- Fuzzwah 14y agoWelcome to the wonderful world of publicly funded science publication!

- xk_id 14y agoThis 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.
- psweber 14y agoSounds like you've never met a graphic designer.
- Chaotic 14y agoOr a programmer.
- bsenftner 14y agoor a successful entrepreneur
- paulhauggis 14y agoBut you don't know how much more successful they could be without smoking pot regularly.
- xk_id 14y agothanks, I didn't want to say it myself :)
- thracky 14y agoYou probably have met more pot smokers than you realize. Not everyone goes around advertising it.
- revelation 14y agoRealistically, 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? They couldn't closely control the purity, variety or frequency of cannabis use. They obviously can't control for social stigma. 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".
- gillett 14y agoNormally I would agree with you, but the controls you are calling for are unrealistic. While I'm no expert in the field, this is clearly not the first study to suggest long-term cognitive decline in adolescent-onset users, and any evidence that can support previous findings, albeit very small, is important to consider. I think the authors are correct in stating that there is a popular and naive belief among adolescents that cannabis is safe - especially in moderation - and the evidence to date does nothing but refute that. Hell, in this study they found a statistically significant IQ drop (over the course of 20 years) for adolescent-onset users that only smoked 14 days out of the year on average (the median, to be precise). Even if they do put forth incomplete or questionable conclusions, teens should be exposed to more of these findings and be allowed to think for themselves. They certainly should not have to endure the inane public service announcements that merely reinforce the belief that marijuana is not actually "that bad."
- andreasvc 14y agoThere is an even more popular and naive belief that drinking alcohol is safe. With the current social conventions and legislation the consumption of this solvent is pervasive and deemed acceptable, while other drugs which are objectively less harmful are criminalized ferociously. It has to be said that all this is a rather arbitrary state of affairs.
- thracky 14y agoLet'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 US National Institute on Drug Abuse* Grant P30 DA023026. Additional support was provided by the Jacobs Foundation." I agree adolescents probably shouldn't partake, but for adults, there's far worse things.
- Chaotic 14y agoSo 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!
- njs12345 14y ago6 IQ points is a bigger deal, but for any of the other groups, the effects are certainly fairly minor..
- xk_id 14y agocan anyone name one figure who had an important contribution to mankind, and smoked weed?
