What do airports look for in luggage?

Technically, airport security scanners do not detect drugs but they can provide visual clues of drugs hidden under the clothes and in baggage. Even if the scanners cannot determine the exact composition, they can tell if an object is organic or metallic or how low or high density an object have.



Airport security and customs use advanced X-ray and CT scanners to look for three primary categories: threats, prohibited items, and contraband. Security scanners (TSA) are primarily looking for "threats" like explosives, weapons, and incendiary devices; they detect these based on the density and atomic number of materials, with organic materials appearing orange and metals appearing blue or green on their monitors. They also look for high volumes of liquids that exceed the 100ml rule. Customs (CBP), on the other hand, look for "contraband" such as illegal drugs, undeclared currency (typically over $10,000), and agricultural products like meat, fruit, or soil that could carry invasive pests. In 2026, AI-integrated scanners are even better at spotting "anomalies," such as bundles of cash or hidden compartments. If an item looks unusual or dense on the screen, a manual bag search is triggered. Always remember that items like lithium batteries and power banks are flagged because they are fire hazards and must stay in your carry-on luggage.
