The union representing state corrections officers says one of its members intercepted a package containing synthetic marijuana at the prison in Cape Vincent last week.
A news release from the New York State Correctional Officers and Police Benevolent Association says that a corrections officer working discovered the substance in a package addressed to an inmate.
The union says the officer discovered 12 granola bars that were wrapped in plastic and had been resealed in the original packaging.
When the officer opened the bars, he discovered a 54 grams of a green leafy substance that tested positive for synthetic marijuana.
The inmate, who is serving a three-year sentence for third-degree attempted sale of a controlled substance, faces disciplinary charges and an investigation is underway into who mailed the package.
