LAX vs. Federal Rules: What the LAX Marijuana Policy Really Means at Security

Short answer: LAX police follow California law on possession on airport property, but TSA screening is federal—if marijuana/THC products are discovered at the checkpoint, the matter can be referred to law enforcement. FlyLAX TSA

LAX states that, as of California’s legalization, adults 21+ may possess up to 28.5 grams of cannabis and 8 grams of concentrate. The Los Angeles Airport Police Division (APD) updated its procedures accordingly, and APD officers—who are California peace officers—do not have jurisdiction to arrest individuals who are complying with state law on airport property.

TSA screening is under federal jurisdiction. TSA’s official guidance notes that marijuana and certain cannabis-infused products remain illegal under federal law (with the narrow exception for items containing ≤0.3% delta-9 THC by dry weight or FDA-approved products). TSA officers focus on threats, don’t specifically search for drugs, but must refer suspected violations to law enforcement if illegal substances are discovered during screening. Ultimately, the final decision rests with the TSA officer at the checkpoint. TSA

Even if you depart a California airport that recognizes state possession limits, your destination’s laws do not change federal screening. Crossing state lines with marijuana remains illegal at the federal level, and TSA’s procedures and referral obligations apply at LAX just as they do elsewhere. TSA

If you’re traveling, the safest approach is not to carry THC products through the checkpoint. If you use CBD, understand that only products compliant with the federal ≤0.3% THC threshold—or FDA-approved medications—fit within TSA’s exception, and any discovery is still subject to officer review and potential referral. When in doubt, consider non-THC, travel-friendly options or plan to purchase legal products at your destination where permitted by local law. TSA

Yes, within California’s limits on LAX property, and APD has no jurisdiction to arrest if you’re complying with state law— but TSA screening is federal, and any discovery at the checkpoint can be referred to law enforcement. FlyLAX TSA

TSA doesn’t look for drugs, but if an illegal substance is found during screening, TSA will refer the matter to a law enforcement officer. Outcomes can vary based on the circumstances and applicable law. TSA

Policies vary by airport. LAX has publicly discussed the idea in the past, but travelers should confirm current options directly with LAX before flying; do not assume such boxes are available. City Clerk LA NBC Los Angeles
