Marijuana affects the index iq.
A experimental interpretation challenges previous research that suggested teens put their long-term brainpower in threat when they smoke marijuana heavily. Instead, the examination indicated that the earlier findings could have been thrown off by another part - the effect of poverty on IQ. The author of the original analysis, Ole Rogeberg, cautioned that his theory may not hold much water 4rxday com. "Or, it may upo a concern out that it explains a lot," said Rogeberg, a enquiry economist at the Ragnar Frisch Center for Economic Research in Oslo, Norway.

The authors of the primary study responded to a ask for for comment with a joint statement saying they stand by their findings. "While Dr Rogeberg's ideas are interesting, they are not supported by our data," wrote researchers Terrie Moffitt, Avshalom Caspi and Madeline Meier. Moffitt and Caspi are make-up professors at Duke University, while Meier is a postdoctoral comrade there.

Their study, published in August in the Proceedings of the National Academy of Sciences, attracted media acclaim because it suggested that smoking pot-belly has more than short-term chattels on how race think. Based on an dissection of mental tests given to more than 1000 New Zealanders when they were 13 and 38, the Duke researchers found that those who heavily cast-off marijuana as teens irreparable an average of eight IQ points over that tempo period.

It didn't seem to matter if the teens later omission back on smoking pot or stopped using it entirely. In the curt term, people who use marijuana have memory problems and unpleasantness focusing, research has shown. So, why wouldn't users have problems for years?
