Airport scanners are an essential tool in maintaining aviation safety and security. They are designed to detect metallic and non-metallic objects, including weapons and explosives, by differentiating materials based on their density and atomic number. While airport scanners do not specifically look for drugs, they can detect organic materials, which may include drugs such as heroin, cocaine, marijuana, and methamphetamine. These substances often appear as shades of green or lighter colours on X-ray images. Additionally, full-body scanners can identify unusual shapes or densities on a person's body, indicating potential drug concealment. Sniffer dogs and random checks by border/customs agents further enhance drug detection at airports.

What You'll Learn
X-ray scanners can detect methamphetamine in luggage
Airport baggage scanners are designed to ensure the safety of air travel by meticulously inspecting the contents of travellers' luggage. These scanners use X-ray radiation to see through luggage and assess its contents without opening it. X-ray scanners can detect objects with different densities, including drugs hidden in luggage. While scanners cannot specifically identify drugs from an image, organic materials, such as drugs, appear differently on X-ray images compared to metal or plastic. Drugs made from organic compounds like heroin, cocaine, or marijuana often have distinct signatures.
X-ray scanners can detect even the smallest amount of metal and can detect paper. They can also differentiate between various substances, from metals to organic materials such as food, liquids, and even detect indications of organic materials like drugs. The scanners will flag items that look different from the norm. For example, if currency is arranged in bundles, it will be more easily detected.
X-ray scanners can also detect irregularities in shapes and layers. For example, if drugs are concealed in irregular packaging, such as within electronics or hollowed-out items, they can stand out during an X-ray scan. X-ray scanners can also detect false bottoms or secret compartments in luggage, as these irregularities will be flagged for further inspection.
While X-ray scanners cannot specifically detect methamphetamine, they can detect organic materials and irregularities in luggage that may indicate the presence of drugs. Trained security officers will investigate any suspicious organic material or anomalies further, including conducting manual searches of luggage and utilising drug detection dogs.

Full-body scanners can detect drugs on a person's body
Airport scanners are an essential tool in detecting illegal objects and play a crucial role in maintaining aviation safety. While they do not specifically look for drugs, they can provide visual clues of drugs hidden under clothes and in baggage.
Full-body scanners use millimeter waves and backscatter technology to see detailed images under clothing. They detect items concealed on a person's body by identifying abnormalities or suspicious items based on density, shape, and material composition. Drugs, especially when compressed, may show up as dense, opaque masses on scanners. The software flags any dense material that doesn't match the expected density of normal items. For example, the natural contours of the human body differ from the density of drugs hidden in clothing or strapped to the body.
Additionally, organic materials, such as drugs, food, explosives, or paper, are marked with an orange color on the scanner. This helps security personnel identify potential threats and investigate further. If an anomaly is detected, a manual search may be conducted, where officers will physically inspect the item to determine if it contains illicit substances.
It is important to note that some drugs may be ingested or hidden within body cavities. In such cases, full-body X-ray machines can detect these objects as they differ in density from normal tissues. Overall, the sophisticated technology of full-body scanners plays a vital role in combating drug smuggling and ensuring aviation security.

Scanners can't identify drugs, but flag anomalies for further inspection
Airport scanners are designed to detect prohibited items, including illegal drugs, to ensure flight safety. While they cannot specifically identify drugs, they can flag anomalies for further inspection.
X-ray scanners are commonly used to screen baggage and can detect objects with different densities, including drugs hidden in luggage. Organic materials, such as drugs, food, and explosives, appear differently on X-ray images compared to metal or plastic. They show up as shades of green or lighter colors, while metals appear as dark orange or blue. However, X-ray scanners cannot directly detect drugs hidden inside luggage and instead rely on simulated images to spot large amounts of organic substances.
Millimeter-wave scanners are full-body scanners that detect items concealed on a person's body. They can identify unusual shapes or densities that differ from the natural contours of the human body, such as drugs hidden in clothing or strapped to the body. These scanners also do not specifically look for drugs but identify suspicious items based on density, shape, and material composition.
Airport scanners also employ advanced technology to identify organic materials. They can distinguish between various substances and detect indications of drugs through their distinct signatures. While scanners cannot identify drugs from an image alone, trained security officers will investigate flagged items further. This may include manual searches, the use of drug detection dogs, or chemical testing with portable kits.
It is important to note that airport security scanners primarily focus on detecting explosives and weapons to ensure the safety of air travel. The detection of drugs is often handled by border or customs agents, who may rely on factors such as flight origin, travel history, and random checks in addition to scanner results.

Organic materials appear as shades of green or light colours on scanners
Airport scanners are designed to detect prohibited items, including illegal drugs. There are different types of scanners used at airports, each designed for a specific purpose. X-ray scanners, for instance, can detect objects with different densities, including drugs hidden in luggage.
While airport scanners don't specifically look for drugs, they can identify abnormalities or suspicious items based on density, shape, and material composition. Organic materials, such as drugs, food, explosives, or paper, are marked with an orange colour on the scanners. Drugs, especially when compressed, may show up as dense, opaque masses, and the scanner software will flag any dense material that doesn't match the expected density of normal items.
Millimetre-wave scanners, another type of scanner used at airports, can detect items concealed on a person's body. These scanners work by identifying unusual shapes or densities that stand out against the natural contours of the human body. They can detect drugs hidden in clothing or strapped to the body.
Additionally, airport scanners can detect anything that is not a part of the human anatomy and can spot things concealed under clothes and layers. They can also detect the smallest amounts of metal and paper. Money, for instance, will be detected more easily if it is arranged in bundles.
While scanners can provide visual clues about drugs hidden in baggage or under clothing, they cannot always determine the exact composition of suspicious items. In such cases, trained security officers will investigate further, conducting manual searches, utilising drug detection dogs, or performing chemical tests on small samples.

Sniffer dogs are used to detect drugs at airports
While airport scanners can detect drugs, they do not specifically look for them. Instead, they identify unusual shapes, densities, and compositions. For example, drugs may show up as dense, opaque masses on scanners, or their irregular packaging may be flagged.
However, sniffer dogs are also used at airports to detect drugs. These dogs are trained to recognize a wide range of scents and can identify narcotics with nearly 90% accuracy. They work in silence, covertly inspecting passengers, luggage, and cargo areas for drugs, explosives, and firearms. The use of sniffer dogs ensures passenger safety and compliance with laws.
Drug-sniffing dogs are permitted at checkpoints, including airports, to enforce drug control laws and prevent drugs from crossing borders. They work alongside their handlers, who are trained to handle the dogs and conduct further investigations when the dogs identify a suspect. The dogs may give a silent cue, such as sitting down next to a suspect's bag, to indicate that they have detected something.
The Transportation Security Administration (TSA) in the United States reported in 2022 that canine teams are present at major US airports, with over 900 teams operating nationwide for drug and explosives detection. The TSA Canine Training Center ensures that dogs meet strict federal standards before deployment.
In addition to drug detection, sniffer dogs at airports may also be trained to detect explosives, firearms, contraband, and agricultural goods. They play a crucial role in maintaining security and preventing terrorism.
