The pot we smoked in the 70s and 80s is nowhere near as potent as it is today. People are finding out the hard way that there are toxic levels of THC.
there is a way to get around the weed law for THC
i have no idea how it compares but Delta-9 thc is legal because of a Farm Bill
I have considered trying edibles to see how it effects pain but then decided there is no regulation and I might get bunch of pesticides
I'm out of the loop these days, but I remember in the 70s and 80s it was plenty strong enough to do what people wanted it to do. Didn't seem to need much improvement.
As you say, it's much stronger now, and I don't see the reason for this. It's like alcohol prohibition in the 1920s -- no beer, no wine, no gin. Then the country changed their mind and said alcohol could be legal -- but they didn't suddenly ONLY sell 200 proof Everclear grain alcohol. There was no need to go as hard as humanly possible in 1933. But for some reason, we legalized cannabis (in some states) and now it's 200 times as strong as it used to be. That's just weird.
