Wish I could tell you. They didn’t do it with pot either despite it having plenty of medicinal applications. Maybe they perceive it as more of a threat than a money making opportunity? It’s less addictive than other opiates (from what I understand) and we know that addiction was part of their business model with opiates . It helps people recover from addiction in a way that doesn’t require life-long treatment so maybe it would be a net-negative in their eyes. Idk I just woke up and I’m rambling lol
