Three separate studies presented different aspects of the issue at the association's 112th convention held this week in Washington. The researchers recommend: If legalization is considered, the concentration of THC should be monitored
The debate regarding the legalization of cannabis has been increasing in recent years, and therefore many studies are also being conducted on the subject. Some of the latest research was presented this week at a session on marijuana legalization at the 122nd annual meeting of the American Psychological Association in Washington.
A new study shows that frequent use of marijuana causes a negative effect on the minds of teenagers and young adults, including a decrease in cognitive ability, attention and memory, and it also reduces IQ. This is according to a study conducted by psychologists. "We must recognize that regular use of cannabis, at least once a week, is not safe and may end in addiction and neurocognitive damage, especially in young people." said Dr. Krista Liesdahl, director of the Brain Imaging and Neuropsychology Laboratory at the University of Wisconsin-Madison, who was part of the research team.
The use of marijuana in the US is on the rise, and according to data from 2012, 6.5% of high school students reported smoking marijuana daily, compared to 2.4% in 1993. In addition, 31 of the young people aged 18-25 reported using marijuana at least once a month. According to Liesdahl, people who become addicted to marijuana can lose six IQ points by the time they reach adulthood, according to a long-term study of 1,037 participants who followed them from birth to age 38.
Studies using brain imaging of regular marijuana users have shown significant changes in brain structure, particularly among adolescents, Liesdahl says. Abnormalities in the structure of the gray matter, which is related to intelligence, were found in 16-19-year-olds who increased their use of marijuana in the past year, she said, adding that these findings remain in place even after control studies that examined the main medical conditions of the participant, as well as his exposure to drugs by his parents, lag in development and learning disabilities.
"When considering legalization, policymakers must find ways to prevent easy access to marijuana and provide additional medical treatments for adolescents and young adults." saying. She also recommends that lawmakers regulate the levels of THC, the active ingredient in marijuana, with the goal of reducing neurocognitive effects."
"Some legal strains of marijuana have greater levels of THC than other strains," says Dr. Alan Bundy of Dartmouth College. THC is responsible for most of the psychological effects of marijuana. Some studies have shown that frequent use of marijuana with a high THC rate can increase the risk of acute and future problems of depression, anxiety and psychosis. "The studies show that the relationship between marijuana and mental illness can moderate if the frequency of use and the concentration of THC decrease." Bondi said. "Unfortunately, most of our knowledge about marijuana is based on subjects who smoked marijuana with a much lower concentration of THC than today." He calls for perfecting the intervention strategies for the treatment of addicts.
The study also shows that the permit for the use of medical marijuana caused a reduction in the perception of risk among teenagers. Dr. Bettina Fries, mPacific Institute for Research and Evaluation in California. . Fries presented a 2013 study of 17,482 teenagers in Montana, and found that marijuana use was higher in counties where residents voted more in favor of legalizing medical marijuana in a 2004 referendum. In the districts where the proposal passed (over 51%) the youth, the rate of users among youth was higher than the number of licenses for the use of Peruvian marijuana among patients in that district," said Fries.
Recently senior reporters in the New York Times published a call for the legalization of marijuana, but they also call for preventing its sale to young people under the age of 21 (See an article in Calcalist). And this week - a study in Britain reveals that heavy users of marijuana have a tendency to paranoid thoughts (See news in NRG)

"The religious wing on the right claims that the Jews, and even the leftists among them, are superior to all human beings."
That's not what they claim.
They claim that the Jews are superior to the Gentiles wherever they are. And rightly so. (As human beings, Jews and Gentiles, are all equal before God).
Father, please let go. (the response, I mean)
Nostradamus was right.
And you, the leftists, should not be ashamed of your distorted views - you should correct them.
There is no equality between the right and the left. After all, no matter what, one is right and the other is left. By definition they are opposite to each other. It's like saying that day and night are equal in all respects. If such logic was applied in science... humans would remain with the stick in hand and would not advance on a cultural and technological level.
In short, what is needed is for each side to respect the other side, and both sides to look for (within themselves) the things that are beneficial to both sides.
When the useful things are found - make sure that these things will be the bond that binds the two parties.
Malan, you are wrong and misleading:
Equality in education cannot exist since each person wishes to educate his children differently. The education system should serve everyone and it should. But even then, some will prefer it this way and some will prefer another.
The humanity of the people is also not equal. Some are merciful and some are cruel. What to do, people are very different from each other also in their humanity.
Certainly the right does not claim that all people are equal. On the contrary, he claims that they are different but the opportunities should be equal.
The right also believes that there is no one sentence for all scales of values. There are superior ladders and there are rickety ladders. For example, the Jewish scale of values (which sanctifies life) is better than the Hamasnik scale of values (which sanctifies death).
It seems to me that leftism does not meet even the most elementary tests of reality.

Nostradamus
Papa doesn't allow talking like that. Not pretty. If you are a good boy I will buy you a lollipop.
I don't agree with 90% of the comments here, but I would like to stop this discussion.
There are millions of such discussions, they are not going to contribute to anything. And in general it seems that this discussion is at a really low level and maybe even a troll is visiting it.
Those who really want to argue about right or left, should click on my name. There you can argue and spread your opinions as much as you want...
For lefties, then you are type 1. By the way, people are not equal, because cultures are different and so are races and abilities.
And if we force equality on the world, there will be endless wars, meaning the 1st type of the leftists will lead to the 2nd type.
That is, leftism brings destruction in any case and both types are equally destructive. You leftists dream of an unrealistic utopia like in science fiction books.
The road to hell is paved with good intentions.
Nissim, where did you get the idea that leftists are willing to sacrifice their children or any person?
One of the people, in order to have equal opportunities, it is necessary to have equality in the children's education. The axiom "all people are equal" is a generalization of the humanity of all people, not a work plan. Even leftists, like everyone else, see differences. The political right does not claim that all people are equal, on the contrary, for example, the religious wing of the right claims that the Jews, and even the leftists among them, are superior to all human beings. And the examples are many, in Israel and everywhere.
leftist,
A leftist says - all people are equal.
Yamani says - the people are different, but it is appropriate that the opportunities be equal.
In my opinion, the right-wing approach describes reality in the right light. The people, the cultures, the values and the customs are indeed very different from person to person, from nation to nation and from culture to culture.
But it is fitting that in a heterogeneous society (Israel for example) the opportunities given to everyone who is part of society and contributes to society should be equal. It's right.
Nostradamus
So your definition of a leftist is either a totalitarian or an anarchist who wants to destroy humanity.
It seems to me that according to your definition there are less than a million leftists in the world.
The connection between your definition and the standard definition of what a leftist is is so loose that I have to ask what is your definition of a rightist?
I do not know whether to laugh or cry.
The difference between us is genes that are slightly (very slightly) different and also we were both born into a different environment and therefore developed different opinions
Miracles,
I'm from the left side of the map but I'm also not ready to sacrifice my children in order not to hurt those who want to kill my children 🙂
Leftist
The difference between us is that I am not ready to sacrifice my children in order not to hurt those who want to kill my children....
Leftist
I am right-wing and think that all people are equal.
What Nostradamus wrote is a collection of nonsense that indicates an incurable right-wing.
Leftism has only a single principle, from which everything the leftist says is derived, and this principle is
All people are equal.
Nostradamus
You wrote that leftists have extreme views. I asked you who the leftists are. You answered me - except that they have extreme views.
Of course - extreme opinions that differ from your extreme opinions...
You asked me to define what leftists are and I explained type 1 - the extremists. Type 2 - the most extreme.
Nostradamus
That is, you claim that their goal is 'X' - so their goal is 'X'.
very deep…..
Nostradamus Jr
Indeed you see that you are faithful to the method of Papa Nostradamus. the Apple does not fall far from the tree.
THE NEW WORLD ORDER
There are two types.
1. The people who want to make the world homogeneous without nationalism, without independent opinions like Islam, total obedience to a single ruler, a world with one government, one economy, one currency, one language, without weapons for citizens to prevent resistance to totalitarianism, ignorant, poor, desperate people, Obedient, drugged-zombies. Re-education camps. In short, a kind of global communism.
2. The people who want to turn the world into anarchy, thereby destroying humanity for the sake of nature and animals. The rise of Islam, everyone will fight everyone, West against East, rich against poor, black and white and Asian, Latin, Muslim and Christian, roughly what is happening now in Syria and Iraq. Finally humanity will be completely destroyed or at least most of it will be left without technology and thus nature and the world will be preserved and restored.
Apparently these studies were done on viewers of Big Brother, Survivor, Dancing Star and all this garbage that is fed to our minds through the telly.
A television console also changes the brain and not necessarily for the better.
Nostradamus
Please define leftists.
This is the goal of the leftists, to turn the citizens into zombies without opinion and motivation
The health benefits of marijuana outweigh the disadvantages.
An overview of the studies (scientific - not psychological) can be obtained in the "Why" lecture (Hebrew University) delivered by Prof. Raphael Meshulam:

Miracles - no 🙂
Or did I not pay attention properly?
MouthHole
Did you mean - National Institute of Health?
interesting,
The second "research" is a presentation, sponsored by the National Institute on Drug Abuse (NIH)
Trying to show that apparently the use of cannabis by young people will increase "likely to continue to increase among youth".
The third study, which is indeed much more formal, only tries to check the growth percentage of cannabis use in countries where it is legal (or medically legal), by using a survey. In the study it is recorded that they did not reach unequivocal results, but assume that there will be an increase in use. This research was funded by the National Institute on Alcohol Abuse and Alcoholism (NIAAA)
Regarding the increase in drug use among teenagers, I think we should continue to monitor with concern, but there is still a chance that the increase is only due to all the buzz around the drug. I'm personally optimistic that it will be an adult drug (but what do I know), here's another survey: https://www.colorado.gov/pacific/cdphe/news/news-new-survey-documents-youth-marijuana-use-need-prevention
This survey shows a decline in use among young people in the state of Colorado! The country where it is made legal. The young people say it's not cool. And they see a lot of adults doing it, so not special anymore.
And here is another study that shows that in Colorado fewer young people are using the drug in Colorado:
http://washingtonexaminer.com/so-far-colorados-teens-are-actually-using-marijuana-less/article/2551843
And another study that shows that there is a devaluation of drug use in countries that allow the drug.
The first study talks about the harms of marjuana among young people. But he relies on previous studies that were already known and does not innovate anything...
