Regular pot smokers have shrunken brains, study says - LA Times

Experimental mice have been telling us this for years, but pot-smoking humans didn't want to believe it could happen to them: Compared with a person who never smoked marijuana, someone who uses marijuana regularly has, on average, less gray matter in his orbital frontal cortex, a region that is a key node in the brain's reward, motivation, decision-making and addictive behaviors network.

More ambiguously, in regular pot smokers, that region is better connected than it is in non-users: the flow of signal traffic is speedier to other parts of that motivation and decision-making network, including across the superhighway of "white matter" that connects the brain's hemispheres.
...
Researchers noted that the IQ of the marijuana-using group was significantly lower than that of the non-using group--not a finding of the study, but an incidental factor that might be indirectly linked to marijuana use.

Right wing propaganda, who sponsored this study? Westboro?

Maybe they had less gray matter to start with.

That's what I was wondering.

Those with less grey matter are naturally inclined to become pot smokers.

damn that sucks. guess I'll have to put this out

Lol, okay.

 

[golfballs]

Lol, okay.

Yeah, I guess the two aren't mutually exclusive.

Look at the brain on that guy!

2nd paragraph is a negative?

not much grey matter IMO

I knew that a number of you on here just had to have something medically wrong with you.

Thanks for the link. Explains a lot.

Lawgator already has a shrunken brainlol:

The article answers these questions:

Even now, however, the authors of the study acknowledge that they cannot discern whether a pot smoker's smaller orbital frontal cortex is the cause or the result of chronic marijuana use. A 2012 study found that subjects with a smaller orbital frontal cortex at age 12 were more likely to start using marijuana by age 16, suggesting that deficits in this crucial region may predispose one to substance-abuse behaviors.

Marijuana can't be anymore harmful than tobacco.

Does the 2nd paragraph not basically say that they showed faster and more efficient access to other parts of the brain, including white matter referred to as a superhighway?

Or translate it for me if I'm missing something.

How many of you smoke, or once smoked pot?

I never did but i was with folks who did. With all that pot smoke it was about like smoking it yourself.

Weed is bad. Have we not been told that enough to believe it by now?

A v4 is more efficient than a v8, but it's less powerful.

They left out denial

I can't recall if I ever smoked weed. In my best Ollie North voice, of course...

Faster to get hungry. Faster to get back to 7-11 for blunt wraps.
