Nova Scotia has announced a ban on flavoured e-cigarettes, while Ontario continues to mull the idea of doing the same. The move by the Nova Scotian government follows a nationwide clampdown on vaping. A 2016-17 survey suggested 37 per cent of Nova Scotia students in grades 7 to 12 had tried vaping at least once — one of the highest rates in Canada. Ontario has already said it would ban the promotion of vaping products in convenience stores and gas stations beginning next month. Ontario's health minister also said her province is also considering a ban on flavoured vaping products. New restrictions on vaping were recently adopted in Prince Edward Island, British Columbia and Newfoundland and Labrador. The P.E.I. government passed legislation that raised the legal age to buy tobacco and e-cigarettes from 19 to 21. The legislation also banned certain flavours of e-cigarettes and restricts where the products can be sold. In British Columbia, a 10-point plan is aimed at protecting youth from the health risks of vaping. Newfoundland and Labrador banned the introduction of cannabis vape products when pot consumables go on sale later this month. In the United States, 47 deaths have been attributed to vaping, and 2,000 cases of severe lung disease have been reported. Thirteen cases of vaping-associated lung illness have been reported in Canada as of Dec. 3. So far there have been no deaths.
