Hippie!
This allows my neighbor with MS to treat her debilitating pain without getting "stoned".
There are analgesic components in pot that are completely separate from the components that get a person stoned. These components vaporize at under 300 degrees; the psychoactive components come out at OVER 300 degress.
It is a lot more complex than that, but I am heartened that there is now study in this area. To see my neihbor suffer makes me sad. It takes her a good 5 minutes just to get into her car ever day.
