Understanding the Regulations for Transporting Medical Marijuana and Other Substances

Transporting medical marijuana, even when it is legal in certain states, presents a complex challenge under federal laws. The Transportation Security Administration (TSA) clarifies that marijuana and cannabis-infused products, including Cannabidiol (CBD) oil, remain illegal under federal law unless they contain no more than 0.3 percent THC on a dry weight basis or are approved by the FDA, as outlined in the Agriculture Improvement Act of 2018. TSA officers must adhere to these regulations when inspecting items at checkpoints. For further details, refer to the TSA’s guidelines on Medical Marijuana.

The Federal Aviation Administration (FAA) issues a stark warning to pilots regarding the transportation of marijuana. Even if marijuana is legal in a state, federal law prohibits using aircraft to transport it. Non-compliance can result in severe penalties, including the loss of a pilot certificate and aircraft. For more information, see the FAA’s Marijuana Can’t Fly and Know the Rules and Penalties.

When it comes to alcohol, the TSA allows alcoholic beverages with more than 24% but not more than 70% alcohol in checked bags, limited to 5 liters per passenger in unopened retail packaging. Beverages with 24% alcohol or less face no limitations in checked bags. Miniature bottles of alcohol in carry-on must fit comfortably into a single quart-sized bag.

For tobacco products, the TSA permits them in both carry-on and checked bags. The final decision, however, rests with the TSA officer at the checkpoint. Learn more about what you can bring on a plane by visiting the Transportation Security Administration and Tobacco.

The U.S. Customs and Border Protection provides guidance on prohibited and restricted items. There’s generally no limit on the amount of fabric and clothing for personal use, but duties may apply if the personal exemption is exceeded. Unaccompanied personal shipments might have restrictions. For more information, visit their Prohibited and Restricted Items page.

When traveling with medications, the FDA advises carrying no more than a 90-day supply for personal use. If staying longer, consider additional regulations. For tips on traveling to the U.S. with medications, refer to the FDA’s guidelines.
