Study Shows Marijuana Use In Teens Correlates To Decreasing IQ
retroworks writes "The BBC reports on a paper published in the U.S.'s Proceedings of the National Academy of Sciences showing a correlation between persistent, regular cannabis use and risk of lower IQ. The study finds the risk particularly correlates use of cannabis by teenagers who use the drug "four times a week year after year." The more people smoked, the greater the loss in IQ. Reviewers of the study at King's College Institute of Psychiatry states that the data and methodology are exceptional, but she also cautions that there may be another explanation, such as depression, which could lower IQ while stimulating marijuana use. The study does not mention or rule out 'nocebo' effects, i.e. just feeling stupid for spending your teens hanging out with potheads."
Yeah, well, that's just, like, your opinion, man.
It affects reading comprehension also....
Propaganda by whom, and for what purpose? How do you identify it as propaganda instead of legitimate science? You have to answer these basic questions and support your answers with evidence before anybody is going to buy into your conspiracy theories.
Propaganda; n. Any material which proposes to sway a reader to form a conclusion that conflicts with your own.
Perhaps it's just that low IQ is correlated with answering "yes" on a marijuana survey.
