Realistically, whats the chance you can get a statistically significant result in the very hostile environment that surrounds cannabis use from such a very broad study?<p>They couldn't closely control the purity, variety or frequency of cannabis use. They obviously can't control for social stigma.<p>I guess this is just my general displeasure at articles fishing for correlations in a sea of bad data, longing for that resolving barrier of "statistical significance".

This definitely echoes my own observations. Due to various circumstances, in my life I have so far been thoroughly exposed to numerous, unconnected groups of drug users – all of which were smoking weed more or less regularly, and almost all of which were losers. I am very happy to find out about this study, and I hope it receives an adequate exposure.

Let's see who funded the study: (* added for emphasis) "This research received support from UK Medical Research Council Grants G0100527 and MR/K00381X/1, US National Institute on Aging Grant AG032282, US National Institute of Mental Health Grant MH077874, and <i>US National Institute on Drug Abuse</i><i></i><i></i><i></i><i></i>* Grant P30 DA023026. Additional support was provided by the Jacobs Foundation."<p>I agree adolescents probably shouldn't partake, but for adults, there's far worse things.

The content is behind a pay wall

can anyone name one figure who had an important contribution to mankind, and smoked weed?

So wait, let me get this straight. Using cannabis irregularly means that I will lose about one IQ point by the time I hit middle age? If there was ever a reason to smoke up!
