In a new study, scientists in London, Ontario have discovered that early marijuana use may result in abnormal brain function and lower IQ. Marijuana is the most commonly used illegal substance in the world. Previous studies have suggested that frequent marijuana users, especially those who begin at a young age, are at a higher risk for cognitive dysfunction and psychiatric illness, including depression, bipolar disorder and schizophrenia. Dr. Elizabeth Osuch, a Scientist at Lawson Health Research Institute and the Dr. Joseph Rea Chair in Mood Disorders at the Schulich School of Medicine & Dentistry at Western University, is a Canadian leader in studying both mood and anxiety disorders and the effects of marijuana. "Many youth in our program use marijuana heavily and, despite past research, believe it improves their psychiatric conditions because it makes them feel better momentarily," said Dr. Osuch, who is also the Medical Director of the First Episode Mood and Anxiety Program (FEMAP) at London Health Sciences Centre. "For this reason, we decided to study the effects of marijuana and depression on psychiatric symptoms, brain function and cognitive function." Dr. Osuch and her team recruited youth in four groups: those with depression who were not marijuana users; those with depression who were frequent marijuana users; frequent marijuana users without depression; and healthy individuals who were not marijuana users. In addition, participants were later divided into youth who started using marijuana before the age of 17 and those who began using it later or not at all. Participants underwent psychiatric, cognitive and IQ testing as well as brain scanning. The study found no evidence that marijuana use improved depressive symptoms; there was no difference in psychiatric symptoms between those with depression who used marijuana and those with depression who did not use marijuana. In addition, results showed differences in brain function among the four groups in areas of the brain that relate to reward-processing and motor control. The use of marijuana did not correct the brain function deficits of depression, and in some regions made them worse. Of additional interest, those participants who used marijuana from a young age had highly abnormal brain function in areas related to visuo-spatial processing, memory, self-referential activity and reward processing. The study found that early marijuana use was also associated with lower IQ scores. "These findings suggest that using marijuana does not correct the brain abnormalities or symptoms of depression and using it from an early age may have an abnormal effect not only on brain function, but also on IQ," said Dr. Osuch. With past research suggesting a genetic role between marijuana use and depression, Dr. Osuch and her collaborators at Western University's Robarts Research Institute also conducted genetic testing on participants. They discovered that a certain genetic variation of the gene that produces Brain Derived Neurotropic Factor (BDNF) was found in greater proportion in youth who used marijuana from an early age. BDNF is involved in brain development and memory, among other processes. "This is a novel finding that suggests this genetic variation may predispose youth to early marijuana use," said Dr. Osuch. However, Dr. Osuch notes that this study had a small number of participants. These genetic results are therefore tentative and need to be verified with a larger study with more participants.

No adults in their right minds want their kids using this stuff.
That explains some behaviours but you need to explain what the HELL happened to you? Someone throw a tater at your head?
No reason is given for the bias of excluding healthy individuals who were marijuana users. They only included mj users without depression, and excluded healthy ones. Cooked, like "Climate Change" studies. Junk science. It's a rigged study. Yellow journalism !!! I doubt that it does to you. Therefore I will amplify for your edification in what no doubt will prove to be a futile attempt to improve you morally and intellectually. I shall begin by informing you that marijuana is the most abused drugs in the world, or at least among the very highest. It contains over 400 chemicals and the one chemical that produces intoxication is tetrahydrocannabinol (THC). THC creates the mind-altering effects that classifies marijuana as a Schedule I Controlled Substance, “having no currently accepted medical use in the United States, a lack of accepted safety for use under medical supervision, and a high potential for abuse.” Next, I shall advise you that marijuana intoxicates and causes changes in the body and the mind and it is known to create addiction or dependence. You will hear potheads say that since marijuana is a plant, then it’s “natural” and therefore it’s harmless. That is a false notion since there are many “natural” plants such as hemlock that are poisonous and can kill. Finally, I shall conclude by imparting knowledge to you that smoking pot and inhaling the smoke into your lungs is definitely not “natural” and can be harmful to your body like smoking tobacco. It has been found that smoking one joint gives as much exposure to cancer-producing chemicals….the same as smoking four to five cigarettes. The mental consequences of marijuana use are equally severe. Marijuana smokers have poor memories and mental aptitude. Studies have shown that people who smoke marijuana found abnormalities in the brain which related to emotion, motivation and decision-making. All this begs the question….are you one of those who has suffered abnormalities to the brain caused by smoking pot?
I could have told them that, Muslims are allowed to use marijuana and look at the result, Europe filled with deadbeats and the middle east in flames and it makes you very, very, paranoid
Complete rubbish. Where did you get that? How long have you run around spreading that lie? Look at the result of someone who can't be bothered to check basic facts. The US is filled to the brim with armchair experts- and you're turning into a 3rd world country. Ever been to Dubai? Compare their main airport to any in the US. Answer: It is haram [religiously forbidden] to use narcotics in any way because it results in considerable adverse effects in terms of personal health and social cost. By the same token, it is haram to deal in narcotics in any way, i.e., carrying, transporting, storing, selling, buying, etc. https://themuslimvibe.com/faith-islam/in-practice/what-does-islam-say-about-marijuana Remember what even your crooked corrupt despicable own government says about Cannabis: Cannabis has been used for medicinal purposes for thousands of years Chemical components of Cannabis, called cannabinoids, activate specific receptors throughout the body to produce pharmacologic effects, particularly in the central nervous system and the immune system. https://www.cancer.gov/about-cancer/treatment/cam/hp/cannabis-pdq
don't spread your Muslims lies here, how many Muslims are drug runners, hassish derived from marijuana has been used by Muslims for centuries, what is it you think they smoke in their pipes
Loads of hash is supplied to Europe via an entry point in southern Spain. It comes from north Africa.
Kids should not be using pot, alcohol, or any other drug. Since they for years have been reporting that they can get pot more easily than beer or cigarettes, it seems the best way to keep a drug out of kids' hands is to legalize it for adults only (which gives sellers an incentive to not sell to kids).
A government strong enough to impose your standards is strong enough to ban them. This explains the unusual behavior of the African elected and re-elected by the over-medicated idiots who vote.
Liberals are a lot like Slinkys, they're good for nothing but they bring a smile to your face as you shove them down the stairs.

Muslims are allowed to use marijuana and look at the result
Question 1392: What is the ruling in the matter of using narcotics, such as hashish, opium, heroin, morphine, and marijuana, be it by way of eating, drinking, smoking, injecting or applying them anally? And what is the view on selling, buying, and dealing in them in general, i.e., carrying, transporting, storing, or smuggling?
