When it comes to traveling with cannabis chapstick, the rules may not be as simple as tossing it into a carry-on. Whether or not a traveler can bring it along depends primarily on what type of cannabis extract is used in the product. Hemp-derived chapsticks containing 0.3% or less delta-9 THC by dry weight are federally legal in the United States, while marijuana-derived products—those with THC levels above that threshold—remain illegal under federal law.
For domestic air travel, the Transportation Security Administration (TSA) follows federal guidelines. This means hemp-based chapsticks and CBD balms that meet federal standards can generally fly without issue. TSA officers are focused on security, not searching for cannabis products, but if an item appears to violate the law, they must refer it to local authorities. To avoid confusion, travelers are encouraged to keep products clearly labeled and, when possible, carry a Certificate of Analysis (COA) verifying that the THC content is compliant.
Fortunately, most chapsticks are considered solid cosmetics rather than liquids, which means they do not fall under the 3-1-1 liquids rule. However, balms or ointments that have a semi-liquid consistency could be treated as liquids and should follow the standard 3.4-ounce limit for carry-on bags.
The rules change dramatically once borders come into play. Crossing any international boundary with cannabis—even legal, hemp-derived CBD—can result in seizure or legal penalties. Many countries, including Canada, prohibit bringing any form of cannabis across their borders. Similarly, U.S. Customs and Border Protection enforces federal law, which classifies cannabis as illegal regardless of local state laws. Travelers are strongly advised to buy cannabis-based personal care products at their destination rather than risk transporting them.
Even within the U.S., federal jurisdiction can complicate matters. Carrying marijuana-derived chapsticks across state lines technically violates federal law, even between states where cannabis is legal. Airlines also follow federal policy, so any product exceeding 0.3% THC is not permitted on board. Additionally, cannabis remains prohibited on all federal lands—such as national parks, forests, and monuments—meaning even a small cannabis-infused lip balm could be considered illegal there.
The takeaway: hemp-derived cannabis chapsticks with less than 0.3% THC are generally permitted for domestic flights and everyday travel within the U.S., as long as they are properly labeled and legally produced. Marijuana-derived versions, on the other hand, should be left at home. Travelers can stay compliant by verifying product contents, respecting liquid limits for semi-liquid items, avoiding use on federal land, and never carrying cannabis products across international borders.
