Via Starjewel (who put a more positive spin on it than me), Ottowa study shows light marijuana use doesn't have negative IQ effects:
Interpretation: Current marijuana use had a negative effect on global IQ score only in subjects who smoked 5 or more joints per week. A negative effect was not observed among subjects who had previously been heavy users but were no longer using the substance. We conclude that marijuana does not have a long-term negative impact on global intelligence.
