One year after the legalization of cannabis, Alberta retailers and producers are gearing up for the introduction of edibles to the market but aren't sure what to expect.   "The regulations aren't very understood for us right now," said Jayne Kent, who co-owns a Spiritleaf cannabis store in St. Albert.   "We welcome the opportunity to get that literature to see what the products are and understand how they're going to work for consumers."   Health Canada has released its rules surrounding potency, packaging and marketing of edibles, but retailers haven't seen the final products.   "It's a bit of a grey area," said Micheal LeBlanc, manager of a Canna Cabana store on Parsons Road in Edmonton.   "The agency has regulations around flavouring and enticing children, so I'm still curious about how they're going to roll out products like gummy bears or flavoured cookies."   While edibles will technically become legal on Oct. 17, they won't be available for purchase until mid-December, since licensed producers have to submit their products to Health Canada for a 60-day review.   Despite the uncertainty, Aurora, an Edmonton based cannabis producer, has been investing in edibles for the last year.   "We are extremely well-prepared for legalization 2.0," said Aurora chief corporate officer Cam Battley.   The company is rolling out a diverse line of edibles, Battley said, ranging from vaping products to cannabis-infused beverages.   "We are anticipating significant interest among adult consumers in the new product forms. It's a novelty."   'Pioneering an industry'   Edible products could translate into $2.7 billion worth of sales in the next year, according to Deloitte's June report on the country's cannabis industry.   LeBlanc hopes the launch of edibles will be smoother than the introduction of legal cannabis in October 2018, which led to stock shortages and delayed licences for retailers.   "It's a bit of a wild west," he said. "I know we're pioneering an industry, so hopefully it gets rolled out pretty well."   Customers are excited, Kent said, and have been asking for more information.   "People are curious, they really want to see what's coming."   Regardless of the format edibles will take, providing accurate information to consumers will be crucial, she said.   "It is a different way to consume cannabis and we need to be responsible about that," said Kent.   Users should start with a small dose, LeBlanc said, and be aware of how cannabis can interact with other intoxicants, like alcohol.   "We make sure to pass that information along to the customers and always tell them 'start low and go slow.' "   Industry tackles waste   Health Canada's strict rules are meant to keep cannabis out of the hands of children, but have also had unintended consequences.   The fledgling industry is grappling with the waste it generates through packaging, which must be child-proof and tamper-evident.   It has motivated at least two companies, Canopy Growth and High Tide, to create their own recycling system, in partnership with recycling company TerraCycle.   High Tide installed receptacles in its 25 Canna Cabana stores to collect empty packages, said chief operating officer Alex Mackay.
