The circumstances were perfect: I was meeting up with one of my best friends from college for our first visit to Portland, Oregon, and held the eager anticipation of what kind of antics we would get into during the exciting weekend ahead. Yet, preparing for this short vacation led me to Google something I’ve never searched for before:

Is it legal to bring marijuana on a plane from one state to another if it’s considered legal in both states?

Most websites’ answers were a resounding, seemingly obvious “no.” Go ahead, laugh at my naivety all you want, but after spending most of my life in the Midwest where recreational marijuana legalization seems to be a far-off pipe dream, I honestly didn’t have a clue. Nor did I think it was a question I would ever have the opportunity to ask. Sure, I knew I could just buy whatever I wanted when I arrived in Portland, but after spending money on plane tickets, a few nights’ stay in a hostel, and knowing I had other pending expenses ahead, I didn’t want to drop even more cash on something I already had – legally.

SAVE MONEY: How to sprout your own marijuana seeds

I even took to Reddit to ask people on r/trees (if you haven’t checked it out, it’s a go-to subreddit for everything related to cannabis with over 1.3 million subscribers.) Most of the responses there ranged from caring – “I wouldn’t risk it, your weed will be waiting for you when you get back home :)” – to curt – “good luck getting caught and going to jail LOL.”

So, I went the safe route and left my edible gummies I was planning on bringing at my apartment and begrudgingly purchased more when I got to Portland. Still, I knew I wasn’t the only one questioning this legality. Whether you’re traveling to Portland like I was, or other big cities where recreational marijuana is legal – say, Seattle, Denver, Las Vegas, or Boston – it seems contradictory to have to leave your cannabis products at home when the law is giving you the green light in both your own city and destination.

That’s not to mention medical patients who need certain strains in order to combat chronic pain or alleviate symptoms of an illness. It was simple for me to just leave my weed at home, but what about patients for whom stopping usage can be detrimental to their health and well-being?

EXPLAINED: Here’s the science behind cannabis therapies for pain, inflammation

Long after I returned from the trip, I had the answer to my question, but still wanted the details. Are CBD products okay at airports? Is a TSA dog really going to sniff me out? Jenny L. Burke from the Transportation Security Administration provided me with some answers that might help you on your next journey.

The short answer:

As soon as you head into that airport, marijuana is considered a controlled substance and is therefore illegal from a federal perspective.

So, carrying a joint through the TSA checkpoint at a California airport is illegal?

Yes – but that doesn’t mean you’ll necessarily get in trouble if you get caught. TSA says that officers are required to report “any suspected violations of law, including possession of marijuana and cannabis infused products.” That being said, your weed likely isn’t their priority – the safety of everyone else is. TSA’s screening procedures are security-focused and designed to look for “potential threats” to aviation and passengers.

What about my CBD oil that I use for pain relief?

Yup, still illegal according to TSA guidelines. Again, they’re not looking for it though.  

What if I just kept my marijuana or CBD-infused products in my checked luggage?

This is also illegal in the eyes of the (federal) law which governs airports, and you don’t want to mess with the random searches that TSA conducts. Still, the searches there prioritize heavy metal objects and bottles full of liquid – frequent suspicious objects that call for further inspection again, for security reasons.

Do TSA dogs sniff for weed?

No. While some people think airport sniffer dogs will seek out illegal drugs, they’re predominantly trained to sniff for explosives, and to sniff for things that could introduce an invasive species into a foreign ecosystem. There’s more to it, though. Some dogs are trained to sniff for many drugs, but recent state court rulings on marijuana mean their keen noses for pot are no longer needed. They would return false positives on their work sniffing for other (illegal) drugs. They can’t always be counted on to smell the right thing, and some are actually being eased out of the labor force because of this.

The bottom line:

TSA officers are required to report any suspected violations of law, including possession of marijuana and cannabis infused products. While they don’t search for marijuana or other illegal drugs, in the event they find an illegal substance, they will refer the matter to a police officer to enforce state law. So, if you’re in a state where cannabis is legal, local officers are not likely to do anything, even as federal possession laws apply – as long as you don’t have eight pounds of weed chocolate.

It’s up to you to decide whether to play it safe or be a little daring, but you’re likely under less scrutiny than you might have previously perceived. Safe travels!
