I admittedly have never heard of Kratom.......had to look it up. It looks really interesting and definitely something I need to know more about. I live in chronic pain and am sensitive to opiates so am always looking for alternatives. I too had thought of a drop or two of CBD oil behind a cavy's ear, much as we administer Ivermectin.
The way the medical marijuana system works in CT is that one must obtain a verified diagnosis (from a mental health professional) that is on a list of conditions for which MM can be approved. That individual then takes the paperwork to a physician who then interviews/screens them for a MM card. They pay that physician a consultation fee ($300) plus $100 for the card which must be renewed after a year.
I have an MD friend who is one of about a half-dozen such physicians in the state so I have a unique perspective and a pipeline of information from which to draw. My husband and BIL both suffer from chronic, severe pain and use MM. I find it pretty amazing at just how sophisticated the formulations are and getting better all the time. However, until they come up with one that has no psychotropic effect, I won't be using it.
As a person who practices Chinese Medicine, I am accustomed to using herbs and other natural remedies whenever possible. I've seen too many nasty side effects from using multiple pharmaceuticals.
