Is CBD Legal? US and Global Rules
Whether CBD is legal depends on more than a product’s THC percentage. The source plant, product type, intended use, health claims, seller, buyer’s age, and location can all affect its status. Rules for foods, supplements, cosmetics, medicines, vapes, and cannabis products may differ even within the same country.
This page is a regulatory starting point, not legal advice. Before buying, selling, importing, or traveling with CBD, confirm the current rules with the relevant national and local authorities.
United States
What the Federal Hemp Definition Does
The 2018 Farm Bill removed hemp from the federal Controlled Substances Act definition of marijuana. USDA defines hemp as Cannabis sativa L. and its derivatives containing no more than 0.3% delta-9 THC on a dry-weight basis.
That definition does not make every finished CBD product federally lawful. The Farm Bill preserved FDA authority over foods, drugs, dietary supplements, cosmetics, and other regulated products.
FDA Product Rules Still Apply
The FDA states that:
- CBD cannot currently be lawfully marketed as a dietary supplement under the federal framework it administers.
- Adding CBD to food sold in interstate commerce is prohibited under current federal law.
- Claims that a product treats disease can make it an unapproved drug.
- One purified prescription CBD medicine is FDA-approved for specific seizure conditions; retail CBD products are not approved substitutes.
State and local laws may be more restrictive or set separate rules for foods, inhalable products, age limits, registration, labeling, and sales. A product can meet the federal hemp definition and still violate another applicable rule.
European Union
CBD extracts and isolates intended for food are treated as novel foods under the EU framework because significant consumption before May 1997 has not been established. A novel-food determination does not authorize every product for sale.
Businesses and consumers should also check:
- Whether the specific novel food is authorized for its intended use
- National narcotics and THC rules
- Food-supplement, labeling, and health-claim requirements
- Whether the product is a food, cosmetic, vape, or medicine
- Import and customs requirements
EU member states may apply national controls, so a single Europe-wide THC percentage cannot determine legality.
United Kingdom
CBD extracts used in food are regulated as novel foods. The UK Food Standards Agency maintains a public list of applications allowed to continue through the assessment process. Inclusion on the list is not a general endorsement of safety or effectiveness.
The FSA also publishes precautionary advice for consumers of CBD foods. THC and other controlled cannabinoids are subject to separate drug rules, while flowers, vapes, cosmetics, and medicines are not governed solely by food law.
Check the current FSA CBD guidance and the product’s status rather than relying on “UK legal” marketing claims.
Canada
Canada regulates CBD under the Cannabis Act, whether it comes from industrial hemp or another cannabis variety. Health Canada states that CBD products are legal only when produced and sold in compliance with the Act and its regulations.
Key points include:
- Commercial production and processing require the appropriate federal licenses.
- Consumers generally buy through provincially or territorially authorized cannabis retailers or federally licensed medical sellers.
- Health claims require the applicable drug authorization.
- Importing or exporting CBD without the required permits is illegal.
Carrying cannabis products, including CBD, across the Canadian border without specific authorization is illegal—even when traveling between places where cannabis is otherwise legal.
Traveling With CBD
Permission to possess CBD at home does not mean it can cross a border or enter another state, province, or country.
Air travel in the United States
TSA states that certain cannabis-infused products remain illegal under federal law, except for products containing no more than 0.3% THC on a dry-weight basis or products that are FDA-approved. TSA screening focuses on security, but suspected violations may be referred to law enforcement. State law at both departure and arrival still matters.
International travel
Assume a retail CBD product may be restricted unless authorities in the destination and any transit countries confirm otherwise. A COA, original packaging, or prescription from another country does not override border law.
Do not carry CBD across the Canadian border without the required federal authorization. For other destinations, check with the embassy, customs authority, medicines regulator, and airline before traveling.
Product-Specific Questions to Check
Before buying or carrying CBD, confirm:
- How the jurisdiction defines hemp, cannabis, CBD, and THC
- Whether the rule measures delta-9 THC, total THC, or another standard
- Whether the finished product category is permitted
- Whether CBD may be added to food or sold as a supplement
- Whether inhalable products or flowers have separate restrictions
- Whether age, labeling, registration, or licensed-seller rules apply
- Whether import, export, mail, and travel are allowed
- Whether health claims make the product an unapproved medicine
The CBD product quality checklist can help assess labels, but quality documentation does not establish legal status.
