A drug bust Friday in Massachusetts turned up more than 1,000 bags of heroin stamped with “Obamacare.”

A Massachusetts state trooper pulled over a car that passed him on a highway in Hatfield, Mass., early Friday morning after noticing the vehicle making “several violations,” according to the Massachusetts State Police.

During the stop, a trooper and a K9 found 1,250 individual bags of heroin that were stamped with “Obamacare,” a reference to the Affordable Care Act. It’s unclear why the drugs were marked with the phrase.

Four people were arrested in connection with the incident and charged with narcotics violations, according to the Massachusetts State Police Facebook account.
