ok good points...but you must admit your not going to defend your PhD dissertation stoned or logically entertain seriously complex issues stoned. Im familiar with smoking and also with cogent thinking. Stonedness certainly does not lend itself to rigorous disciplined thought.
I think that partially explains much of the baseless dogma that fills stoner forums.
Rigorous, disciplined thought is just that- a discipline, requiring practice to achieve and maintain.
At the other end of that scale of thought processes lives free form, unrestricted brainstorming.
In my humble opinion, Genius lies in being able to do both- or at least go back and forth- constructively.
Cannabis certainly helps me do this. Therefore, I believe it assists my cognitive process... and I'm not alone in this thinking. No one could reasonably accuse the late Dr. Carl Sagan of an inability to think critically- yet he was an early and vocal advocate for legalization, based on his own experience.
Not a bad refutation, eh? Especially considering I've been rippin' hard on my hash pen all morning?!
