Yes, you can travel with a portable dry herb vaporizer in your carry-on bag on US domestic flights, but you cannot pack it in checked luggage because TSA prohibits lithium-ion batteries below the cabin. Empty the chamber completely before traveling, do not carry any flower or cannabis product through TSA checkpoints regardless of state legality, and pack the device powered off. The TSA does not test or confiscate empty vaporizers, but local airport police at the destination may have different policies. International travel is more complicated. Many countries including Singapore, Thailand, Japan, and the UAE classify dry herb vaporizers as drug paraphernalia and impose serious penalties for possession. Even within Europe, rules vary by country. For LA travelers, LAX has no specific issue with empty portable vaporizers, and the same applies to Burbank and Long Beach airports. We recommend the Pax Mini, DaVinci IQC, or Arizer ArGo for travel because their compact form factors fit standard quart-sized liquid bags and look more like consumer electronics than traditional smoking devices.
