A body cavity search, also known simply as a cavity search, is either a visual search or a manual internal inspection of body cavities for prohibited materials (contraband), such as illegal drugs, money, jewelry, or weapons. Body cavities frequently used for concealment include the mouth, vagina, and rectum. It is far more invasive than the standard strip search that is typically performed on individuals taken into custody, either upon police arrest or incarceration at a jail, prison, or psychiatric hospital. Often the procedure is repeated when the person leaves the institution. Body cavity searches may also be conducted at some international border crossings such as the U.S. Customs and Border Protection when they suspect international travelers of hiding contraband—such as drugs Procedure Many articles of contraband are concealable in the body's cavities, via means such as insertion into the rectum. Illegal drugs are often found in condoms and temporarily stowed in the colon, and cylinders such as Cigar Tubes are used to hide money, intravenous syringes, and knives. Duplicate handcuff keys could be concealed in many body orifices, such as in the nasal passages or underneath the tongue. In a thorough visual body cavity search, a flashlight is used to illuminate common bodily areas, including the nostrils, ears, mouth, navel, penis (urethra and foreskin) or vulva, and buttocks. Generally, the detainee is required to cooperate with manipulating these body parts as they are examined. Squatting is sometimes instructed during the visual search, and prolonged holding of a squat can be demanded; squats are sometimes demanded while standing over a mirror (so that the observer has an improved view). The person may be asked to “squat and cough,” with the aim of dislodging an object stored in the rectum or vagina. During manual body cavity searches, an inmate is temporarily transferred to an offsite clinic to be examined by a licensed physician of the same sex; body orifices are probed using fingers or instruments. The circumstances in which these inspections may be done are often restricted, such as on individuals refusing to offer to consent to a visual body cavity search for reasons other than anxiety or in situations where there is a strong evidence to suspect the presence of contraband, and require a court order. As cavity searches have proven as an ineffective strategy in the total prevention of smuggling objects as it cannot detect objects in the intestines or
