Snacks containing marijuana were brought into an elementary school in Oshawa on two separate occasions in the past two weeks, the Durham police and the Durham District School Board said Tuesday.

In the first incident, which occurred during the week of May 7, four students in Grades 7 and 8 reported feeling dizzy after eating gummy bears brought to school by a student. The candies were found to be infused with THC, the board and police said in news releases issued Tuesday afternoon.

It wasn’t clear how the student got the gummy bears, which were prepackaged and not made at home.

In the second incident, a Grade 6 student brought in homemade cookies as a treat for their class. After eating the cookies, four students — three age 11 and one age 12 — reported feeling dizzy.

“An investigation revealed that one parent had made the cookies for a spouse with a medical marijuana license. Some of the batch had been taken from the home without consent by an older sibling (high school age), but somehow ended up in the Grade 6’s backpack,” Durham police said.

The news releases did not identify the school, or say if either of the incidents resulted in criminal charges.
