The Coca-Cola Company said Monday it is “closely watching” the expanding use of a cannabis element in drinks, another sign cannabis and cannabis-infused products are getting more acceptance in mainstream culture and a harder look from long-established pillars of American business. The statement came after reports the beverage giant was in talks with a Canadian cannabis company to create a health drink infused with cannabidiol, a naturally occurring non-psychoactive compound derived from the cannabis plant. Shares of the company, Aurora Cannabis Inc., closed up nearly 17 percent on the Toronto Stock Exchange after the report.
