Travelling with a vape can be confusing, especially with different airline policies and security regulations worldwide. If you’ve ever wondered, can you take vape juice on a plane, the short answer is yes—but you need to follow specific guidelines. Whether it’s regular e-liquid or CBD vape juice, understanding the rules ensures a smooth journey through airport security.
Let’s go through everything you need to know about taking vape juice on a flight, including carry-on rules, checked luggage restrictions, international travel considerations, and what happens if your vape juice contains CBD.
Understanding Airline Rules for Vape Juice
Most airlines and aviation authorities allow passengers to carry vape juice in both carry-on and checked luggage, but there are restrictions. The 3-1-1 rule applies to all liquids in carry-on bags, meaning:
- Each container must be 3.4 ounces (100ml) or less
- All containers must fit in one quart-sized resealable plastic bag
- Each passenger is allowed one liquid bag
If you’re carrying more than 100ml of vape juice, it must be placed in your checked luggage. However, be cautious—checked luggage is subject to temperature and pressure changes, which might cause bottles to leak or burst. Sealing them in plastic bags can help prevent spills.
Can You Take CBD Vape Juice on a Plane?
If your vape juice contains CBD (cannabidiol), additional rules may apply. In the UK, CBD e-liquids are legal as long as they contain less than 0.2% THC. However, international laws vary. Some countries—such as the United Arab Emirates, Singapore, and Thailand—ban all forms of CBD, even if they are THC-free.
Before travelling with CBD vape juice, check the laws of your destination. While you can often carry CBD e-liquids on domestic UK flights, travelling internationally with CBD can lead to confiscation or legal trouble if the country has strict cannabis laws.
Packing Vape Juice in Your Carry-On vs. Checked Luggage
Bringing Vape Juice in Carry-On Bags
Many travellers prefer keeping vape juice in carry-on luggage to prevent leaks due to pressure changes in checked bags. When packing vape juice in your hand luggage:
✔ Follow the 3-1-1 liquid rule (100ml bottles max, stored in a resealable plastic bag)
✔ Keep it easily accessible for security screening
✔ Ensure the bottle is tightly sealed to prevent leaks
For CBD vape juice, be ready to show product labels or lab reports proving THC content is below 0.2% if requested by security.
Bringing Vape Juice in Checked Luggage
Larger bottles of vape juice must be stored in checked baggage, but be aware of potential leakage risks. To prevent spills:
- Wrap bottles in plastic bags for extra protection
- Avoid overfilling bottles, as pressure changes can cause expansion
- Use padded cases to prevent bottle breakage
