FYI. The size of the difference between potheads and non-potheads is extremely tiny. Basically, of all the between person variance in cognitive function, barley over 1% of that variance was tied to whether or not you were a pothead. IOW, if you guessed which of 2 people had higher IQ from their pot use, you would only be correct 51% of the time, and random chance is 50% correct.
