​A farmer in France has been given a one-month suspended jail sentence for feeding cannabis to his 150 ducks.

Michel Rouyer was arrested after police found 12 cannabis plants and 11 pounds of marijuana during a search of his home in the village of Gripperie-Saint-Symphorien, reports Metro.co.uk

“There’s no better worming substance for them; a specialist advised me to do it,” the farmer said.

His lawyer, Jean Piot, added, “This is for real; not one [duck]has worms and they’re all in excellent health.”

But authorities thought he was a quack.

“We have never investigated a case like this,” police said. Rouyer was given a one-month suspended jail sentence and fined 500 euros (about $700).

The farmer did admit smoking “some of it” by himself. But still, it was mostly for the ducks, he said, reports Lesley Ciarula Taylor at TheStar.com
