We have done what humans do with their quest for maximizing everything and have twisted the plant so that the THC is out of balance with the rest of the cananbinoids in the plant. I'm no doctor, but from what I've read and listened to in seminars, the plants with a better balance is much better for medicinal use.
The quiet part people don't want to be said out loud is that the medical play was just to get the ball rolling towards legalization. Now that it is in several states, we're doing to marijuana what we did to IPAs and microbrews. Do everything you can to maximize disregarding the overall effect unless that desired effect is just getting wasted.
