Much of the legislation on kratom is also complicated by the exact wording of the bills themselves. Some are only written to ban Mitragynine and 7-hydroxymitragynine, the two main alkaloids in kratom, and this causes legal confusion over wether whole leaf ground kratom should be considered illegal or not. Many see bans such as those as only pertaining to the isolated alkaloids and not the raw plant form.
