An Illinois high school teacher sparked outrage with a homework assignment in which he used drug references in his math equations.

Local station KTVI-TV reported that parents and teachers alike were shocked and outraged by the questions, which included such gems as:

— Brooklyn high school debate team wins national championship with ‘Why Black Lives Matter’ speech — 

“You take six hundred milligrams of cocaine, your body filters out forty percent per hour, how high are you in three hours?”

“Unfortunately, you can’t pay your dealer and she sets up a payment, you owe her $1,000 and 25-percent daily, how much do you owe her one year later?”

— ‘I don’t believe the victim’: Female judge reprimanded for shaming jurors who convicted rapist — 

The parents were shocked to see these references in their kids’ homework. And as one parent pointed out, the questions could have been written differently without changing the answers or the methods the students were learning to solve the equations.

“I think they could have used something else, maybe cans of soda, bottles of water, fruit, something you can put weights to, no cocaine or drugs, that’s not very good,” said Christina Metz, one of the parents outraged by the questions.

What’re more, many members of the community see the questions as trying to make drug use seem more acceptable.

The school district responds

The principal tried to play off the questions as something that the teacher came up with in class on the fly, but the school district’s response was much stronger.

The Roxana School District released a statement that reads, in part: “The district is addressing the matter with the faculty member and those impacted by this incident. The faculty member has apologized to students and parents for this lapse in judgment and has reiterated the intent was never to promote or make light of illicit drug use.”

Now, the district is investigating the teacher to determine whether or not he violated district policy with the questions.
