A Massachusetts man who admitted to smoking two ounces of pot a week while employed as a Boston firefighter for eight years has been sentenced to eight months in prison for cultivating marijuana in Bridgton.

Sean Berte, 32, of Roslindale, Mass., was sentenced Thursday by U.S. District Judge George Z. Singal following Berte’s guilty plea in February, according to a press release from the U.S. Attorney’s Office. He will be on probation for three years after serving his sentence.

The conviction stems from an investigation by the U.S. Drug Enforcement Administration and the Bridgton Police Department that found more than 100 plants growing at 111 Frost Farm Road May 29, 2009, as well as grow lights, timers, an exhaust vent and other devices for growing marijuana indoors, according to the U.S. Attorney’s Office.

“The Court noted that the defendant’s drug usage during his employment violated the respect and trust the public has in firefighters,” according to the release.

U.S. Attorney for Maine Paula Silsby said the conviction and sentence are significant because it sends a “strong message” that people who cultivate marijuana in Maine will be prosecuted and face stiff penalties.
