Well, since you're on a very specific forum, i would 'suggest' you read some "appropriate"! Two great newer works (2012) to enlighten anyone about Cannabis;
"Blowing Smoke" by Dr. Michael J. Reznicek, a Washington State Psychiatrist, who writes about the "broken" Model of Addict and Toxin.
and; from Colorado and by Greg Campbell who also wrote; Blood Diamonds and Flawless; "Pot,Inc."
