Key Takeaways

  • Flying with THC-O may be legal, but you need to check local laws in your target destination.
  • Also plan to pack THC-O according to THC-O guidelines for liquids, vape batteries, or other rules that may apply.
  • As always, make sure you buy only high-quality THC-O from a trustworthy source. Flying with products that contain more than the legal amount of Delta-9 may be cause for serious trouble.

Is it Legal to Fly with THC-O?

Before packing up for a flight, it's always a good idea to check with your chosen airline to see what you can and can't pack. This is true even for items that aren't THC products. Remember that you'll likely have to forfeit anything you accidentally pack that's unapproved (and nobody wants to have to throw away that whole bottle of expensive face cream because it's just over the limit for liquids on the flight). You may be surprised what you can and can’t legally carry on a plane (like batteries).

Where you are travelling is also important, so be sure to look into the local regulations of your target destination.

Now, let's dig into the most important questions–Can you fly with THC-O nationally? What about internationally?

Here’s what we know:

Local Flights with THC-O


THC-O is federally legal, but that doesn’t necessarily clarify the rules on flying with THC-O. The TSA doesn’t address THC-O specifically, but does clarify that they aren’t exactly looking for it:

“TSA’s screening procedures are focused on security and are designed to detect potential threats to aviation and passengers. Accordingly, TSA security officers do not search for marijuana or other illegal drugs…”

In other words, the TSA isn’t looking for your THC-O products or any other hemp products you may stash away in your luggage, but does that mean it’s safe to carry them with you?

Maybe so, depending on how you interpret the TSA’s cannabis regulations.

TSA Rules for Cannabis Products

The TSA updated their rules in 2019 in response to the 2018 Farm Bill’s legalization of hemp and hemp products.

The previous rules banned all “marijuana and cannabis-infused products,” but the new rule makes an exception for “products that contain no more than 0.3 percent THC on a dry weight basis or are approved by the FDA,” referencing the Agricultural Improvement Act of 2018 for clarification.

Here, federal law specifies that hemp products, including cannabinoids, isomers, and other extracts that contain less than 0.3% Delta-9-THC, are federally legal. The new laws also removed tetrahydrocannabinols in hemp from the Controlled Substances Act.

That means that THC-O is not a Controlled Substance and is instead a legal hemp product, and there’s nothing specifically barring you from carrying THC-O on the plane. In fact, TSA is not exactly concerned with sniffing out cannabis products. If they do happen to find illicit substances while searching your bags, however, their policy is to turn it over to local law enforcement.

Of course, even if your THC-O products are flagged as Delta-9-THC products by mistake, you’re going to be subject to interrogation while the products are being tested.

It may be handy to carry documentation of your purchase (and any relevant test results) that prove that your THC-O is, in fact, a legal hemp product. Worst case scenario, your hemp products may be confiscated, but you’re unlikely to be arrested or prosecuted.

This is one reason that it's incredibly important to only buy THC-O from a reputable, trustworthy source. If you happen to be carrying THC-O products that have more than the legally allowed amount of Delta-9, you may find yourself in a much stickier situation.

Check THC-O State Laws Before You Fly

We mentioned earlier that checking local legislation at your final destination is important. Just because carrying THC-O is unlikely to cause you any issues with TSA doesn’t mean you won’t have issued with local law enforcement if you’re caught with your products after you arrive.

To see if THC-O is legal in your destination state, read “Where is THC-O Legal?”

Flying Internationally with THC-O

Even if you’ve never taken an international flight, you probably realize that U.S. laws don’t matter once you leave the country. Unfortunately, the U.S. is one of the first areas to legalize hemp and hemp products, so you may have a harder time taking THC-O on international flights than on local ones.

The majority of countries around the globe (including the U.S.) consider cannabis to be an illicit substance, and some countries have incredibly harsh penalties for cannabis possession. Unlike the U.S, unfortunately, many areas do not separate hemp and cannabis products.

That means that cannabis and hemp products, including oils, vapes, and other concentrate products may be subject to harsh restrictions and penalties in place. Even in some areas where cannabis is legal, there may still be penalties for products purchased outside of the local area or for possession of paraphernalia.

If you’re flying with medical cannabis products, it may be worth researching the laws in your destination area. In most cases, carrying any sort of cannabis product on an international flight is risky to say the least and is likely to end in a run-in with customs or local law enforcement. If you’re flying to a country that has legalized cannabis, it may be a better idea to just purchase your products after you arrive.

The penalty for the possession of cannabis is harsh in some areas and may even result in imprisonment. In almost all cases, travelling internationally with THC-O is not worth the risk.

Storing THC-O for Your Flight

If you decide to fly with your THC-O products, whether in your carry-on or in your checked luggage, you need to make sure you store them in a manner that protects the product and meets TSA guidelines.

Here are some storage recommendations for popular Delta-8 products:

  • Solid products, like gummies, can be packed in carry-on or checked luggage. You can usually just leave these in there original packaging.
  • Liquid products, like oil or distillate, are subject to the rules for liquids when carried in a carry-on bag. According to the TSA, you’re allowed to carry one quart-sized bag filled with containers that hold 3.5 oz (100 mL) of liquid or less.
  • Vapes are one of the trickiest types of THC-O products to carry. Many airlines state that “Battery-powered electronic smoking devices, such as ‘e-cigarettes, e-cigs, e-cigars, e-pipes, e-hookahs, personal vaporizers, electronic nicotine delivery systems,’ can be brought as carry-on items only.” The liquid portion of the vape is subject to the rules for liquids.

Tips for Flying with THC-O Products

After you’ve checked with your airline and verified local regulations, here are some tips for flying with THC-O that can help make the process go smoothly:

  • Leave products in their original, sealed packaging when possible.
  • Carry documentation and necessary test results to prove that the product is a legal hemp product.
  • Seal any open oils or vape liquids with tape to prevent leaking. Place extra oils inside a plastic, leak-proof bag before stashing them in your checked bags to protect your other luggage from getting ruined.
  • Make sure that the THC-O products you buy are made according to federal standards for legal hemp products. Look for the test results to prove it. (Vida Optima products are always 100% Farm Bill compliant. Shop our Elev8 Collection to view our third-party lab reports.)
