CBD, one of the more than 100 chemicals in cannabis, is emerging as a popular wellness ingredient. The plant extract, often consumed as an oil under the tongue, is now the featured ingredient in high-end products including coconut oil, body lotion, face serum, olive oil, jam, bath scrub, cold-brew coffee, sports salve, lip balm, infused water, gummy snacks and dog treats. Products' prices vary but may cost about triple what their CBD-less counterparts do.
