Imaging studies of marijuana’s impact on brain structure in humans have shown conflicting results. Some studies suggest regular marijuana use in adolescence is associated with altered connectivity and reduced volume of specific brain regions involved in a broad range of executive functions such as memory, learning, and impulse control compared to people who do not use.
Alaa, are these not likely with many kinds of drugs? Prescribed psychotropic drugs have the same effect.https://www.bmj.com/content/349/bmj.g5312/rr/775731
Any addition to oxygen that reaches the body's cells ((Except food of course)) will harm health in the short or long term.
Unfortunately if, marijuana is a very dangerous psychoactive substance, which has a high impact on the Central nervous system, not only that, but this in turn, causes psycho-social events, with great rejection by the community
It appears from the expert answers above that I will soon be unable to talk to any of my neighbours - since last week marijuana is available to anyone buying it anytime in this country (Canada). I can't believe that people are lining up to buy it and smoke it at home - in front of their children?- to see how they feel?

Medical records of the individuals addicted to marijuana and research results concerning the use of the weed have reflected that its impact on human brain is not really serious. For one thing, the drug may not cause clinical anxiety. However, the latest research findings released by the scientists indicate that marijuana could be directly responsible for such psychotic disorders as schizophrenia. The sad thing is that the results of the related experiments have been inconclusive. As an illustration, in searching for ways to prevent Alzheimer's disease, scientists have recently reported that a form of dementia can be helped by the use of the weed. The latest research findings released by the Salk Institute indicate that the compounds found in marijuana may help remove amyloid beta — a toxic protein associated with Alzheimer's disease . As a consequence, we see that countries like Canada have legalized the use of the pot .
Marijuana does not kill brain cells. In fact the ''cannabinoids'' found in marijuana may help in protection and restoration of brain cells.

I have seen people's attitude after smoking weed several times and I don't thing I will ever like to act in that manner for a second.
Damage brain or not, people are all over the streets suffering from different levels of ma..... I don't think i will want to take it for anything.
How knows it? Everyone have different opinion. In any case, I'm really curious what the truth is.

Good contributions and helpful links on this discussion. Thank you.
Question must be ,does computer damages the brain rather than any natural herb.
Yes. See the link below

The number of diseases which are treated with cannabinoids is growing up rapidly:
https://www.canabomedicalclinic.com/10-common-conditions-medical-cannabis-prescribed-for/
The pathogenesis of those diseases includes apoptosis. Hence, neuroprotection caused by cannabionids is proved rather than damage of neurons.
I think it is make valbale effect in the brain cell toll ot kill them is duch away that one lose memory

Thank you all for the wonderful scientific discussion ... Greetings
Arvind, do you have any further evidence to supply? I recently read an article about the establishment of Western Psychiatry in India during the 19th century (perceived of in the article as a form of colonialism) which dealt with European claims that marijuana use sent people insane-they termed it Marijuana Psychosis. Indian doctors later and since have labelled it a fantasy of the Europeans (many psychiatric claims are fantasy, in the above case evidence of top-down elitism as most of those judged as suffering from the affliction were Indian, not European. Similarly many proven psychiatric or brain diseases are advanced as scientifically proven when they were and remain scientifically unproven). Part of my research is to investigate these fantasies of medical professions in Europe and elsewhere.

Nihada, its very common for vastly different results to appear, seeming to contradict one another and when this occurs, apart from pointing out the contradictions, I tend to look deeper into the research methods employed. In these matters, often the research methods are self-predictive (it confirms an opinion already held, which I found when researching monoamine hypothesis). It may be there are implicit differences in the research anyway. Its also likely that both research methods are faulty.
Many West Indian friends of mine, coming from societies where marijuana use is part of the culture, pour scorn on such views insisting that as with any substance overuse can have bad effects on some people-as with coffee drinking, alcohol, and many substances routinely consumed by European societies.
Again, I think the implicit cultural difference between effects of recreational drugs (routinely seen as bad) should be added to the equation. Nihada, your examples, although convincing may be responding to that trope. As I am not interested so much in recreational as medical drugs, of which mounting evidence suggests numerous maleficent affects on the brain, my main contribution must be -the medical use of marijuana has long standing, traditional proof which is likely to be denied by researchers. In Arvind's example the proof is mainly laboratory based, and in Nihada''s perhaps not as conclusive as it pretends and I have read numerous articles dismissing the efficacy of MRI.
Please refer to the following article:

Abdullah, surely this paper has political connections and seems produced by an anti-cannabis lobby, stating that we are all doomed if cannabis is legalised. More recent reviews take on a more open viewpoint. Nevertheless, the overall view is that cannabis if smoked causes problems in teenage brains-but a great deal of the information suggests subjectivity towards the issue. Cannabis smoking is a political as well as a health matter. Alcohol can damage brains and as I wrote earlier clear evidence suggests the same of prescribed psychotropic drugs, but because doctors issue these there is less noise.
Better to take this stance against all drugs.

This is from a more recent post from the National Health Service in the UK. It is 4 years old but more recent than many posts here. This one assesses papers on the subject, underlining their flaws.
Everything that claims to be science, isn't science-everything that claims to scientifically assess a given issue does not actually do that!
Dickson, my recent research into the monoamine hypothesis made me realise that a number of papers around this and other related issues did not meet scientific and academic standards, and that has made me wary of other papers around difficult issues. One example> most papers I found and read on ECT surveys did not mention patients' views just their behaviour which by now I''ve understood as typical of psychiatric papers. Independent surveys suggest that coercion was taking place. We just have to be careful of scientific papers.
Stanley Wilkin Thank you for your brilliant scientific discussion ... Greetings

Each in ten smokers of the drug is more likely to take drugs. That the risk rises to one in six young people starting to abuse Arigona in adolescence.
My dad has an increased risk of bronchitis and a heart attack.
...Marijuana is damaging to the brains of teenagers, causing damage that cannot be undone. Marijuana sets the teens that use it on a different course in life, making it difficult for them to finish school, have good personal relationships, get a good job and so on - but they won’t realize it because their brains have been damaged. Scientists have proven that the IQ can drop as many as 8 points due to continued marijuana use.
Marijuana has a complex relationship with libido and sexual function.
Memory impairment from marijuana use occurs because THC alters how the hippocampus, a brain area responsible for memory formation, processes information. Most of the evidence supporting this assertion comes from animal studies. For example, rats exposed to THC in utero, soon after birth, or during adolescence, show notable problems with specific learning/memory tasks later in life. Moreover, cognitive impairment in adult rats is associated with structural and functional changes in the hippocampus from THC exposure during adolescence.
As people age, they lose neurons in the hippocampus, which decreases their ability to learn new information. Chronic THC exposure may hasten age-related loss of hippocampal neurons. In one study, rats exposed to THC every day for 8 months (approximately 30 percent of their lifespan) showed a level of nerve cell loss at 11 to 12 months of age that equaled that of unexposed animals twice their age.

As long as it is contaminated the pure oxygen, it means that it has a negative effect on the brain and other body parts
Mental Effects
Long-term marijuana use has been linked to mental illness in some people, such as:worsening symptoms in patients with schizophrenia—a severe mental disorder with symptoms such as hallucinations, paranoia, and disorganized thinking
