Short answer: Yes, kind of — in most cases you can fly within the United States with hemp-derived THC drinks, as long as the product is compliant with federal hemp law (no more than 0.3% delta-9 THC on a dry weight basis) and you respect the TSA liquids rule by packing full-size cans and bottles in your checked bag. The TSA is not searching for your seltzer. But "can you" and "should you" aren't the same question, and the legal picture is changing in late 2026. Here's everything a 21+ traveler needs to know before tossing a can in the carry-on.
If you've ever stood in a security line wondering whether the four-pack in your duffel is going to set off an awkward conversation, you're not alone. Hemp-derived THC beverages have become one of the fastest-growing categories in the country, which means a lot of people are now asking a very practical question that didn't really exist five years ago: can you fly with THC drinks? Let's break it down the way we wish someone had broken it down for us — clearly, honestly, and without the legal hand-waving.
Hemp-derived vs. marijuana-derived: the distinction that decides everything
Before we talk about airports, we have to talk about chemistry and law, because the entire answer hinges on one difference.
Under the 2018 Farm Bill, "hemp" is defined as cannabis containing no more than 0.3% delta-9 THC on a dry weight basis. Hemp and its derivatives were removed from the Controlled Substances Act, which is why hemp-derived THC beverages can be sold over the counter in many states. A 10mg can of hemp-derived seltzer clears that threshold because the limit is calculated by the dry weight of the source plant — not by milligrams of THC in the finished can.
Marijuana-derived products are a completely different legal animal. Anything above that 0.3% line is still federally classified as marijuana, regardless of whether your home state has legalized adult use. A dispensary gummy from a recreational-legal state is still a federally controlled substance the moment you step into an airport security line.
This matters because airports and airspace fall under federal jurisdiction. So the relevant question at the checkpoint isn't "is this legal in my state?" — it's "is this a federally legal hemp product?" If you'd like a deeper dive on how cannabinoids behave and where the science sits, our research and science hub is a good next stop.
What the TSA actually does (and doesn't do) about THC drinks
Here's the part that surprises most people: the TSA is not looking for your THC drinks.
According to the TSA's official medical marijuana and CBD guidance, the agency's screening officers are focused on threats to aviation security — not on enforcing drug laws or hunting through your snacks. The TSA has stated plainly that its officers do not search for illegal substances. Their X-ray machines are calibrated for weapons and explosives, not for measuring cannabinoid content, and they have no spot-test for THC percentage.
That said, there's an important caveat the TSA is equally clear about: if an officer happens to discover something that appears to be illegal during routine screening, they're required to refer it to local law enforcement. The TSA doesn't make the legal call itself — it hands the situation off. What happens next depends entirely on the laws of the state and the airport where you're standing.
For a Farm Bill–compliant hemp beverage in its original, clearly labeled packaging, this is almost never an issue. Sealed, branded, store-bought cans look like exactly what they are. The friction tends to come from ambiguous products — unlabeled bottles, homemade infusions, vape cartridges, or anything an officer can't immediately identify. The lesson: keep it sealed, keep it labeled, keep it boring.
The liquids problem: why your THC seltzer probably belongs in checked baggage
This is the single most practical thing to know, and it has nothing to do with THC at all.
Hemp-derived THC drinks are liquids, and liquids in your carry-on are governed by the TSA's familiar 3-1-1 rule: every container must be 3.4 ounces (100 milliliters) or less and fit inside a single quart-sized bag. (You can review the full breakdown on the TSA "What Can I Bring?" list.)
A standard THC seltzer can is 8 to 12 ounces. A bottle of infused bubbly is 750 milliliters. Both blow right past the 3.4-ounce carry-on limit — which means a full-size can or bottle is not making it through the checkpoint in your carry-on, THC or no THC. Bottled water gets dumped for the same reason.
So where do they go? Your checked bag. There is no liquid-volume limit for beverages in checked luggage, and sealed cans and bottles travel just fine down in the hold. Pack them upright, ideally in a sealable bag or wrapped in clothing in case of pressure changes, and you're set.
If you genuinely need a THC drink in your carry-on, the only compliant option is a travel-size format under 3.4 ounces — think shots or concentrated single-serve tonics rather than a full seltzer. Otherwise, check the four-pack and grab a sparkling water for the flight.
Labels, COAs, and packing smart
You don't legally need paperwork to fly with a compliant hemp beverage, but a little preparation removes nearly all the friction.
Keep products in their original, sealed packaging. A branded can with the cannabinoid content, "hemp-derived" language, and a 21+ designation printed right on it answers most questions before they're asked.
Carry the Certificate of Analysis (COA). A COA is the third-party lab report showing the product's cannabinoid profile and confirming delta-9 THC at or below 0.3% by dry weight. Reputable brands make these easy to find — usually via a QR code on the can or a lookup tool on their website. Save a screenshot or keep the link handy on your phone. If a question ever does come up, a batch-matched COA is the cleanest way to show your product is a federally legal hemp product.
Skip the gray-area formats. Loose, unlabeled, or homemade products invite scrutiny. So does anything that visually resembles marijuana flower. The goal is to look exactly like the over-the-counter consumer product you're carrying — because that's what it is.

State lines and airport jurisdiction: legal where you take off ≠ legal where you land
Here's where "can you fly with THC drinks" gets genuinely complicated, and where a lot of confident internet answers get it wrong.
A flight touches at least three legal environments: your departure airport's state, the federal airspace in between, and your destination airport's state. Hemp-derived THC is federally legal under the current Farm Bill standard, so the federal leg is generally fine. But individual states regulate hemp-derived cannabinoids very differently — and a growing number have restricted, taxed, or outright banned certain hemp THC products.
Because any law-enforcement referral at a checkpoint is handled under local law, your exposure is shaped by the state you're physically standing in. A product that's freely sold in your home state may be restricted at your destination. This is not a reason to panic, but it is a reason to do five minutes of homework before you fly: check the hemp rules in both the state you're leaving and the state you're arriving in.
A quick word for Minnesota travelers
If you're flying out of MSP, Minnesota's hemp-derived THC framework is one of the more clearly defined in the country, capping lower-potency edible and beverage products at 10mg of THC per serving. That clarity is part of why a strong, compliant beverage scene has grown here.
One non-negotiable reminder, though: once you land and you're back behind the wheel, Minnesota treats driving while impaired by THC exactly like alcohol — a BWI is a DWI. Flying with your drinks is a packing question. Driving after consuming them is a safety and legal question, and the answer there is always: don't.
International travel: just don't
We'll keep this one short because the rule is simple. Do not fly internationally with any THC product — hemp-derived or otherwise.
The moment you cross a border, you're no longer dealing with the TSA. You're dealing with U.S. Customs and Border Protection on the way back and foreign customs authorities on the way out — and both enforce controlled-substance laws at a "bright line" standard. CBP has historically treated cannabis products, including hemp, as substances of interest at ports of entry, and a "hemp-derived" label is not a magic shield abroad. Many countries impose severe penalties for any cannabis-related product, full stop.
If you want a THC beverage at your international destination and it's legal there, buy it when you arrive. Don't pack it. The downside risk is wildly out of proportion to the convenience.
The November 12, 2026 change every hemp drinker should know about
This is the most important date in this entire article, and it's why we keep saying "as of right now."
A federal provision known as Section 781, part of the appropriations package signed in November 2025, is scheduled to take effect on November 12, 2026. When it does, it will redefine "hemp" in two major ways: it replaces the delta-9-only standard with a "total THC" standard (counting THCA and other THC isomers), and it caps finished consumable products at 0.4mg of total THC per container. You can read the legal breakdown in this Arnold & Porter advisory and the nonpartisan Congressional Research Service summary.
In plain English: the 0.4mg-per-container cap is far below the dose in essentially every hemp-derived THC beverage on shelves today. Unless Congress intervenes, the products this article is about would lose their federal hemp status — and with it, the TSA "yes" — after that date.
The story isn't over, though. There are active bipartisan efforts to delay or repeal the provision, including legislation co-sponsored by Minnesota's own Senator Amy Klobuchar alongside Senators Rand Paul and Jeff Merkley to push the timeline back, plus separate proposals to replace the ban with a sensible federal regulatory framework. We've been deeply involved in this fight. If you care about keeping safe, tested, lower-dose hemp beverages legal and available, learn the details and make your voice heard through our Section 781 advocacy hub.
Bottom line on timing: through November 11, 2026, the guidance in this article holds. After that date, the rules may tighten significantly — so always confirm the current federal status before you fly.
Your pre-flight THC drink checklist
Before you head to the airport, run through this:
- Confirm it's hemp-derived and compliant with the current 0.3% delta-9 federal standard.
- Pack full-size cans and bottles in your checked bag — they exceed the 3.4 oz carry-on liquid limit.
- Keep everything sealed and in original, labeled packaging.
- Save the COA to your phone, matched to the batch on the label.
- Check the hemp laws in both your departure and destination states.
- Never fly internationally with THC products of any kind.
- Re-check federal rules if you're traveling on or after November 12, 2026.
- Plan your ground transportation so you're never driving after consuming.
Why people are packing hemp beverages in the first place
The reason this question keeps coming up is that hemp-derived THC drinks have quietly become a travel staple for a specific kind of traveler: the sober-curious or "damp" lifestyle crowd who wants the social ritual of a drink in hand without the alcohol. A lower-dose seltzer fits neatly into a vacation, a destination wedding, a lake weekend, or an evening on a hotel balcony — and it travels lighter than a bottle of wine.
At 23rd State, we build our beverages for exactly those moments. Our FRESH PRESS sparkling perry and Blush Crush infused bubbly are crafted as approachable, 21+, hemp-derived alternatives to alcohol — the kind of thing you reach for when you want to unwind without waking up worse for it. (When you do travel with them, remember: checked bag, sealed cans, COA on your phone.) And because we think people deserve real information rather than marketing fluff, our beverages are anchored in observational research like the MoreBetter Real-World Infused Beverage Study, with individual results always varying from person to person.
Whether you're flying to a wedding, a reunion, or just a long weekend somewhere warm, knowing the rules means you can pack with confidence instead of crossing your fingers at the checkpoint.
Frequently asked questions
Can you bring THC drinks on a plane in your carry-on? Only if the container is 3.4 ounces (100 ml) or less, because of the TSA liquids rule. Standard 8–12 oz cans and 750 ml bottles must go in your checked bag, where there's no liquid-volume limit.
Will the TSA confiscate my hemp-derived THC seltzer? The TSA isn't searching for it, and Farm Bill–compliant hemp beverages in sealed, labeled packaging rarely cause issues. The main reason a can would be pulled from a carry-on is the liquids rule, not its contents — so pack full-size cans in your checked bag.
Do I need a COA to fly with THC drinks? Not legally, but it's smart. A Certificate of Analysis showing delta-9 THC at or below 0.3% by dry weight is the cleanest way to confirm your product is federally legal hemp if a question ever comes up. Keep a copy on your phone.
Is it legal to fly with THC drinks between two legal states? Federally, hemp-derived products under 0.3% delta-9 THC are currently legal, so the federal leg of your flight is generally fine. But state hemp laws vary, and any checkpoint referral is handled under local law — so check the rules in both your departure and destination states.
Can I fly internationally with hemp THC drinks? No. Customs and Border Protection and foreign customs authorities enforce controlled-substance laws strictly, and a "hemp-derived" label offers no protection abroad. Buy legal products at your destination instead — never pack them across a border.
Will I still be able to fly with THC drinks in 2027? That depends on Section 781, which is set to take effect November 12, 2026, and would redefine hemp in a way that affects most THC beverages. Bipartisan efforts to delay or replace it are ongoing. Always confirm the current federal status before traveling on or after that date.
Do THC drinks show up on a drug test? That's a separate and important question, especially if your job involves testing. We cover it in detail in our guide on whether THC drinks show up on a drug test.
This article is for general informational purposes only and is not legal advice. Cannabis and hemp laws vary by state and change frequently. 23rd State products are hemp-derived and intended for adults 21 and older. Always verify current TSA guidance, federal law, and the laws of your departure and destination states before traveling, and never consume and drive. Individual results vary.
