Marijuana Causes Poor Memory and Alters Brain Structure

Ian-Fortey by Ian-Fortey on Dec. 17, 2013

According to a new study, teens who smoked marijuana daily for three years ended up doing extremely poorly on memory tests and also have signs of abnormal brain structure.  What’s abnormal brain structure?  They look similar to the abnormalities you’ll see in a schizophrenic and the parts of the brain that deal with memory seem to shrink and collapse.  So not cool, man.  The younger you start smoking weed the more abnormal your brain gets.



Even more noteworthy is that your brain displays these same abnormal structures as long as two years after using marijuana use, so it could very well be long term or permanent alteration.

Plus, get this, there’s this new study that says people who smoke marijuana daily for three years do really poorly on memory tests and also it gives them abnormal brain structure.  Your brian ends up looking weirder the younger you start smoking, too. And it doesn’t go away, either.  Like two years after your stop smoking, your brain will still be all shrinky and weird.



Oh, and dude,I was outback with the janitor earlier and he was all “Dude, so these scientists grabbed a bunch of kids, right?  And they made them smoke pot in this cage, right?  And like, after three years they dissected their brains, right?  And their brains were so small and the kids couldn’t even remember stuff so they sent them home, but then two years later they came back and their brains were still small, man!”  It’s the NSA, I think.  You gotta watch your back, man.

Anyway, my mom tried telling me that smoking up makes you forget shit, but what does she know?  I was like pfft.  Good one, mom.

Memory tests aren't important.. Which is why nobody cares to pass them.


Clearly we should all follow breaks medical and scientific advice, I mean they are experts right? I don't see any studies backing this load of shit story up, just propaganda, Ian works for Obama

your brain isnt finished growing until you are in your early twenty's, adding any foreign substance will likely have detrimental effects. that said, legalizing weed so we can have more effective controls over who smokes it could solve a lot of problems.

yes yes, i know, we have a legal drinking age and kids still manage to get booze but there still are not anywhere near as many bootleggers around as there once were. 

oh btw? i have been smoking weed for almost thirty years and i still retain control of my faculties. find someone who has been drinking [at the level i smoke weed] for thirty years and ill side by side a functional level test with them. let see how the research stands up.

I started smoking pot like in the 70's sometime, and like I have a Job and like "dude" I make enough money to buy more pot. Dude I still remember my mother - in - Law, How much more do I have to smoke to forget her. I know "Ludes" Lemon 714 baby, I still remember them too.  So your research is shit...


Many of you are too retarded to realize the joke in this article and just go off right away trying to protect the image of Marijuana. It's trying to prove a point that you didn't realize they repeating shit multiple times, using satire and you didn't realize.

Either way, smoking it still delivers cancer causing carcinogens. My uncle died this year at 47 from lung cancer. He only smoked pot - no cigarettes.

no, really? if you spend the better part of time being high and just laughing your ass off during the period when your brain is developing the most, of course it isnt going to turn out normally.

What about people that drink alcohol everyday for three years.  Or take ambien everyday for three years, or take hydrocodone every day for three years, or Oxycontin, or Nyquil...

Or what happens to the minds of those that watch everyday for three years.   The list goes on idiots.  Way ta go Break on contributing to the machine.  We knew we could count on you.

Oh Jeeze another Break sellout article pandering to the corporate machine. People are waking up to the lies. Alcohol is MUCH MORE DANGEROUS/UNHEALTHY, but you clowns and your big pharma masters just can't stand the thought of people not needing your $500 a week bullshlt prescriptions.

I "know someone" who has smoked since he was 14 and IQ has remained intact into his mid-30's, and he is a frigging aerospace engineer. Weed DOES impair short term memory, BUT it is NOT permanent, and weed is SAFER TIMES A THOUSAND than alcohol.

Why is liquor legal and weed not??? We all know which is worse for your health...... we just have to hope less and less people take your BS articles seriously and finally wake up.

@mykylcpreeeeeetty sure no doctor is going to prescribe oxys or other high test pain meds to a 15 year old, but thanks for coming out.

@COHockeyIt's like you're inside my head, man!   MUST DESTROY COHockey ON BEHALF OF BAYER!  MUST DESTROY!

@Mike-Emmons-39 @mykylc preeeeeeety sure there aren't too many kids walking into medical marijuana pharms on their own with prescriptions.  Just because something is considered legal or prescribed doesn't mean it can't be acquired and consumed.
