Is CBD legal in the USA?
David ReichUpdated:Key points at a glance:
CBD derived from hemp with no more than 0.3 percent Delta-9 THC is not classified as a controlled substance at federal level in the USA. However, the FDA does not generally permit CBD in food or dietary supplements. Individual states set their own rules regarding age limits, labelling and permissible levels. On flights within the USA, CBD products containing up to 0.3 percent THC are usually permitted, with liquids limited to 100 millilitres. Security staff decide on a case-by-case basis. Bringing CBD products across borders can be risky. It is advisable to carry a certificate of analysis (COA) and to avoid Delta-8 products.
Which products contain CBD but no THC?
First, a brief overview of which products usually contain CBD but are free from THC. THC is more sensitive from a legal perspective in many countries. Here are some of the most common categories:
- CBD oils and tinctures: These liquids are typically placed under the tongue.
- CBD capsules and tablets: A convenient way to take CBD, similar to food supplements.
- CBD edibles: This includes gummies, chocolate, drinks and other foods that contain CBD.
- CBD vape products: These products are used for inhaling vapour. They include e‑liquids and vape pens.
- CBD skincare products: Creams, ointments, lotions and balms that are applied to the skin.
Is CBD legal to bring into the USA and can you fly with it?
Airport security (TSA): CBD products are generally allowed in both hand luggage and checked baggage if they:
- contain no more than 0.3% Δ9‑THC (by dry weight), or
- are approved by the FDA (for example, the prescription medicine Epidiolex).
You must also comply with the 3‑1‑1 liquids rule for anything liquid in hand luggage. The final decision always rests with the TSA officer at the checkpoint. (tsa.gov)
Border control (CBP) on international arrival: US ports of entry are federal customs posts. Products that are treated as “marijuana/THC” can be seized. Violations can lead to fines and, for Global Entry members, removal from the programme.
For CBD foods and supplements, the FDA can refuse entry on food law grounds (including 21 U.S.C. § 331(ll)). To reduce risk:
- carry only personal amounts
- keep products in their original packaging
- avoid products marketed with THC‑style wording such as “Delta‑8/THC gummies”.
| Scenario | Permitted? | What to watch out for |
|---|---|---|
| CBD oil in hand luggage | Yes, if ≤0,3% Δ9‑THC; amount per container ≤100 ml (3‑1‑1 rule) | Carry a certificate of analysis (COA); keep the bottle sealed; ensure clear labelling. (tsa.gov) |
| CBD capsules/gummies from abroad | Risky; the FDA may prohibit import on food law grounds | Preferably buy in the USA; otherwise carry a COA, only personal amounts, and avoid labels with explicit health claims. (fda.gov) |
| Epidiolex with prescription | Permitted (FDA‑approved medicine) | Carry it in its original packaging together with the prescription. (fda.gov) |
| “Delta‑8/THC‑O” and similar “intoxicating hemp” | Very risky | The DEA regards synthetically produced THC derivatives as controlled; they may be seized at borders. (govinfo.gov) |
Tip: Carry a printed certificate of analysis (COA) with batch number, Δ9‑THC content and QR code/URL. Some states even require a QR code or link to the COA on the retail label. (dshs.texas.gov)
For international travel to the USA, CBD at or below the 0.3% Δ9‑THC limit may still be stopped at the border, especially if it is a food or supplement, and decisions are made case by case by CBP and the FDA.
CBD legality in the USA: purchase, possession and use
At federal level, CBD from lawfully produced hemp (≤0.3% Δ9‑THC by dry weight) is not a controlled substance.
However:
- the marketing of CBD in foods and food supplements remains under FDA control
- the FDA has not granted broad authorisation for CBD in foods or dietary supplements
- individual states add their own rules on:
- labelling and testing
- age limits
- permitted product types (for example “smokable hemp”)
- maximum THC amounts and bans on certain cannabinoids.
In everyday practice, when buying CBD in the USA it is advisable to choose products that have:
- a clear batch or lot number
- a QR code or web link to the COA
- a transparent declaration of Δ9‑THC content.
Avoid products advertised as intoxicating, such as “intoxicating hemp” or “high potency”, especially if they reference “Delta‑8/‑10”, “THC‑O” or “HHC”. (govinfo.gov)
CBD law in US states: key regional differences
The answer to “Is CBD legal in the USA?” also depends on which state you are in. The examples below show how state‑level CBD rules can differ, including age limits, CBD THC limits, labelling, and whether CBD is treated as a food.
Always check the official website of the state you plan to visit. (ams.usda.gov)
| State | Key points (selection) | Official body/source |
|---|---|---|
| California | Hemp‑derived foods/dietary products are regulated; since 09/2024, “detectable” THC per serving in hemp foods is prohibited; sales typically restricted to those aged 21+. (cdph.ca.gov) | CDPH notice (Emergency Regs) (cdph.ca.gov) |
| New York | Dedicated “Cannabinoid Hemp” programme (licensing for sale/processing; quality, labelling and testing requirements; consumer information). Sales are often limited to 21+. (cannabis.ny.gov) | OCM Cannabinoid Hemp (cannabis.ny.gov) |
| Texas | “Consumable hemp products” are permitted; strict labelling including URL/QR code to the COA and confirmation of ≤0.3% Δ9‑THC. (dshs.texas.gov) | Texas DSHS – labelling (dshs.texas.gov) |
| Virginia | For retail sale: ≤0.3% “total THC”; maximum 2 mg total THC per package, unless the CBD:THC ratio is ≥25:1; 21+ notice, COA required. (vdacs.virginia.gov, law.lis.virginia.gov) | VDACS – Hemp Product Enforcement (vdacs.virginia.gov) |
| Idaho | Very strict: retail CBD must contain 0.0% THC; hemp foods are heavily restricted (essentially only hemp seed ingredients). (agri.idaho.gov) | ISDA – Hemp FAQ (agri.idaho.gov) |
| Colorado | Hemp in food is generally permitted; “safe harbour” rules, THC limits and proof of origin are required (6 CCR 1010‑24, effective 14.01.2024). (cdphe.colorado.gov) | CDPHE – Hemp in Food (cdphe.colorado.gov) |
Note: States may not prohibit the transport of lawfully produced hemp products through their territory (Farm Bill Sec. 10114), but they can adopt stricter rules for sale and for products on their markets. When planning travel across state lines, check the regulations in place at your destination in advance. (law.cornell.edu)
Within the USA, federally legal hemp CBD can still face very different rules from state to state, so you need to check the CBD law and THC limits in the specific state you are visiting or buying products in.
CBD travel rules in the USA: practical tips
-
COA documentation: Print and store the COA digitally. Check:
- product name
- batch/lot number
- laboratory accreditation (ISO/IEC 17025)
- Δ9‑THC value (≤0.3% by dry weight).
- Avoid “intoxicating hemp”: Do not travel with Delta‑8/‑10, THC‑O, HHC and similar products, especially at airports and when crossing borders. (govinfo.gov)
- Buy in the USA where possible: Purchase locally from reputable providers whose labels include a QR code or URL linking to the COA. (dshs.texas.gov)
- Flights: For hand luggage, liquid CBD products are limited to 100 ml per container; larger amounts should go in checked baggage. The TSA officer makes the final decision. (tsa.gov)
- Personal use quantities: Carry only personal amounts and avoid bulk or wholesale‑sized packs. For prescription CBD medicines such as Epidiolex, take the original packaging and a prescription. (fda.gov)
- Driving: Never drive if you may be impaired. CBD itself is generally not regarded as intoxicating, but mislabelled products can contain THC. In police checks, the detectable THC content is what matters. (fda.gov)
When travelling with CBD in the USA, keep to personal‑use amounts, stay under the 0.3% THC threshold, carry a matching COA, and be prepared for individual officers to make case‑by‑case decisions at security and borders.

FAQ: Is CBD legal in the USA for travellers?
Am I allowed to take CBD on a domestic flight within the USA?
Yes – provided the product contains ≤0.3% Δ9‑THC (dry weight) or is FDA‑approved. You must follow the 3‑1‑1 liquids rule, and the TSA officer at the checkpoint has the final say. (tsa.gov)
Can I bring CBD gummies from Europe?
This is sensitive. The FDA treats the placing on the market of CBD in foods and food supplements in interstate commerce as unauthorised, and imports can be refused. It is usually safer to buy CBD products in the USA and to carry a COA. (fda.gov)
Do the same CBD rules apply between US states?
No. The transport of lawfully produced hemp products may not be obstructed, but rules on sale and on products offered to consumers vary significantly, including age limits, THC thresholds and labelling requirements. (law.cornell.edu)
Checklist for CBD travel to and within the USA
