"New York’s prison system unfairly punished more than 2,000 prisoners after tests of suspected contraband substances falsely tested positive for drugs, according to a report released Thursday. In hundreds of cases, the prisoners had committed no offense, but the flawed results were used to put them in solitary confinement, halt family visits, or cancel parole hearings."
"The Sirchie NARK II contraband screening tests are used to detect synthetic cannabinoids and other types of drugs by putting substances into testing pouches. They sometimes cross-react with commonly used over-the-counter medications, as well as tea or protein powders sold within some state facilities, the report detailed."
"In one case, officers used pen caps and pocketknives to place suspected contraband into the drug test kits, instead of using a clean loading device. That could have led to contamination of the test sample, leading to a false positive."
