A British mother has vowed to return to Canada to get more cannabis oil used to treat her son’s severe epilepsy after having a supply confiscated at Heathrow Airport.

Charlotte Caldwell made the trip to Toronto and back with 12-year-old Billy to get a six-month supply to treat up to 100 seizures a day, but said border officials seized the oil on Monday.
