Pot Smoking Lowers IQ

tp://www.bbc.co.uk/news/health-19372456


"Young people who smoke cannabis for years run the risk of a significant and irreversible reduction in their IQ, research suggests.

The findings come from a study of around 1,000 people in New Zealand.

An international team found those who started using cannabis below the age of 18 - while their brains were still developing - suffered a drop in IQ."

Excessive sneezing during childhood can probably be shown to lower IQ, if someone ever does the research. Note that they don't say the same about adult use. In fact, I believe a study done a while ago showed pot smoking increases IQ in middle aged men, if I remember correctly.

If we're going to wring our hands about drug use, let's look at meth and prescription drug abuse. Those are killing people. I don't think pot is entirely harmless or a miracle cure, but focusing on it instead of real problems like these make me question the motives (and funding) of those who make stories of single-study research. I don't mean you personally by this.

and that's what makes them think smoking pot while your brain is still growing and developing is ok.

perhaps the cause and effect are reversed.

most of the pot smokers i know didn't start until their early 20s ... haven't seen any IQ problems in my limited sample. the one i know who DID start in her teens, in high school, where she spent more time smoking pot in the desert with her friends, than she spent in school ... now she has some issues! i know, anecdotes aren't data.

They found that the non-tokers IQ's stayed the same or went up slightly. The light tokers had an average IQ increase of five points, more than the non-tokers. The heavy users had suffered an IQ loss of about four points.

The study further found that after abstaining from weed for three months the differences between the three groups' IQ levels disappeared.

sure-- while using, short term memory suffers. But the damage isn't permanent, as it is with alcohol and tobacco use.

and besides, cannabis opens up the brain to other kinds of intelligence which can't necessarily be measured by typical IQ tests. There may be advantages to use that we are yet unaware of in addition to the medicinal properties. After all, the brain has cannabis specific receptors, almost as if evolution selected us to use cannabis. It's pretty interesting.

Tue Aug 28, 2012, 02:42 PM
Aug 2012

You see just about any statement may be misleading if it is incomplete or somehow purposefully saying one thing when another is true. But when you put the word "deliberately" in there it changed the focus from the article, which may or may not be misleading, and focused it on the author (me) and accused me of doing something, purposefully misleading the audience, that in fact I did not do. So what you did was take what might have been a valid attack on the article and turned it into a personal attack on me. That is how language works. It is the most important thing you can do in you life is pay attention to what you say and say what you mean while avoiding saying things that you don't mean. I doubt that you meant to attack me, but that is in fact exactly what you have done with the inclusion of that one simple word.

Only a fucking moron would believe that smoking pot while your brain was still developing doesn't have any affect. I didn't need a fucking study to tell me that.

The study also says that it does not affect people who start smoking at age 18. So.. assuming your comment about "read it and weep" is a hilarious statement about your thoughts on legalization or pot use I'd say the study says go ahead ans smoke up as long as you are of age. Read it and weep indeed.

we're simply saying that we are not closing our eyes to it. Young people are going to listen to misogynistic music, smoke all kinds of things, drink, and have sex. It's called individuation. While kids are young they identify themselves by what their parents tell them to do. Eventually, they start thinking and making decisions for themselves. Most of them time when they are teenagers they do this by doing the exact opposite of what their parents tell them to do. The more we tell them not to do something the more they want to show their independence by doing it. We do have teach them about the dangers and let them know we care and that we're concerned, but the more dangerous we make it out to be the more they want to do it.

kids. My kid fell in with that crowd, his GPA is in the toilet, he failed his AP exam, he was SOL on his SAT's because he was stoned and he thinks in his universe he's getting into his top choice college and I should pay. Under the circumstance I'm not paying... and it all started with one mother and one kid who roped the lot of them in.... Parents and adults do promote it with their kids. It's one thing to be against criminalization for adults over the age of 21, it's quite another to just hand it over, and post after post I just see people glorifying it, I'm pretty fed up as a parent.....

I am sorry your kid is making it harder for himself to go to college. I have a seventeen year old who I happen to know is experimenting with some stuff I would much rather her not be experimenting with. I do worry about her being denied a spot in college, or being denied a job. I have talked to her, but quite frankly at this age they are going to do what they are going to do. This is the point in their lives when if they fall on their butt they have to figure out how to fix it for themselves. Your kid has made it more difficult for himself to get into college, but that doesn't mean he can't change that once he realizes he wants to change it for himself. You can't change it for him.

through the other adults in his life at the age of 15. We hear the same argument, they're going to do it anyways, so we just do it together. Honestly it makes me sick, if your kid goes that route they go that route but you don't need adults, a 59 year old adult giving them full permission and use of anything. So when I hear "So What" to studies like this, I just wonder if people realize these are children's brains, not adults. As parents we have no right to make them do anything, from drug testing to counseling, nothing. We are just financially responsible until 18.... and we can't take away the bad choices, our son is going to have to make it on his own and prove that at some point he can be a good student and get good grades, until that time comes, college is off the table as far as us paying for it.

Tue Aug 28, 2012, 07:38 PM

by an adult giving her drugs. We had a truly terrible year where she completely spiralled out of control - dealing, prostituting herself for drugs, sneaking out at night and catching rides into Chicago for adult coke parties and worse. The police caught her at a heroin party at IIT on the south side of Chicago and brought her home but warned they would arrest her next time. She entered a rehab facility the next day. I have never been so terrified.

She has a substance abuse problem. ANY drug is a problem for her. She's just lucky she didn't have time to try heroin there (or meth which the police also found at the party).

She's 15 now, 9 months clean and sober but I know from counseling that the younger they start, the easier it is for them to backslide. Furthermore, I know that some people just can't handle it, even pot.

We desperately need decriminalization for adults. But adults giving kids drugs should still be a criminal offense imho.



I hope your son can find his way and pull himself together.
