TSA Medical Marijuana Rules: What You Can and Cannot Fly With
TSA does not search for medical marijuana, but a state card does not make it legal at a federal checkpoint. Here is what happens when cannabis is found.
Short answer: TSA rules for CBD oil come down to one number — 0.3% THC. CBD products at or below that limit are permitted in both carry-on and checked bags, and they are screened like any other liquid. Because hemp-derived CBD is federally legal, agents are looking for security threats, not for your tincture. Here is how to pack it so screening stays quick and uneventful.

How much CBD oil can you bring on a plane?
Carry-on bottles must follow the 3-1-1 rule: containers of 3.4 oz (100 ml) or less, packed together in one clear quart-size bag per traveler. Anything larger — full-size tinctures, topicals, or bulk bottles — should go in checked luggage, where there is no liquid size limit.
Key Features
- CBD oil containing no more than 0.3% THC is allowed in carry-on and checked baggage
- Carry-on containers must be 3.4 oz (100 ml) or smaller and fit in a single quart-size clear bag
- Full-size bottles, creams, and capsules can travel in checked luggage
- Keep products in original, sealed packaging with the THC content printed on the label
- Products above 0.3% THC — including many full-spectrum oils and THC edibles — remain prohibited on flights
- Vape cartridges and batteries fall under separate e-cigarette rules and must stay in carry-on
- International itineraries may be subject to different laws at your destination
Does the TSA test for CBD or THC?
No. Screening is for security, not drug testing, and X-ray machines will not flag an oil. If a bag is hand-searched and a product looks inconsistent with federal limits, an agent may refer the matter to local law enforcement, which is why clear labeling matters.

Will CBD oil set off the scanner?
Liquids and oils do not trigger alarms on their own. A bottle may be pulled for routine liquid screening, so keep it accessible and outside your main packing cube.

Our oils are filled into UV-protective amber glass bottles with child-resistant dropper caps, batch-coded labels, and a printed cannabinoid panel showing delta-9 THC content. Formulas are CO2-extracted and third-party tested, so the paperwork matches what is on the bottle — useful if a screener asks.
Orders ship discreetly in plain, unbranded packaging within one business day, with tracking included. Unopened items can be returned within 30 days for a refund; if a bottle arrives damaged or leaking, contact support and we will replace it at no cost.
