Can You Take THCA Flower On A Plane?

Traveling with weed? Usually a hard no—unless you like unnecessary stress and side-eyes from TSA.

But here’s the thing about the cannabis industry—it’s nuanced af. Brands like Bloomz are legally selling high-THCA flower nationwide, and if you’ve ever smoked it, you know it hits just like dispensary-grade bud. So if it’s legal to buy, who’s to say you can’t fly with it—at least within the U.S.?

Well, that’s where things get complicated. Technically legal doesn’t always mean TSA-approved, and the last thing you want is to get held up at security over a poorly understood loophole.

Before you even think about packing that THCA stash, here’s everything you need to know—including the safest ways to travel with it, plus a few backup plans in case things don’t go your way.

First, let’s start with the basics. THCA is basically THC’s fraternal twin.

THC starts as its non-psychoactive acid precursor, THCA. In order for THCA to produce effects, it requires decarboxylation with heat (like the spark of a lighter).

Those effects? They’re the exact same as Delta-9 THC. However, since THCA is different from active Delta-9 THC, it falls under a legal loophole. The 2018 Farm Bill states that hemp products must contain 0.3% Delta-9 THC or less to be considered legal.

Since THCA isn’t technically Delta-9 THC, it’s legal to use and ship nationwide. Just be sure to check your local regulations, as laws differ from state to state and even county to county.

The short answer: traveling with THCA flower isn’t worth the risk.

Technically, under the 2018 Farm Bill, hemp-derived THCA flower is federally legal as long as it contains less than 0.3% Delta-9 THC by dry weight. That should mean you can travel with it, right? Not exactly.

TSA’s policies weren’t written with THCA in mind, and their officers aren’t trained to tell the difference between hemp and regular weed. If they find THCA flower in your bag, they don’t have the tools to test THC levels—so their default assumption? If it looks like weed, it’s weed.

And while THCA isn’t specifically mentioned in TSA’s rules, their site does state that cannabis and certain infused products—even some CBD oils—are illegal under federal law. That means if they suspect you’re carrying something illegal, they can and will involve local law enforcement.

Why It’s Not Worth The Stress

The problem isn’t just TSA—it’s how the law is enforced. Here’s where things get tricky:

• State laws vary and some states have stricter hemp regulations, meaning what’s legal in one airport might not be in another.
• Law enforcement may not know hemp laws. Even if your THCA flower is fully compliant, you might find yourself explaining federal hemp regulations to an officer who assumes all cannabis is illegal.
• If TSA finds flower, expect extra screening. Even if it’s under 0.3% THC, they can still flag it for law enforcement to handle.

At the end of the day, TSA’s focus is on security threats, not exactly drugs or weed, but if they do find cannabis flower, they can escalate it—and once law enforcement is involved, your trip could take a turn for the worse.

Our advice? Leave the THCA flower at home. But don’t worry—there’s always a solution.

As you can tell, traveling with THCA can be quite difficult. While you may not get stopped by TSA, there’s always the risk.

Your best solution? Ordering THCA flower online and shipping them to your destination. Don’t do the grunt work by packing it in your luggage and breaking a sweat at the airport. Let national shipments do it for you.
