Although screening machines at airports are now very modern and advanced, detecting drugs hidden in luggage requires other technologies.
Many social media users wondered how the Import Baggage Procedures Team discovered the case when conducting inspection and screening operations. Currently, airports around the world have many ways to detect drugs hidden in luggage.

The primary goal of airport security personnel is to ensure safety. Therefore, the technologies used in scanning all have the basic feature of detecting weapons or dangerous items. Therefore, to detect drugs or banned substances will be more difficult.
According to lawyer Scott Welsch in London (UK), technically, the airport security scanners will not be able to directly detect drugs.
The job of the scanner is to help clearly show the goods and people passing through by X-ray technology (X-ray) , from which the screening staff will conduct a check with suspicious luggage. They can also ask customers to open their luggage and watch it live.
According to information from defensebridge, in addition to millimeter wave scanners, airports also use metal detectors and probes for security personnel to detect drugs. These devices are designed to collect small traces of metal, which can then alert authorities that something is wrong with the items in question.

The probes can also be used to further examine the contents of luggage, allowing the operator to see more detail without intruding on passenger privacy.
Defensebridge also said that ATI (Advanced Imaging Technology) is supposed to be the latest in security scanning technology. It creates a detailed image of hidden objects in the luggage and uses software algorithms for advanced analysis.
AIT is known to be more accurate than traditional security screening methods and better equipped to detect narcotics such as marijuana, cocaine and methamphetamine.
Finally, another measure to help detect prohibited goods at the airport is the Narcotics Trace Detection Equipment. Trace detectors are used to detect drugs or explosives in passengers’ luggage.
These machines work by releasing gas into containers such as suitcases and detecting the presence of substances that match those on the scanner’s library. The technology works to identify traces left over from explosives, drugs, pharmaceuticals and other materials that could pose a threat to aviation security.
X-ray baggage scanner is one of the devices used for security check at the airport to detect dangerous objects in hand luggage of passengers preparing to board the plane such as bombs, mines, weapons. hot gases or explosives.
According to information from Science Focus, X-ray technology emitted from one side of the machine is picked up by a pair of detectors on the opposite side. Luggage is placed on a conveyor belt, brought into the check-in cabin, which cuts the path of these X-rays and absorbs some of their energy.
This means that the X-rays passing through the furniture will transmit less energy than the remaining X-rays. By comparing the outputs of the two detectors, the machine can create an image showing the position and shape of the objects inside.

The objects inside are then distinguished by color. Specifically: Orange is for items made of organic substances such as plastic, paper or foods, while blue or green is used for metal and glass such as pliers, scissors, water bottles, etc.
Green or black are items that need attention and will be examined more closely, especially if the shape of the object bearing this color resembles that of weapons or other dangerous objects. The denser the material, the darker the color.
Explosives, incendiaries, weapons, guns; chemicals such as pepper spray, acid; objects with sharp blades or pointed ends; Working tools capable of causing injury… Are prohibited to bring on the plane.
It should be noted that simple everyday items such as fruit knives, razors, paper knives, scissors, toys that simulate weapons, etc. are also prohibited from carrying people or luggage up. passenger compartment.
