Attempting to reconcile these contradiction, a credible case can be made that marijuana should remain generally illegal, but with a clear and accessible exemption for bona fide medical uses. That is now where American public policy is settling, with a messy compromise in service of conflicting facts.
As for the video that you posted about the "carnivore diet." it is consistent with my experience. Eventually, I figured out that the primary reason why an all protein diet benefitted me was because I have celiac disease. Doctors doubted it, but medical tests proved it definitively.
Congrats on your healing. I’ve been only eating meat & drinking water for 1425 days with zero downside experienced. I’ve been 100% symptom free for over 3.5 years & every day continues to be better than the day before.
Regarding Cannabis: A) it should be up to states to decide whether it is legal to have & use or not & B) It is not for everyone C) everyone who uses cannabis is not a bum or a loser in life.
