A woman with a nervous cow will soon be headed to jail after police found the Polish lady growing marijuana.

A woman in Lobez was arrested and charged with cultivating a narcotic after Polish police found she had been growing the drug to calm her "skittish and unruly" cow.

According to the PAP news agency, the cow was so wild it broke someone's arm, yet after a suggestion that the 55-year-old woman should mix the drug in with the cow's feed, the animal has been "as calm as a lamb."

Reuters says the woman's plants, grown from seeds she bought at a market, reached nearly three meters tall and were extremely potent. Yet, police maintain that marijuana possession is a crime throughout Poland. The woman faces up to three years in jail if convicted.
