The most common delivery format for cannabis, the flower—smoked as buds or as cigarettes—accounts for nearly 40% of retail sales, according to a press release. Vaporizer cartridges with concentrated THC or CBD compounds takes the second largest share, but it’s falling, as concerns about vaping-related lung illnesses rise. Edibles and topicals are predicted to rise, and to rise quickly, as they stand to benefit the most from legalization of hemp-based CBD; major retailers are already offering CBD-infused food and beverages, as well as CBD-infused cosmetics.
