Study Shows Heavy Adolescent Pot Use Permanently Lowers IQ

http://www.forbes.com/sites/travisbradberry/2015/02/10/new-study-shows-smoking-pot-permanently-lowers-iq/

Marijuana smokers have long been characterized as dimwitted and slow. They tend to shrug off these stereotypes as artifacts of how they are when they’re on the drug. If you’ve ever had the misfortune of enduring a pot smoker who takes you through the “beneficial” effects of marijuana on the brain, then you’ve likely wondered if the stereotype is true. As it turns out, it is.

A study more than thirty years in the making found that smoking marijuana permanently lowers intelligence, or IQ. Frequent pot smokers (even those who had given up marijuana) tended to have deficits in memory, concentration, and overall IQ. The reduction in IQ for those who smoked pot heavily prior to age 18 was most pronounced: an average of eight points. An eight point reduction in IQ is enough to have a significant, negative impact upon your life. To put it into context, consider that individuals with an IQ of 110 have an average net worth of $71,000 and individuals with an IQ of 120 have an average net worth of $128,000. It looks like smoking pot can lower your tax bracket.

>> No.7065299

$128,000. As if that's a lot. Why do you fuckers always think so small? Why is everyone setting mediocrity as their goal?

Also not surprising that heavy weed smokers have a 'drop' in IQ. Higher IQ individuals are probably too busy doing shit in school to have time to be heavy consumers of weed.

I wouldn't be surprised if working in McDonalds for thirty years lowered your IQ 8 points, either.

On this basis alone I can kind of understand making pot illegal.

And Indian civilizations had thousands of years to adapt to weed. Guess what? Ronald Reagan forced India to make it illegal in the 80's. Also, it was widely prevalent in the middle east and even europe and still is in countries like Egypt to this day. This isn't about culture at all, but rather alcohol industrialists not wanting their business harmed. Incidentally, hemp was the reason marijuana was banned in the first place in the US.

So basically you're saying that a grandfather clause should exist for alcohol in europe because of historical reasons.

Right, I'm just going to greentext the numerous ways in which you are wrong.

>thinking Europe was a monolithic entity through a history of thousands of years
>thinking cocaine and opium weren't legal till a century ago
>thinking Alcohol and even tobacco were always legal in Europe
>thinking being adapted to alcohol over marijuana is a thing
>not knowing that Mariujuana only affects humans because of a special receptor in the brain i.e. adaptation


Besides, that wasn't even my point. People will always protect their vested interests, nobody wants to give up power, money or anything else >for free.
Marijuana is the main competitor to alcohol in both usage and effects (both used for socialization and self-medication).
Do you think the alcohol industry cares if the democrats or republicans are in power? They donate to both so they can have their vested interests and protect them too, and it is the same in whatever european country you can think of. The government-industry nexus is a real thing and is not limited to alcohol at all.

inb4 b-but this is only America and not Europe
Well good thing that America isn't the most powerful country and it hasn't directed the world's drug policy for 50 years or anything.

/thread

>>7065481
You know, I was going to make a point that upregulation of alcohol dehydrogenase doesn't make alcohol less toxic but that's exactly what it means.

However, we can do things like go to this (http://www.who.int/substance_abuse/publications/globalstatusreportalcoholprofiles/en/)) website and actually compare rates of alcohol dependence as compiled by the WHO.

Germany - 6% / 1.5%
France - 13% / 4.1%
Japan - 8.4% / 0.7%
USA - 10.8% / 4.8%
India - 6.8% / 0.7%
Indonesia - 1.7% / 0.3%
Russia ~ 37.1%
UK - 7.5% / 2.1%

male / female respectively. I'd say it has a lot more to do with culture and socioeconomy than biology.

I would hate to see what Russians are like with pot.
I'm not saying it's necessarily justified to outlaw weed, or even a smart move - personally I like the nederlands approach - my only point above was that it's not entirely inconsistent to ban weed and not alcohol for US/europes because they're two entirely separate issues. Talking about US because Forbes.com and europes because US is from europe.

Those values aren't taking population subsets into account, which is of course what is significant.

I know what anon is getting at, but I doubt social alcohol consumption resulted in epigenetic mutations selecting for increased ethanol metabolism/tolerance. It's a "chicken or the egg" scenario and he is trying to use this as evidence for alcohol consumption being "safer" than marijuana usage among Europeans, which is quite simply absurd based on all available metrics.

Marijuana use could impact neurological function, but I would never consider this small study and its faulty methodologies to be convincing.

Considering the fact that 100% employment isn't possible at all, you taking a job has a negative outcome for someone. Even if it was possible, the extra time someone has to wait for a job is also a negative. You affect someone else negatively, which is what his point was, which is a stupid point because people would be paralysed if everyone followed it to the letter as some sort of prime directive.
