Travelling with vape pens and cartridges can be tricky, especially when it comes to THC vape pens. While the TSA does not actively search for drugs, they may turn you over to airport security if they notice something suspicious. Even in states where cannabis is legal, taking THC vape pens through airport security is not recommended as it could lead to confiscation, fines, or arrest. If you are travelling internationally, it is best to leave your THC vape pen at home, as many countries ban the import or use of vapes and have stringent laws against THC. However, if you are travelling domestically within the US, some sources suggest that you can take a THC vape pen through airport security by packing it in your carry-on bag and treating it like a nicotine vape pen. Nevertheless, it is important to research the specific regulations of the airline you are flying with and your destination to avoid any legal repercussions.

Vape devices are allowed in carry-on baggage, not checked baggage
If you're travelling with a vape device, you should be aware of the rules and restrictions surrounding their transportation. Vape devices are allowed in carry-on baggage, but not in checked baggage. This is a worldwide rule with no exceptions. This includes any vape device that contains lithium batteries. The reason for this is safety concerns over fires in the cargo hold. Lithium-ion batteries must not exceed a Watt-hour (Wh) rating of 100 Wh; for lithium metal batteries, the lithium content must not exceed 2 grams.
When travelling with a vape device, it's important to take effective measures to prevent the accidental activation of the heating element. This usually means turning off the power. Some sources recommend removing the batteries and storing them separately in a protective case. It's also recommended that you don't charge your vape device during the flight.
In addition to these safety measures, there are also restrictions on the liquids you can carry. All liquids, including e-juice and pre-filled pods, must be in containers no larger than 3.4 ounces or 100ml and must fit into a single 1-quart plastic bag. If you're bringing more e-juice than will fit in the allowed 1-quart bag, you can pack it in your checked luggage, but be sure to double-bag the bottles to prevent spills.
It's worth noting that the rules for cannabis vape devices are different and vary by country and state. While the TSA doesn't actively search for drugs, they will hand over any suspicious items to airport security, which is usually the local police. Even trace amounts of THC or residue can lead to confiscation, fines, or arrest. Therefore, it's recommended to avoid travelling with cannabis vape devices and to check the regulations of your destination country or state before travelling with any vape devices.

Lithium batteries pose a fire risk and are prohibited in checked luggage
Lithium batteries, which power many everyday devices, pose a significant fire risk if damaged or if their terminals are short-circuited. This risk is heightened in the cargo hold of an aircraft, where any fire is extremely dangerous. For this reason, lithium batteries are prohibited in checked luggage and must be transported in carry-on baggage.
The Federal Aviation Administration (FAA) has identified 620 verified incidents involving lithium batteries in the United States between March 2006 and April 2025. Of these, 465 occurred in the cabin and 129 in the cargo hold. The FAA expects the number of lithium battery fires to continue to increase as these batteries become more prevalent.
To reduce the risk of incidents, the FAA encourages passengers to check for recalls or damage to their devices, as these are more likely to create sparks or generate dangerous amounts of heat. Passengers should also protect their devices with sleeves or cases, which can prevent damage that could lead to thermal runaway.
In addition to the fire risk, lithium batteries in checked luggage can be subjected to extreme temperatures, pressure changes, and rough handling, all of which increase the likelihood of damage and subsequent thermal runaway. Therefore, it is essential that passengers adhere to the regulations and carry all devices containing lithium batteries, such as laptops, cell phones, tablets, and electronic cigarettes, in their carry-on baggage.

Vaping is banned in most airports and on flights, with severe penalties
Vaping is banned in most airports and on flights, with penalties ranging from confiscation to fines and arrest. This is because vaping devices are considered a security threat and a fire risk. While nicotine vapes are allowed in most places, they must be kept in carry-on luggage or pockets and are never allowed in checked luggage.
The rules for CBD and weed vape devices are stricter, as cannabis products, even small amounts such as residue in devices, are prohibited on all US flights and most international flights. Despite CBD's widespread legality, CBD airport arrests do occur. Even if you ultimately walk away, you could spend hours being questioned and waiting for your products to be tested.
The same goes for THC vape cartridges. While flying with them in the US is possible, it is not legal. For international flights, it is an even bigger issue. Once some countries see your pen, they will look for drugs. Pot is a banned substance in most countries, and you may be arrested for carrying it.
If you are going to take a vape through airport security, it is important to follow the TSA vape rules. All liquids must go into a single 1-quart bag, and all electronic devices and lithium batteries must be carried onto the plane and screened. To prove that your device isn't an explosive, TSA screeners may ask you to turn it on, so make sure it is charged.

TSA doesn't search for drugs, but will hand suspicious items to airport security
The Transportation Security Administration (TSA) does not actively search for drugs during security checks. However, if they notice something suspicious, they may turn you and your products over to airport security, which is usually the local police. Local authorities' responses vary depending on the legality of cannabis in that state or city. Even in places where cannabis is legal, you may still be subjected to an uncomfortable search, a long interview with security staff or police, and confiscation of your vape pens.
TSA officers are required to report any suspected violations of law to local, state, or federal authorities. While the TSA allows passengers to bring nicotine electronic cigarettes (vaporizers, vape pens, and ENDS) through airport security as carry-on items, they must be stored in carry-on baggage and not in checked baggage. This is because vape pens contain lithium batteries, which pose a fire risk to the cargo hold. Each lithium-ion battery must not exceed a Watt-hour rating of 100 Wh, and for lithium metal batteries, the lithium content must not be more than 2 grams. It is recommended to turn off the vape and remove the batteries, storing them separately in a protective case to prevent accidental activation. It is also important to note that vaping is banned in most airports and strictly prohibited on flights, with severe penalties for non-compliance.
If you are carrying liquids in your cartridge, they must be placed in a quart-sized bag for inspection at security checkpoints. TSA requires that liquid containers do not exceed 100ml (about 3.4 ounces) and that all liquids fit within a quart-sized transparent bag per person. It is important to note that federally controlled substances like cannabis products, even in small amounts such as residue in devices, are prohibited on all United States flights and most international flights.
Some sources suggest that the likelihood of being caught with a weed pen depends on the airport and the country. For example, when travelling from Europe to the US, some passengers report minimal checking beyond identity verification, while others mention drug-sniffing dogs or hand searches of carry-on luggage. International flights can be particularly problematic, as some countries have strict policies against cannabis and may profile travellers. It is also important to be aware that drug dogs are sometimes present and may detect even trace amounts of THC or residue, which could lead to confiscation, fines, or arrest.
In summary, while the TSA does not actively search for drugs, they may hand suspicious items over to airport security, and the consequences can vary depending on local laws and enforcement practices. To avoid potential legal issues, it is generally recommended not to travel with cannabis, THC, or vape cartridges containing these substances.

International travel with THC products, including hemp, is prohibited
While it may be tempting to take your THC vape pen with you when you travel, it is important to remember that international travel with THC products, including hemp, is prohibited. This means that taking your THC vape pen through airport security is not advisable, and could result in serious legal repercussions.
Firstly, it is important to understand that airports and aircraft fall under federal jurisdiction, regardless of the legality of cannabis in the state you are departing from or arriving at. This means that even if you are flying between two cannabis-friendly locations, you are still prohibited from carrying THC products, including vape pens, on your person or in your luggage. This is because, once you enter the airport, you are subject to federal laws, and can be charged with drug possession and transportation.
Secondly, while the Transportation Security Administration (TSA) does not actively search for drugs, they will turn you and any products they notice over to airport security, who will usually involve the local police. Even if you are ultimately released, this could result in you missing your flight, as well as causing a great deal of stress and inconvenience. In addition, some countries use drug-sniffing dogs at airports, which could increase your chances of being caught.
Thirdly, while it may be possible to conceal your THC vape pen by claiming it contains nicotine, this is not recommended. TSA screeners may ask you to turn on your device to prove it is not an explosive, and if they discover your pen contains THC, you will face the consequences outlined above. In addition, some sources suggest that it is illegal to lie to a federal agent about whether your vape pen contains cannabis.
Finally, while it may be possible to travel with certain hemp-based vapes that comply with federal regulations, it is essential to verify the THC content and ensure compliance with both federal and state laws before attempting to transport any vape gear. In addition, some countries, such as Canada, permit the possession of THC-infused items, but still prohibit crossing international borders with any cannabis products.
In conclusion, while it may be technically possible to take a THC vape pen through airport security, it is not recommended due to the serious legal risks involved. Instead, it is safer to buy and consume THC products at your destination, if they are legal there.
