If you plan to fly with CBD in 2025, the most important buying decision is to pick a product that includes a current, independent lab report showing THC at or below 0.3 percent. TSA screens for security threats, not drugs, but if a substance is discovered, local law enforcement can be called. That lab report is your first line of defense. Also, remember the TSA liquid rule for carry-on: containers must be 3.1 ounces (100 ml) or less. Choose travel-sized CBD tinctures or solid gummies to avoid issues.
Can You Bring Cannabis Through TSA? What US Federal Rules Say
What TSA Actually Says About Cannabis in 2025
TSA's official policy has not changed in 2025. Officers do not search for marijuana or other drugs. Their focus is on weapons, explosives, and other threats. If they find cannabis during routine screening, they will refer the matter to local law enforcement. That means the outcome depends on the laws at the airport, not on TSA.
- Marijuana with more than 0.3% THC remains illegal under federal law.
- Hemp-derived CBD with no more than 0.3% THC is federally legal.
- TSA allows CBD oil in carry-on and checked bags if it meets the hemp definition.
- State and local laws at your departure, arrival, and any connecting airports still apply.
