Airport scanners are an essential tool in detecting illegal objects and play a vital role in identifying prohibited items that could be dangerous to aviation safety. They can detect metallic and non-metallic objects, as well as organic materials, such as food, paper, and drugs. While airport scanners cannot directly identify drugs, they can provide visual clues about the presence of narcotics. They can detect drugs based on their density, composition, and packaging, flagging items for further inspection by trained security officers. Additionally, passengers suspected of swallowing drugs may be scanned with a full-body X-ray machine to detect packages in their stomachs.

What You'll Learn
Airport scanners can detect organic materials
Airport scanners are designed to detect metallic and non-metallic objects, including organic materials. They can identify drugs, which have unique densities and compositions that stand out on an X-ray scan. Organic materials like food, paper, or drugs appear as shades of green or lighter colours.
Airport scanners can detect drugs hidden in luggage or on a person's body. For example, millimetre-wave scanners can detect drugs hidden in clothing or strapped to the body by identifying unusual shapes or densities that stand out against the natural contours of the human body. Similarly, backscatter X-ray scanners can detect drugs hidden under clothing or in luggage by identifying the densities of different objects. These scanners can also detect false bottoms or secret compartments in luggage, which may be used to conceal drugs.
Additionally, airport scanners can detect drugs swallowed by passengers. Full-body X-ray machines can identify packages in a person's stomach, even if the drugs are contained in plastic, non-metallic, or metallic bottles.
While airport scanners can detect organic materials and provide visual clues about the presence of drugs, they cannot determine the exact composition of the substances. Trained security officers examine flagged items further through manual searches or with the help of drug detection dogs.

They can identify unusual shapes or densities
Airport scanners are highly skilled at spotting unusual shapes or densities that could indicate the presence of drugs. While they don't specifically "look" for drugs, they can detect items with different densities, including drugs hidden in luggage. This is because drugs have unique densities and compositions that stand out on an X-ray scan.
Millimeter-wave scanners, for example, can detect unusual shapes or densities that stand out against the natural contours of the human body. This makes them effective at detecting drugs hidden in clothing or strapped to the body. Similarly, X-ray scanners used for screening baggage can detect the densities of items within luggage and identify organic materials, including drugs.
Airport scanners can also detect hidden compartments or false bottoms in luggage, which are commonly used to conceal drugs. The scanners emphasize the edges of items, allowing security officers to easily identify illegal objects. Additionally, they can detect drugs hidden inside everyday objects, such as books, shoes, or electronics, by spotting irregularities in the scanned images.
While airport scanners can provide visual clues about the presence of drugs, the interpretation of these clues depends on the skills and experience of the security officers reviewing the scans. Trained security officers can study the images and conduct further inspections if necessary, using methods such as manual searches or drug-detection dogs to confirm the presence of illicit substances.

Scanners can detect drugs in the stomach
Airport scanners are highly skilled at spotting drugs and can provide visual hints that might suggest the presence of narcotics. They can detect drugs hidden in luggage, even in everyday items such as books, shoes, or electronics, as well as false bottoms or secret compartments in bags. This is because they can identify objects with different densities, and drugs have unique densities and compositions that stand out on an X-ray scan.
However, airport scanners do not specifically look for drugs. They are designed to identify prohibited items that could be a danger to aviation safety. When drugs are detected, it is usually because they are flagged as anomalies by the scanner, which then requires further examination by trained security officers. This may involve a manual search of the bag or the use of drug detection dogs.
While airport scanners are very effective at detecting drugs in baggage, they may not always detect drugs in the human body. Millimeter-wave scanners, for example, can detect unusual shapes or densities hidden on a person's body or in their clothing. However, these scanners are primarily looking for items that could pose a threat to aviation security, such as weapons or explosives.
That being said, passengers who are suspected of swallowing drugs may be scanned with a full-body X-ray machine, which can detect packages in the stomach, even if they are contained in non-metallic or metallic bottles. These scanners are sensitive enough to identify pills or liquids that a person may be travelling with, regardless of their packaging. Therefore, while airport scanners may not specifically target drugs in the stomach, they can indeed detect them if suspicions arise.

They can detect drugs hidden in everyday objects
Airport scanners are highly skilled at spotting drugs and can detect drugs hidden in everyday objects. They can provide visual clues of drugs hidden under clothes and in baggage. X-ray scanners can detect objects with different densities, including drugs hidden in luggage. They can also detect unusual shapes or densities that stand out against the natural contours of the human body.
While airport scanners cannot directly detect drugs hidden inside luggage, they can easily spot a substantial amount of organic substances in luggage through simulated images. The scanners emphasize the edges of an item, allowing security officers to see through the things inside the bag and identify any illegal objects more easily.
Millimeter-wave scanners, for example, can detect drugs hidden in clothing or strapped to the body. Similarly, passengers suspected of swallowing drugs are scanned with full-body X-ray machines that can detect packages in the stomach, even if the pills are contained in plastic, non-metallic, or metallic bottles.
Additionally, hiding drugs in everyday objects like books, shoes, or electronics may work against less sophisticated screening methods, but modern airport scanners can typically detect these hidden compartments. False bottoms or secret compartments in luggage will also likely be caught by X-ray scanners, which will flag the item for further inspection.

Trained dogs are used to detect drugs
Airport baggage scanners use advanced technology to identify organic materials and detect substances like drugs and explosives, which have unique densities and compositions that stand out on an X-ray scan. They can also detect metallic and non-metallic objects. While airport scanners can identify suspicious items and anomalies, they do not specifically look for drugs. Further inspection by trained security officers is required to confirm the presence of narcotics.
To enhance drug detection capabilities, airports often employ trained canines, commonly known as drug detection dogs or sniffer dogs. These dogs are skilled at using their sense of smell to detect illegal drugs, explosives, and other contraband items. Their ability to sniff out drugs provides an extra layer of security at airports.
The training process for drug detection dogs involves teaching them to associate a specific scent with a reward. The dog learns a simple command, such as "sit" or "bow," along with a hand signal or clicker. They are then exposed to a sample scent and rewarded when they respond correctly. This process is repeated until the dog can identify the scent automatically. The next step is to hide the scent and have the dog find it, gradually increasing the difficulty.
The effectiveness of drug detection dogs has been the subject of debate. Some studies show varying levels of accuracy, with factors such as breed, training level, type of drug, and search environment playing a role. German Shepherds, for example, have been found to give more correct indications than Terriers. Additionally, the presence of residual odors and potential biases of handlers can impact the accuracy of drug detection dogs.
Despite some uncertainty regarding their effectiveness, drug detection dogs remain a valuable tool for law enforcement and security services, providing an additional layer of protection against drug smuggling and ensuring the safety of passengers and aircraft.
