Can you bring your vape pen to Guam? Here are the flight rules, Guam's vaping laws and tips for flying with a vape pen.

Can You Fly With a Vape Pen To Guam?

Vaping in the Air

Yes, you can fly to Guam with a vape pen, as long as it travels in your carry-on bag or on your person.

Guam is a US territory. Vapes are legal there for adults 21 and over.

What you can't do is use it. Vaping is banned on commercial flights, and the FAA calls it dangerous and a federal offense on US flights.

You also can't charge your vape on board. Some airports have smoking areas where vaping is allowed, but rules vary, so follow the signs.

What You Can Bring Along

The TSA allows vapes in carry-on bags only, with lithium ion batteries of 100 Wh or less. Spare batteries must also go in your carry-on, with the terminals covered.

Nicotine e-liquid is allowed in the cabin. Bottles must be 3.4 ounces (100 milliliters) or less and go in your quart-sized liquids bag.

Never pack cannabis, THC or CBD products. Many countries treat them as illegal drugs.

Allowed In Checked Luggage?

No. Vapes and spare lithium batteries are banned from checked luggage, because they are a fire risk in the cargo hold.

If your carry-on is checked at the gate, take your vape and spare batteries out and keep them with you.

Are Vape Pens Illegal in Guam?

Vaping Laws in Guam

Vape pens are legal in Guam for adults 21 and over. Guam defines e-cigarettes as tobacco products and raised the minimum age for all tobacco to 21 on January 1, 2018.

That matches federal Tobacco 21 law, which bans selling e-cigarettes to anyone under 21 in the US.

Where Is Vaping Permitted?

Since 2019, Guam's smoke-free law (the Natasha Protection Act) bans e-cigarettes wherever smoking is banned, according to Guam's tobacco control mandates.

Guam also bans e-cigarette sales from vending machines, and a 2024 law raised penalties for selling to minors.

Be Discreet

Follow no-smoking signs, and ask before you vape in hotels, restaurants or rental cars.

Tips for Bringing a Vape Pen on a Plane

With a bit of preparation, flying with a vape pen is simple. Here are some tips:

• Carry-on only: pack the vape and any spare batteries in your carry-on. If your bag is gate-checked, take them out first.
• Prevent activation: switch the device off or lock it, and keep spare batteries in a case away from keys and coins.
• Liquids: keep e-liquid bottles at 3.4 ounces (100 ml) or less, in your liquids bag. Pressure changes can make tanks leak, so carry them empty or in a sealed bag.
• No vaping on board: don't use or charge your vape on the plane.
• Check every stop: airlines can limit how many devices you carry, and the rules of any country where you change planes also apply.
