Common Products That Test Positive
Hand soaps that contain glycerin (Rinse very thoroughly after washing your hands.) Lawn fertilizers (Nitrates: Wash your hands and especially your shoes.)

Full-body scanners are used to detect threatening items and contraband such as weapons, explosives, and drugs under multiple layers of clothing. While there are a few different types of full-body scanners, the most common is the millimeter wave scanner.
By comparing the two detectors' outputs, the machine can construct an image showing not just the position of objects, but also roughly what they're made of and their density. Organic materials like paper, food and explosives are orange, while blue or green are used for metals and glass.
As shown in more detail below, this additional screening could be caused by things like: Your name matching a name of interest in a database. You raising suspicions while going through airport security. Your bag getting flagged when going through an x-ray machine.
Explosive Trace Detection (Swabbing)Screening officers may swab your carry-on baggage, clothing, shoes or laptop. When a trace of person is required, the screening officer will swab your hands, waist area and foot (or footwear) and then use ETD technology to test for explosives.
The magnetic field will be reflected back to the machine if there are any metal objects present, such as a watch or a belt buckle. The return signal is detected by the machine and a beeping noise is produced to alert the TSA agent.
The TSA largely looks for physical evidence that a passenger could be a threat, so they'll generally have no reason to search through the data on your phone. After all, they're the Transportation Security Agency, not a detective agency. Even if they did have reason to want to access your phone, they'd need a warrant.
The TSA drug tests are highly accurate, but they're not 100% accurate. Several things can affect the accuracy of these tests, including: The amount of urine you gave.
Full-body scanners identify both metallic and non-metallic items. However, these scanners cannot detect drugs inside the body. This is what makes these types of scanners different from medical X-rays.
While checked luggage is not routinely searched for drugs, there are still measures in place to identify suspicious or prohibited items, and if illegal items are found, there could be serious consequences.
“Millimeter wave imaging technology does not detect items inside a passenger's body or penetrate the skin,” Langston says. That said, Malvini Redden says body scanners would also not pick up anything else stashed inside a body cavity, such as drugs or hazardous liquids.
Metal detectors create a magnetic field by using a brief pulse of electrical current. The magnetic field will be reflected back to the machine if there are any metal objects present, such as a watch or a belt buckle. The return signal is detected by the machine and a beeping noise is produced to alert the TSA agent.
The answer is yes, airport scanners can detect cigarettes. Most airport scanners are equipped with advanced X-ray imaging technology that can detect items such as cigarettes. The scanners are also able to detect other items that may be concealed, such as drugs, weapons and other contraband.
In the US, TSA doesn't care about cigarettes as they are no hazard to aircraft operation. So there is no need to hide them. You can carry one book of safety matches or 1 lighter on your person, or in your carry on bags. Matches and lighters are prohibited in checked luggage in general.
