So this guy from East Boston strikes up a conversation with another guy sitting on a bench in the busway at Andrew station this afternoon. He's feeling mellow, gets a joint out of his right jacket pocket, lights up and offers his newfound friend a toke.

Unfortunately for the man, the guy was an undercover Transit Police officer, assigned to anti-drug duty at the South Boston station, police report.

Transit Police report the officer summoned other officers and they confiscated the man's cigarette - and the two additional bags of pot he had in his pocket. Fortunately for him, he was holding less than an ounce, so he was only issued a $100 citation, police say.
