While airport security is primarily focused on detecting explosives and knives, drug detection is also an important aspect of their work. Sniffer dogs are often employed to detect drugs, and their effectiveness has been demonstrated in various scenarios, including detecting drugs hidden in live plant shipments and on individuals. Additionally, intelligence plays a crucial role in drug detection, with certain itineraries or travel patterns potentially raising flags for drug trafficking. However, it's important to note that drug detection at airports may vary depending on the country and the procedures followed by their security and customs agencies.

Sniffer dogs: Trained to detect drugs, but can be fooled by certain scents like poinsettias
While sniffer dogs are trained to detect drugs, they can be fooled by certain scents, such as poinsettias. Poinsettias are mildly toxic plants that can cause a dog to experience mild irritation and digestive upset if ingested. The plant's milky white sap contains chemicals similar to those in household detergents, which can mask the scent of drugs and throw sniffer dogs off the trail.
In one instance recounted by a former general manager of multiple passenger airline cargo facilities, three sniffer dogs were unable to detect a baggie of weed hidden among live plant shipments. The drugs were tucked into a box of poinsettias, and the dogs were unable to pinpoint the location, even when narrowed down to the single pallet it was contained in.
Poinsettias are commonly associated with the holiday season and are often used in festive decorations. While their toxicity to dogs is not generally considered severe or fatal, it is important for pet owners to be cautious. Ingestion of large amounts of the plant can make a dog ill, so it is recommended to keep poinsettias out of reach and monitor pets closely during the holidays.
Despite the potential for poinsettias to distract sniffer dogs, it is important to note that drug detection at airport security involves a multitude of measures. Sniffer dogs are just one aspect of a comprehensive security system that includes technology, human inspection, and other methods to ensure the safety of passengers and prevent the illegal transportation of drugs and other contraband.
While the use of poinsettias to mask the scent of drugs may have worked in isolated incidents, it is not a guaranteed method to bypass drug-sniffing dogs. These dogs undergo rigorous training to detect a variety of drug scents, and their handlers are experienced in observing both the dogs' behavior and the behavior of potential suspects. Additionally, airports employ multiple dogs with different specialties, including those trained to detect explosives, further enhancing the security measures in place.

Itinerary flags: Drug trafficking origin or destination may trigger extra screening
Drug trafficking is a global issue that affects all parts of the world, and it is often associated with other forms of crime, such as money laundering, corruption, and the illegal trade of firearms, diamonds, and endangered species. As drug traffickers devise more creative ways to conceal their contraband, law enforcement agencies must adapt and enhance their detection methods.
At airports, Transportation Security Administration (TSA) officers are responsible for conducting security screenings of passengers, baggage, and cargo. While most TSA officers are not law enforcement officers, they have the authority to conduct searches and, if necessary, request additional screening. This additional screening may include a pat-down search or a request to remove certain items, such as a religious head covering. It's important to note that TSA officers cannot base their decision to conduct additional screening solely on factors such as race, national origin, religion, gender, ethnicity, or political beliefs.
To combat drug trafficking, TSA officers may employ various techniques and technologies. One common method is the use of K9 units, which are trained to detect drugs or explosives. These drug-sniffing dogs are often very effective, though they can be fooled on rare occasions, as scents can be masked by other strong odours.
In addition to K9 units, TSA officers may utilise advanced screening technologies, such as body scanners or chemical residue tests. They may also analyse passenger itineraries and look for suspicious travel patterns or destinations known for drug trafficking. If a passenger's itinerary raises red flags, they may be subjected to extra screening measures, including thorough searches of their person and belongings.
While the detection methods employed by TSA officers are designed to be thorough, drug traffickers are constantly devising new ways to avoid detection. This cat-and-mouse game between law enforcement and criminals highlights the dynamic nature of drug trafficking and the ongoing need for innovative countermeasures.

Intelligence: Border/customs agents use intel on flight origin and traveller's history
The Transportation Security Administration (TSA) works closely with intelligence agencies and law enforcement communities to share information and maintain the highest levels of transportation security. They adjust their processes and procedures to meet evolving threats and implement additional security measures from the time a passenger arrives at the airport until they reach their destination.
TSA's screening procedures are developed in response to information on threats to transportation security. They screen approximately 3.3 million carry-on bags daily for explosives and other dangerous items. Passengers are required to remove personal electronic devices larger than cell phones from their carry-on bags for X-ray screening. Certain items, such as powders in carry-on baggage, may require secondary screening, and those that cannot be resolved by security officials will be prohibited from the aircraft cabin.
The TSA also works with international partners to maintain aviation security standards abroad. The U.S. Department of Homeland Security has implemented enhanced security measures at foreign airports with direct commercial flights to the U.S., which may result in a more extensive screening process for passengers' property and personal electronic devices.
Additionally, the TSA relies on the traveling public to report any suspicious activities, such as unattended bags, individuals with threatening items, or persons trying to enter restricted areas. These measures are part of TSA's layered approach to security, ensuring the safe passage of passengers to their destinations.

Visual inspection: Security may perform searches based on suspicious behaviour or appearance
While airport security scanners cannot specifically identify drugs, they can detect them based on visual clues. For instance, drugs hidden under clothes or in baggage may be detected due to their unusual shapes or densities. Airport scanners can spot irregularities in shapes and layers, and drugs, especially when compressed, may show up as dense, opaque masses. The scanners flag any dense material that doesn't match the expected density of normal items.
Millimetre-wave scanners, a type of full-body scanner, can detect items concealed on a person's body. These scanners identify abnormalities based on density, shape, and the material's composition. They can spot drugs hidden in clothing or strapped to the body as they stand out against the natural contours of the human body.
If a person is suspected of swallowing drugs, they may be scanned with a full-body X-ray machine, which can detect packages in the person's stomach.
In addition to scanners, security personnel may also rely on visual inspection and suspicion to search individuals. For example, someone may be selected for additional screening due to their itinerary being flagged as a known origination point for drug trafficking. Other factors that may lead to a visual inspection include suspicious behaviour, appearance, or random checks. During these searches, security officers may investigate further if they notice something suspicious.
Drug detection dogs are also commonly used at airports to provide an additional layer of detection.

Technology: Scanners can detect some substances, but not always reliably
Airport scanners are designed to detect prohibited items, including illegal drugs. However, their effectiveness in detecting drugs depends on various factors, and they may not always provide conclusive evidence of drug possession.
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, often appear in shades of green or lighter colors on X-ray images, in contrast to metals, which show up as dark orange or blue. While X-ray scanners can provide visual clues about the presence of drugs, they cannot specifically identify them based on the image alone.
Millimeter-wave scanners are full-body scanners that can detect items concealed on a person's body. These scanners identify abnormalities based on density, shape, and material composition. Drugs hidden in clothing or strapped to the body may be visible due to their unusual shapes or densities compared to the natural contours of the human body. However, these scanners do not see under the skin, so they may not detect drugs hidden inside body cavities.
Trained security officers play a crucial role in interpreting scanner images and investigating suspicious organic materials further. Manual searches, drug detection dogs, chemical testing, and other specialized equipment are employed to confirm the presence of illegal substances.
It is important to note that drug detection at airports is not solely reliant on scanners. Border/customs agents may conduct checks based on factors such as the passenger's itinerary, appearance, and the origin of their flight. Additionally, drug detection dogs are used to provide an extra layer of detection.
