Yes, you can travel to San Marino with a vape pen in your carry-on bag. San Marino has no airport, so you will land in Italy and continue by road.

Can You Fly With a Vape Pen To San Marino?

Vaping Regulations

We could not find a law in San Marino that bans or specifically regulates e-cigarettes.

The Campaign for Tobacco-Free Kids' legal database has no e-cigarette rules on file for San Marino.

No law on file does not mean anything goes. Laws change, so check with the San Marino embassy or your airline before you travel.

Flying With Your Vape Pen

Vapes can fly, but only in your carry-on bag or on your person. TSA rules for vaping devices ban them from checked luggage.

You must take effective steps to stop the heating element from switching on by accident. Each lithium-ion battery must be 100 watt-hours or less, which covers almost all vape batteries.

The FAA says vapes must never be used or charged on the aircraft. Keep yours switched off or locked for the whole flight.

E-liquid in your carry-on follows the TSA liquids rule: bottles of 3.4 ounces (100 milliliters) or less, packed in one quart-sized bag.

These are US rules. Airlines elsewhere apply similar battery rules, so check with your airline before you fly.

Security Screenings

San Marino has no airport, so you clear security and arrival checks at an Italian airport. Italy's vaping rules apply while you are there.

Keep your vape and e-liquid where you can reach them in case screeners want to inspect them.

Conclusion

Bring your vape in your carry-on, follow Italy's rules on the way in, and check the local rules before you vape in San Marino.

Tips for Bringing a Vape Pen on a Plane

• 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, and only vape in airport areas where signs allow it.
• Never pack cannabis or THC products: they can break the law at your departure point, your destination, or both.
• Check the destination: we found no vape-specific law in San Marino, so check with the embassy and follow Italy's rules on your way in.
