There is no major limiting factor restricting health insurers and banks like the issue of regulation around cannabis. Despite the fact that more states are legalizing the medical and recreational use of cannabis, it is still regarded as illegal on a federal level. Cannabis is classified as a Schedule I narcotic drug which means it is of no medicinal use and has a very high degree of dependence. Though many will agree to the fact that this designation of cannabis is not right, it is still the current state of things. Many insurance providers will not want to be at loggerheads with the federal government which is why they have held back majorly until regulation changes.
