A Barrie boy turned up his nose at a cheese sandwich Feb. 28 when he noticed it was sprinkled with marijuana, police say.

When his Grade 2 teacher asked why he wasn’t eating his lunch, the boy said his sandwich had “weed from his Dad’s smokes.”

When Barrie officers arrived to inspect the lunch, they found marijuana residue in the sandwich.

It turns out the boy's father, who has a medical marijuana licence, made the sandwich on the same kitchen counter he used to prepare his prescription.
