TSA Rules for Marijuana in Your Bag 2025

The short answer on TSA and marijuana in 2025

If you plan to fly, do not buy marijuana to bring on the plane. TSA rules for marijuana in your bag in 2025 remain strict because marijuana is illegal under federal law. TSA will refer any marijuana found during security screening to local law enforcement. The only cannabis product TSA allows is hemp-derived CBD with no more than 0.3% THC, and even that can lead to problems. Buy your cannabis at your destination if it is legal there.

What to look for before you pack

Before you buy any cannabis product for a trip, check three things. First, check federal law. Marijuana is a Schedule I controlled substance. Second, check state law where you are flying from and to. State legalization does not override federal law at airports. Third, check the product label for THC content. Hemp and marijuana are the same plant, but the law separates them by THC concentration.

Federal vs state law

Airports and airplanes fall under federal jurisdiction. TSA officers are federal employees. They follow federal rules, not state cannabis laws. Even if you fly between two legal states, you cross federal airspace. That makes possession a federal issue.

Hemp vs marijuana

Hemp is defined as cannabis with 0.3% THC or less. Marijuana is cannabis with more than 0.3% THC. TSA allows hemp-derived CBD products in carry-on and checked bags if they meet the 0.3% THC limit. However, TSA does not test for THC. Local law enforcement may test. If the product exceeds the limit, it is treated as marijuana.

Parameter bands for THC content

Use these bands to understand what you are buying and how it relates to TSA rules.

• 0.3% THC or less: Hemp. TSA allows these products. Keep them in original packaging with a label.
• More than 0.3% THC: Marijuana under federal law. TSA will refer you to law enforcement. Do not pack it.
• No label or unknown THC: Risky. TSA or police may assume it is marijuana. Avoid.

Pitfalls to avoid

Many travelers make mistakes that turn a simple trip into a legal problem. Avoid these pitfalls.

1. Assuming state law protects you at the airport. It does not.
2. Packing marijuana in checked bags. TSA screens checked bags too.
3. Bringing homemade edibles or vape cartridges without labels. They look suspicious.
4. Thinking TSA will ignore a small amount. Any amount is a federal violation.
5. Buying a product labeled "CBD" without checking THC content. Some products mislabel.
