Cannabis Smoking 'Permanently Lowers IQ'

"...“persistent users” who started as teenagers suffered a drop of eight IQ points at the age of 38, compared to when they were 13."

    Oh, for cryin' out loud, this test is flawed!! Everyone knows that 13-year-olds know EVERYTHING, so it's bound to be downhill from there.

And now I know why I no longer know everything. ;) The "study" is flawed for a whole host of other reasons. For one thing, it's a statistical study done over the course of 40 years with a tiny (1000) sample group from an obscure location(Dunedin, New Zealand.) The article does not provide much more statistical data-such as an R2 or even SD-so that the strength of the correlation(s) can be determined-so one would need to get access to the journal(which is not devoted to psychiatry, biology, medicine, or pharmacology, but is instead 'multi-disciplinary'-another red flag)that it was published in.

I had attached a caption to this originally that read something like, "They've studied it, mmmKay? Stop whining when they shoot your dog." that was somehow lost in translation...

I really wish the media would stop confusing very limited statistical fishing expeditions designed to bolster a political point like this with actual science-they won't, but it would be nice.

I wish I had known this when I was a teen. . . I feel so stupid going into the world with an IQ of only 143 - I'm now amazed that I was able to get through Jr High and High School without taking the short bus every day.

Better be careful, Sam. If evidence can be produced to show that you call yourself a "citizen of the United States", (a.k.a. a 14th Amendment citizen), in order to get benefits/privileges, your parent (parens patriae) may not allow you to smoke marijuana.

Bein' "allowed" to blow a reefer would spoil half the high of it. Sam
