Hey, then why is there still a demand for illegal pot. Including states where pot is legal.
Because it's only been legal for a few years, and some states are overtaxing and overregulating - as has not happened with the addictive mind-altering drug alcohol.
I doubt that a user/buyer is concerned about well regulated.
Of course they are - those who drank bathtub gin during Prohibition switched to legal booze when Prohibition was wisely ended.
This is where legal pot wins if you call it a win.
The whole process of growing and processing are getting so refined that there are massive amounts of THC.
And this is all very new because never before did pot have 40% THC and so there is very little information about the affects of massive amounts of THC on the human body (brain, liver, kidneys, etc. organs).
More health information should be available in the near future and I predict that it will not be good. Too much of anything is not good. Heck, drinking 100% alcohol is not good for you.
If I were a grower or a producer I'd be prepared for the day when there are massive class action litigation against all entities involved. It will happen; guaranteed.
