The Canadian Vaping Association (CVA) commends the Nova Scotian entrepreneurs who have submitted intent for a constitutional challenge after Nova Scotia passed restrictive vapour product legislation. The new legislation imposes nicotine ceilings and bans flavoured vapour products. Flavoured products are the key for adult adoption and are used by 90% of adult vapers. Eliminating flavours will discourage adult smokers from transitioning and cause many vapers to return to smoking.
