Suboxone, a drug used as treatment for opiate addiction, has become coveted as contraband in prisons, says the New York Times. Smugglers have turned crushed Suboxone pills into a paste and spread it under stamps or over children's artwork, including pages from a princess coloring book found in a New Jersey jail. The drug also comes in thin strips, which dissolve under the tongue, that smugglers have tucked behind envelope seams and stamps.
“It's become a crisis in here, to be honest with you,” said Francine Breton, administrator of the Cumberland County Jail in Portland, Me. “It's the drug of choice right now.” After Suboxone strips were discovered in two letters, the jail issued a new rule in March that all inmate mail must arrive in white envelopes. That way, officials can detect the orange tint of the strips when they hold an envelope up to the light. The jail rips stamps off every piece of mail before delivery after senders started putting a past made of crushed Suboxone pills on the back of stamps for inmates to lick off.
