SPRINGBORO, Ohio -- An Ohio elementary school teacher faces charges she let her 15-year-old son sell LSD (Lysergic acid diethylamide), also known as acid, and allowed teenagers to use it in her home.

Forty-year-old Amy Panzeca, of Springboro, pleaded not guilty Tuesday, August 15, in Warren County to charges including permitting drug abuse and endangering children. She was freed on bond.

Prosecutors say Panzeca's son sold LSD to at least 20 high school students. He faces felony drug charges and is being held in a juvenile detention center.

A drug task force found LSD and marijuana during a search of the family's home in May.

Panzeca teaches fifth grade. The Springboro school district has placed her on paid leave.

Panzeca's attorney couldn't immediately be reached for comment. (AP)
