Cecil’s numbers in his April 20 ,2012 column are probably pretty good and if they aren’t, well they are probably as good as any others.
The average quality of pot has definitely increased over the years along with the price of it.
But the increase in potency comes with a trade off that he failed to mention.
Pot smokers smoke enough to get high and put their pipe or hand rolled away for an hour or maybe even two or three hours and then take another toke or two or however many they want to restore their high.
Just one puff of really good pot is enough to last for a long time whereas a ditch weed stogie is barely enough to feel it.
If you want to get drunk on beer your drink a maybe a half a gallon. A quart of wine will make you just as happy and only five or six shots of hundred proof whiskey will do the job equally well.
Pot smokers who have the good stuff just don’t smoke very much of it at any given time and so the potency of it most likely doesn’t matter very much from any point of view.
