My friend’s aunts from Qingdao were totally open to using CBD for pain relief. Since CBD doesn’t make you high like THC, I can see hemp being legalized, especially since hemp also has historical usage in TCM. Marijuana, though, I think won’t happen for a long while since seeing and treating the effects of opium addiction is in living memory. Some other friends who went to Tibet a few times did mention that there are some hookah cafes where there’s something other than tobacco in them
