The Bears misunderstanding is of the word 'treatment', treatment doesn't only include FDA based medications, treatment is basically ANYTHING that can help improve the effects of the condition. (Example, in medical missions, ive used bananas as part of a treatment plan for severe dehydration for people who cant afford, physical activity is a very common treatment).
Treatment and cure, those words are not the same.
CBD imo has shown in some unofficial studies shown to be an alternative treatment for certain conditions. Cannot be considered a 'cure' at this point, for myself I wont say that CBD a cure for anything, but I dont have anything against researchers saying its a potential cure cause there are thousands of 'potential cure' being researched and studied at thistime, thats the whole point of research finding the potential.
As a treatment, nothing wrong with using MMj as a treatment(or ANYTHING) as long as the side effects dont cause anymore harm or complications, it really depends on each and every patient's case and thats up to the MD, patient and state laws
