Regular pot smokers have shrunken brains, study says
MSN ^ | 11/11/14 | Melissa Healy

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.

The researchers who conducted the study speculate that the orbital frontal cortex's greater level of "connectedness" — which is especially pronounced in people who started smoking pot early in life — may be the brain's way of compensating for the region's underperforming gray matter. Whether these "complex neuroadaptive processes" reverse themselves when marijuana use stops is an important unanswered question, they added.

Just so we understand the stakes, we’re all in agreement: If something is bad for you, you should be put in jail for using it, correct?

This could explain why RATS win elections.

I don't know. In 2014, both pot and the GOP routed the opposition. Legalization went 3 for 3.

So when will the anti smoking pot commercials be seen on tv, like the ones they do for the horrors of cigarette smoking?.

Considering that most pot smokers are liberals to begin with, that doesn’t leave much room for “shrinkage”.

Lets change the title:
“Pot smokers have better connected, speedier networks across the brain’s superhighways.”

They've been airing for the last 30 years. Maybe you missed them.

That is indeed one of the conclusions of the study. Of course, I don't think the OP has that in mind.

It won the majority (58%), but 60% is needed for a constitutional amendment in Florida.

I’ve only seen the ones for smoking cigarettes, not pot. Wow, I guess I did miss them.

"I notice they seem to be herd animals as well".

I vape Cannabis every single day and consider myself an independant thinker. Also,

I pay my bills.

I show up to work every day clean and sober.

I maintain a high paying job, and I do not suck at it, according to my boss(es).

I try hard to be a good parent.

I try hard to live conservative values and not just spout them.

A am opposed to drug legalization because it undermines the moral foundations of our culture, and sends the wrong message to kids.

I try to be a good neighbor.

I do not leave my property when under the influence.

You would never guess I was a pot head by talking to me; I am fully integrated into society. What else is it that you people want?

But yeah, some days I really feel like my brain has shrunk, so I agree with this article.

And Al Gore won the popular vote. He still lost.

It’s sad hearing people justify and try to make their addictions seem ‘normal’.
