There are exceptions. My brother and sister-in-law have been smoking the stuff for over 50 years and they seem to function just fine, in fact, last summer he showed me his garden where he had a few plants growing. Quite well, as a matter of fact.
I haven’t smoked the stuff in over 40 years, for a lot of reasons. I didn’t like how it affected me mentally, the cost, among others.
I also know that it didn’t seem to help them much when they had COVID.
Gave me the munchies.
Growing it is pretty easy. Insect free, deer hate it. You can just stick it in the ground if you don’t want an elaborate indoor operation. You have to monitor it for bud rot outdoors.
Smoking it is VERY unhealthy
