The stigma of Cannabis comes from the hippie era during the 60's and 70's. It gave a very liberal, careless thinking about cannabis.
But if you look at other cultures such as ours, we were more conservative when it came to cannabis. We consumed it in a liquid form-just like the majority of Asian countries. We used it for wounds and cuts during battles, for chronic pain, joint pain and even digestion (the CBD found in cannabis helped with this). However, the THC content is what one should be weary of since it can alter the mind. When it's necessary, moderation is the key.
It recently became fully legalized here in Canada in 2018. There will be extensive research that will go into this plant in the near future. Interesting stuff.
Lot's history associated with this plant.
