Let's look at a chart of marijuana "Past Month" use so you know exactly where I'm coming from:
First of all, marijuana use fell 65% in the period from 1979 to 1993. It then remained relatively flat for 8 years. It is up slightly (NOT explosively) in the last few years.
Why is it up? My guess is that the increased calls for medical marijuana and decriminalization have a lot to do with it, just as it did in Jimmy Carter's days.
Why pick 1993? The vast majority of the fall had already occured by 1989, when Dr. William J. Bennett became the first cabinet level drug czar.
"My office is already conducting an exhaustive review of our national fight against drugs on both supply and demand sides." --Dr.Bennett, March 1989.
Did the WOD succeed in curbing supply or demand over the last 15 years?
