Airport scanners are used to detect anything that may put lives in danger, such as weapons or explosives. They can detect both metallic and non-metallic objects, and even small amounts of metal. However, they cannot identify specific objects and do not detect drugs directly. Instead, they provide visual clues about the contents of baggage and can indicate the presence of organic materials, which are marked in orange. If drugs are suspected, security officers may use other methods, such as swab tests, sniffer dogs, or full-body X-ray machines, to confirm the presence of drugs.

Airport scanners can detect metallic and non-metallic objects
Airport scanners are designed to detect a wide variety of materials, including metallic and non-metallic objects. Metal detectors and millimetre-wave machines use low-energy, non-ionizing radiation to generate images that show objects on a person's body or in their luggage. If there are no weapons or other potential threats, the screen turns green and shows an "OK". If an object is detected, it will appear on the screen with a generic body outline to indicate its location.
While metal detection remains a priority, non-metallic materials are increasingly being used to create weapons and other threats. Advanced X-ray scanners can identify items made of plastic or ceramic by analysing their shape, density, and other visual cues. Airport scanners are also designed to flag liquids, gels, and aerosols that exceed certain volume limits.
Millimetre-wave scanners can detect both metallic and non-metallic items, including weapons, explosives, and drugs hidden under clothing. They are ideal for large-scale use in airports because they are non-invasive. Passive infra-red scanners are another type of scanner that can detect metallic and non-metallic "threat objects" without using an external radiation source, thus preserving privacy.
Although airport scanners can detect metallic and non-metallic objects, they do not always identify what these objects are. For example, scanners can tell if an object is organic or metallic and determine its density, but they do not detect drugs. Instead, the X-ray image they produce can be used by security agents to decide whether a passenger poses a threat and should undergo further screening.

Scanners cannot detect drugs by themselves
Scanners at airports are designed to detect threats, such as weapons or explosive materials, and other items that violate carry-on rules. They can detect both metallic and non-metallic objects, including organic materials. However, they cannot, by themselves, detect drugs or other illegal substances.
While airport scanners can detect the presence of organic materials, they cannot identify the specific substance. For example, they can detect that an object is organic, but not that it is cocaine or prescription medication. This means that, while scanners may provide visual clues about the presence of drugs, they do not identify drugs by themselves.
Instead, the detection of drugs relies on the skills and interpretation of security officers. Security agents interpret the images produced by the scanners and decide whether a passenger or their luggage warrants further investigation. If a passenger is suspected of carrying drugs, they may be subjected to additional screening procedures, such as a pat-down or a full-body X-ray scan.
Additionally, airports may employ other methods to detect drugs, such as sniffer dogs, chemical or electronic swab tests, and trace portal machines. These methods complement the use of scanners and help improve the accuracy of drug detection. Therefore, while airport scanners play a role in security by detecting potential threats, they do not have the capability to specifically identify drugs without the intervention of trained security personnel.

Scanners can detect organic materials
Scanners at airports are designed to detect a wide range of materials, from metals to plastics and organic compounds. They can identify the density and mass of objects in luggage, and while they may not always be able to establish what the objects are, they can tell if something is organic, metallic, or how low or high density it is. Organic materials are marked with an orange colour.
The most common type of scanner found in airports is the ATI or attenuation imaging scanner. These are designed to guarantee privacy and only show a generic outline. They can detect non-metallic objects and are useful for detecting explosives and drugs.
Advanced imaging technology provides an X-ray image that TSA officers can use to decide if a passenger poses a threat. The security agent can then take the passenger for a more comprehensive security process. Millimeter-wave scanners are used to detect objects concealed on a person's body.
Modern luggage scanners use 3D imaging technology, allowing security personnel to view objects from multiple angles and identify hidden compartments. Some scanners are equipped with software that enhances the detection of non-metallic threats, making them highly effective in preventing smuggling attempts.

Scanners can detect if drugs are swallowed
Airport scanners are designed to detect anything that may put lives in danger, such as weapons, and identify objects that are not legal. While airport scanners cannot specifically detect drugs, they can provide visual clues of drugs hidden under clothes, in baggage, or swallowed.
Full-body scanners, for example, can detect items concealed on or inside a person's body without physically removing clothes or making physical contact. These scanners can identify non-metal objects, such as drugs, strapped to the body or hidden in clothing due to their ability to detect unusual shapes or
Millimetre-wave scanners, a type of full-body scanner, use non-ionizing electromagnetic radiation to generate images. These scanners do not identify gender or body type but can detect items that stand out due to abnormal density, shape, or composition. For example, drugs, especially when compressed, may appear as dense, opaque masses on scanners, which would prompt further investigation.
In addition to millimetre-wave scanners, X-ray scanners are commonly used to screen baggage. These scanners can detect objects with different densities and differentiate between organic materials, metal, and plastic. Organic materials, such as drugs, are marked with an orange colour. If a suspicious object is detected, security personnel may use portable chemical detection kits to test for the presence of drugs.
While airport scanners have advanced technology, they may not always be able to identify drugs hidden in creative ways. However, the combination of scanning technology and skilled security officers helps maintain safety and combat drug smuggling at airports.

Airports use other methods to detect drugs
While airport scanners can detect metallic and non-metallic objects, they do not specifically look for drugs. Instead, they identify anomalies or suspicious items based on density, shape, and material composition. For example, drugs, especially when compressed, may show up as dense, opaque masses on scanners, which will then be flagged for further inspection.
However, there are other methods that airports use to detect drugs, which include:
- Millimeter-wave scanners: These full-body scanners can detect items concealed on a person's body. Drugs hidden in clothing or strapped to the body are visible to these scanners as they detect unusual shapes or densities that stand out against the natural contours of the human body.
- X-ray scanners: These scanners are used for screening baggage and can detect objects with different densities, including drugs hidden in luggage. Organic materials, such as drugs, appear differently on X-ray images compared to metal or plastic.
- Chemical testing: If something suspicious is found, a small sample may be taken for immediate testing using portable chemical detection kits, which can identify various substances, including drugs.
- K9 units: Drug-sniffing dogs are often used at airports to detect the presence of drugs. These dogs are trained to track down drugs hidden in various locations, including cargo, luggage, and on individuals.
- Trace portal machines: These portals are primarily used for detecting explosives but can also be useful for detecting drugs, as they can detect non-metallic objects.
These additional methods provide a more comprehensive security process to detect drugs and ensure the safety of passengers and staff at airports.
