NORTH VANCOUVER, B.C. - Students in North Vancouver are being warned by police that eating sweets containing marijuana could give them far more than the munchies.

RCMP Cpl. Richard De Jong says two Grade 10 students were dizzy, had heart palpitations and vomited, and one of them had to be taken to hospital after eating dessert squares that contained pot.

De Jong says police believe the Krispy squares and brownies were bought at a 4-20 event, an annual celebration of cannabis culture held on April 20.

He says students the then sold the squares at their schools and that police are continuing to investigate the details.

Mounties issued a photo of the brownies wrapped in foil and the Krispy squares wrapped in plastic affixed with a label listing the ingredients of cereal, marshmallow, vanilla and canna butter, which is made by boiling butter and marijuana.

De Jong says people need to beware that they have no idea how such food was made or how their body will react to it.
