abilty to focus, memory ect. is effected for days after I smoke.. but I only smoke once in a blue moon and when I do I smoke atleast Quarter ounce of cally weed. (300 bucks?). That may be why... you left out knife hits... the best way to smoke really good weed. But I digress, this is neither the time nor the place for a discussion of drugs. Lets keep it on topic
