A high school teacher downstate at Roxana Senior High apologized for making references to drugs in his math class.
He asked students how high they would be three hours after using cocaine and how much they would owe a dealer for a $1,000 payment paid at only 25 percent a day for a year.
Teachers and students were shocked.
The school says he has apologized to students and said his intent was never to promote or make light of illicit drug use.
