A drug that is used to help addicts kick stronger drugs like heroin and painkillers has itself become a much abused substance. And one place it is winding up is in prisons where prisoners get it mailed to them, according to an article in The New York Times.
One popular way to smuggle Suboxone in is under stamps, or where a mixture is moistened and put on the back of stamps, for inmates to lick to get their high. Authorities in Maine, Pennsylvania and other states have caught on and now deliver the prisoner mail sans envelope.
Other ways the drug is smuggled is via a dried mixture used as a tint on children's coloring book pages. According to the article it is also found on thin strips in the overlapping seams of envelopes.
