You're packing for a trip, and your eye catches the Floral seltzers in the fridge. Can you bring them? Should you bring them? What happens if TSA finds them in your bag? Traveling with THC drinks is one of the most common questions in the cannabis beverage space — and the answer is frustratingly nuanced. It depends on the type of THC (hemp-derived vs. marijuana-derived), your departure and arrival states, TSA's current enforcement posture, and whether you're willing to accept any level of risk. This guide gives you the full picture: what the law actually says, what TSA actually does, and what practical options exist for having THC beverages wherever you're headed. We're not lawyers, and this isn't legal advice — but we'll lay out the facts clearly enough for you to make an informed decision.
The Short Answer (And Why It's Complicated)
Hemp-derived THC drinks — like Floral's seltzers — are federally legal under the 2018 Farm Bill as long as they contain less than 0.3% Delta-9 THC by dry weight. In theory, that means you can possess them anywhere federal law applies, including airports. In practice, flying with THC beverages gets complicated fast.
First, there's the TSA liquid rule. Carry-on bags are limited to containers of 3.4 ounces (100 mL) or less. A standard 12-ounce can of THC seltzer doesn't fit through that checkpoint — period. So your carry-on is out unless you're traveling with a smaller format product.
Second, there's the reality gap between legal status and airport experience. Even though your hemp-derived product is federally compliant, the TSA agent inspecting your bag may not know that. And if they flag your beverage, the next conversation is with local law enforcement — whose interpretation of the law may differ from yours.
The simplest, stress-free solution? Ship your THC drinks to your destination ahead of time and skip the airport hassle entirely. Floral ships to most states where hemp-derived THC beverages are legal.
TSA Rules on THC Products
Here's what TSA has actually said about this: their officers are focused on security threats to aircraft and passengers. They are not specifically searching for drugs, cannabis, or THC products. That's straight from TSA's own website.
However — and this is the part that matters — if a TSA officer discovers a substance they believe could be illegal during a routine screening, they will refer the matter to local law enforcement. They don't make the legal call themselves. The local police do.
TSA has updated its guidance to acknowledge that hemp products compliant with the 2018 Farm Bill are federally legal. But here's the practical problem: there's no quick way for an airport officer to test whether a canned beverage contains 0.28% THC (legal) or 0.35% THC (not legal) on the spot. They can't run a lab analysis at the checkpoint. So enforcement comes down to officer discretion, which is inherently inconsistent.
Some travelers report flying with hemp-derived products without any issue. Others report having products confiscated or being questioned. The experience varies by airport, by agent, and by day. That unpredictability is exactly why we recommend shipping instead of carrying.
Hemp-Derived vs. Marijuana-Derived: The Legal Distinction
The legal status of your THC drink hinges entirely on where the THC came from. Under the 2018 Farm Bill, hemp-derived products containing less than 0.3% Delta-9 THC by dry weight are federally legal. Marijuana-derived products remain a Schedule I controlled substance under federal law, regardless of what your state allows.
All of Floral's products are hemp-derived and compliant with the Farm Bill. The THC in our seltzers and cocktails is Delta-9 THC sourced from hemp — the same molecule found in marijuana, but from a legally distinct plant source.
The challenge is that there's no way to visually distinguish a hemp-derived THC beverage from a marijuana-derived one. They look identical. That's why carrying documentation matters if you choose to travel with them. Your best bet is to keep products in their original packaging (which should reference hemp derivation and Farm Bill compliance) and carry a copy of the Certificate of Analysis (COA) — the third-party lab report verifying the THC concentration.
Will documentation guarantee a smooth experience? No. But it's significantly better than having no proof at all if questions arise.
State-by-State Considerations
Federal legality is only half the equation. When you land, you're subject to the laws of your destination state. And not every state has embraced hemp-derived THC with open arms.
Before You Fly: Research Checklist
-
Departure state: Is hemp-derived THC legal and unrestricted where you're leaving from?
-
Destination state: Does your arrival state allow hemp-derived THC products? Some states (like Idaho and certain others) have restrictive policies on all THC products regardless of source.
-
Layover states: If your flight connects through a restrictive state, you're technically in possession in that jurisdiction during your layover.
-
Local regulations: Some cities and counties have their own rules on top of state law. A product legal in one city might not be legal 50 miles away in the same state.
The safest approach is simple: research both your departure and destination states before you travel. If either one has restrictive hemp policies, leave your THC drinks at home and order ahead to your destination instead.
Smart Alternatives for Traveling with THC
You don't have to choose between going without and risking airport complications. Here are practical options ranked from safest to riskiest.
Your Travel Options
Option 1: Ship to Your Destination (Recommended)
Order from Floral's website and have your seltzers shipped directly to your hotel, rental, or wherever you're staying. No TSA interaction, no legal gray areas, no confiscated cans. This is the cleanest solution by far.
Option 2: Purchase Locally at Your Destination
If your destination state has a healthy hemp-derived THC market, you may find beverages at local shops, dispensaries, or specialty retailers. Quality varies — look for brands with third-party lab testing and clear labeling.
Option 3: Checked Luggage (If You Must)
If you insist on bringing THC drinks with you, checked luggage is the only viable option for full-size cans (the TSA liquid limit rules out carry-on). Keep products in original packaging, carry your COA documentation, and understand that you're accepting the risk of questions at your destination.
A few additional tips if you choose to carry: never open cans before going through the airport — sealed, commercially packaged products are far less likely to draw scrutiny than opened containers. And always keep your lab results or COA accessible. If anyone asks, having documentation ready shows you've done your homework.
International Travel: Don't Even Think About It
If your trip crosses international borders, the calculus changes completely. Leave all THC products — hemp-derived or otherwise — at home.
International drug laws are strict, often punitive, and rarely make exceptions for hemp-derived products. Countries that have zero-tolerance drug policies can impose severe criminal penalties for possessing any amount of THC. This includes many popular tourist destinations in Asia, the Middle East, and parts of Europe.
Even countries with relatively progressive cannabis laws may not recognize the 2018 Farm Bill's hemp distinction. The legal framework that makes Floral's products compliant in most U.S. states has no bearing once you leave American jurisdiction.
The risk is simply not worth it. If you're traveling internationally, enjoy your THC beverages before you leave and after you return. No can of seltzer is worth a criminal charge in a foreign country.
The Bottom Line on THC and Air Travel
Traveling with THC drinks is legally and practically complicated. While hemp-derived products under 0.3% Delta-9 THC are federally legal under the 2018 Farm Bill, the intersection of TSA policies, airline rules, and varying state laws creates enough gray area that caution is the smartest approach.
The easiest solution? Order ahead. Have Floral shipped directly to your destination so your beverages are waiting when you arrive — no airport stress, no legal gray areas, no confiscated cans.
Skip the travel hassle — order Floral shipped directly to your destination. Our THC seltzers and cocktails ship to most states where hemp-derived THC beverages are legal. Travel light, arrive refreshed, and enjoy responsibly.
