When my Father was still alive he smoked it sometimes to help with some pain from cancer. I never saw him high, nor did I know he smoked it. My brother told me years later. I saw him a lot of pain, if it helped ease the pain I'm glad he smoked it.
I use to smoke weed but haven't in years. I won't again but I can't say I hated it. Also Hemp is used for many other things, clothing, rope , it has many other uses.
