BERLIN, GERMANY - SEPTEMBER 20: Elderly women play a cards game of rummy at the Mireille Mathieu senior citizens' center on September 20, 2017 in Berlin, Germany. According to government statistics the overall population of approximately 82.3 million in Germany is predicted to decline over coming decades, while the country's population of those aged 67 and older is predicted to rise from 15.1 million in 2013 to 21.5 million by 2040, or 42%.

A group of South Dakota seniors inadvertently ate a batch of marijuana brownies during a card game last Tuesday, and had to call police for assistance, per the New York Post.

A 73-year-old woman brought the brownies, but did not know that her adult son had baked them with THC butter. Police responded to multiple calls of a "possible poisoning" and found the seniors were "under the influence" while playing cards at Tabor Community Center.

Michael Koranda, 46, was arrested and charged with possession of a controlled drug or substance.

He reportedly told authorities that he cooked the brownies with a half pound of THC butter that he purchased legally in the recreational state of Colorado.

Koranda had gone to bed when “his mother unknowingly took the brownies to the card game where several people ate them,” according to an affidavit obtained by The Smoking Gun.

His felony charge is punishable up to 5 years in prison with a $10,000 fine, according to the report.

"An investigation into the incident lead me to believe that the patients were all under the influence of THC from a batch of brownies that were brought to the Community Center by Irene Koranda," Deputy Sheriff Joel Neuman said.

Irene Koranda “willingly gave [the sheriff] the remainder of the brownies in a plastic container," Neuman reported.

There was no report of any injuries caused by the incident.

South Dakota residents voted to approve an amendment to legalize recreational marijuana in November, but the referendum was struck down by the state’s high court.
