This conversation is confusing without the FDA isn’t everything allowed by default and you get far worse like the current supplement industry?
FDA and DEA should be concerned mainly with the contents matching the box, and not on medical claims of effectiveness.
Regulatory challenge is that the FDA have to combine 3 related but seperate concepts:
1. Manufacturing quality/ingredients accuracy (is the product what is says on the tin) 2. Safety 3. Efficacy
Medicines must pass all three, supplements don't have to meet any.
