line

Botanically, hemp and marijuana are the same species, Cannabis sativa. Legally, everything turns on delta-9 THC content. Cannabis testing at or below 0.3% delta-9 THC by dry weight is hemp; above that threshold it is marijuana under federal law. That is why the certificate of analysis matters so much: it is the documentary proof that a product sits on the legal side of the line. We explain how to check that number in our guide to reading lab reports.

What the 2018 Farm Bill Changed

The Agriculture Improvement Act of 2018 legalized hemp cultivation nationwide, made hemp farmers eligible for crop insurance, and removed hemp and its derivatives, including CBD, from the Controlled Substances Act. This opened the door to the modern American CBD marketplace, from tinctures and gummies to skincare and pet products.

Where the FDA Fits In

Legal to sell does not mean unregulated. The FDA prohibits marketing CBD products with claims that they treat or cure diseases, and it has not approved CBD as a food additive or dietary supplement ingredient. Responsible brands therefore market CBD as a wellness product, avoid medical claims, and back their labels with independent testing.

Do States Have Their Own Rules?

Yes. Most states permit hemp-derived CBD in line with federal law, but some regulate specific product types, add labeling requirements, or restrict certain cannabinoids. Rules also change as legislatures update them. If you are unsure, check your state’s department of agriculture or health website for current guidance; it is the authoritative source for local requirements.

Can You Travel with CBD?

TSA permits hemp-derived CBD products that comply with the Farm Bill in carry-on and checked bags. Keep products in original labeled packaging, and consider carrying a copy of the COA when flying. International travel is another matter entirely: many countries prohibit CBD, so never assume US rules apply abroad.

How to Buy Legal, Compliant CBD

Choose products made from US-grown hemp, manufactured in GMP-certified facilities, with batch-specific third-party lab results that confirm THC compliance. Every product in the First Class Organics shop meets that standard, with COAs published on our Lab Tests page.
