The Globe and Mail reports in its Tuesday, Oct. 30, edition that Canada's recreational-weed sector has strict rules that limit companies' ability to use advertising to build their brands. The Globe's Susan Krashinsky Robertson writes that on Tuesday, the Canadian Marketing Association will release a guide designed to address questions about the proper interpretation of those rules. The Cannabis Act's prohibitions include: TV and radio advertising; naming a sports or cultural facility; promoting a brand through sponsorship; advertising the price of a product other than at the point of sale; testimonials or endorsements; evoking emotional associations or linking the product to a "way of life," such as suggestions of glamour or excitement, or through sports marketing; using promotional characters; and appealing to people under the legal age of consumption -- which varies from province to province. The number of rules present a challenge for cannabis producers and retailers that want to build brands with consumers. Exactly what the legislation allows them to do "isn't completely clear in some areas," says CMA vice-president of public affair Sara Clodman. "We are providing as much guidance as we can."
