      Cannabis is too easy to access (become more and more easy to access, as well).  People are under the influence that smoking cannabis is not bad for you, and that it is, in fact, better than smoking tobacco.  However, this is not the case, as researchers are starting to see that cannabis might actually be causing mental illnesses.

      It is believed that cannabis triggers the onset or relapse of schizophrenia in predisposed people, however this cannot be certain, because many of the people being researched on have taken other drugs, which makes it hard to determine wether the triggers are from the cannabis or from any of the other drugs.

      During a test (that occurred over 15 years), it was discovered that by smoking marijuana during adolescence, you are increasing your risk of developing schizophrenia.  However, they are not certain that marijuana is the only cause: Other drugs might be a factor too, and a few other concepts.

      In addition, research is showing that cannabis also has a relation with depression.  It was studied over a period of 15 years, and results show that by smoking cannabis, you are increasing your risk of developing a major depression.  It was also showed that the use of cannabis also increases the idea of suicide and inability to feel pleasure.

      Although only few studies were talked about in the National institution of Health, they are enough to prove that cannabis increases ones rist of developing schizophrenia AND depression.  The studies also provide very little support to prove that there is also a link between marijuana and mental health problems that are largely due to self medication (harder to prove).  These studies are not trying to say that if you smoke cannabis you will develop schizophrenia or depression, however it is saying that those who are more vulnerable will.

      It is important to note that those who use cannabis must reduce their usage if they want their risk of developing schizophrenia or depression to decrease.  It was estimated that if you were to have reduced your exposure to cannabis, the incidence of psychosis would have reduced treatment by as much as 50% (Dutch study).

      In a Swedish study, it was proved that the use of cannabis increases your chances of developing schizophrenia by 30%.

      With further analysis, it has been discovered that cannabis is the drug associated with the possibility of developing schizophrenia (and not the impact of other drugs).

      During another experiment, it was found that 59 people with a basic diagnosis of a psychotic disorder show a strong association with the use of cannabis and psychosis.  It is evident that the longer you've been smoking the drug, the more your symtoms will worsen(there is a higher chance), just like with any other drug.

      In New Zealand, it was discovered that people who smoke marijuana are three times more likely to develop schizophrenia, by the age of 15 or 18.

      An Australian study was also made that shows the more you smoke cannabis, the higher your rates of anxiety or depression might be.  It was proven that this link is more prone to young women than young men, however this was not proved in any other study (except the australian one).  
    • alicia waid
      alicia waid on 06 Apr 13
       
      It was proven, however, that any young human being that has used cannabis three times or more by the age of 18 is more likely to have some sort of depressive disorder by the age of 26! (And unfortunately, this was proved even to those that stopped smoking cannabis and got themselves under control.  After the first 3 times, it was too late).

      In a study following 2,000 tenns as they start to develop into young adults, it was proven that young people who smoke marijuana at least 5 times were twice as likely to develop psychosis over the next 10 years of their lives compared to those who didn't smoke.
    • alicia waid
      alicia waid on 06 Apr 13
       
      It was also proven that early marijuana use could increase the speed of the onset of psychosis by three years. (Those most at risk are youths who might have some family member that is dealing with schizophrenia, or any other psychotic disorder).

      These people who have family members affected by psychosis have approximately a 1 in 10 chance of developing the same condition themselves (even if they've never smoked pot).  However, if smoking marijuana, this doubles their risk (1 in 5 chance).

      A very popular study (nearly 50,000 young Swedish soldiers were followed for 15 years) showed that those who smoked marijuana at least once were more than twice as likely to develop schizophrenia as those who had never smoked marijuana.

      One of the many things that are still unknown is how marijuana might lead to psychosis.  There is a theory that marijuana interferes with brain development during adolescence and young adulthood, but this theory is yet to be determined.

      Although many things are still unknown about the relation between the adolescent brain and marijuana, one this is certain: As a teen, by smoking marijuana, you are increasing your vulnerability to psychotic thinking.

  • regular marijuana use increases the chance that a teenager will develop psychosis
  • increases the risk of developing schizophrenia

      This website is very interesting because it helps me understand some studies that are currently being done about the causes of schizophrenia. Scientists believe that several genes are a cause of schizophrenia, but these genes need to be combined with an environmental factor to result in schizophrenia. Also. they noticed that the brain of a person with schizophrenia has a different architecture than one without. For example, they tend to have less gray matter and the ventricles are larger.

      This website is great for my project because it partly explains the cause of schizophrenia. It talks about a molecular switch that controls the behavior of a protein. This protein increases vulnerability to schizophrenia and mood disorders when it is altered. This protein controls the regulation of new neuron development in the cerebral cortex and the programmed migration of these neurons, which is essential for the formation of the brain's architecture.

HMS Press Release - Deciphering the teenage brain - 0 views

Brain adolescent psychology teens mooseblog

  • “Teens are in a discovery mode,” says Frances Jensen, MD, an HMS professor of neurology. “They’re experiencing new things, and their brains are developing accordingly. There’s simply a lot going on in their brains.”
  • The teenage brain matures from back to front. The posterior regions, especially those above the spinal column, are largely responsible for motor control. Their earlier maturation helps account for the quick acquisition of locomotion and other movement skills by young people. Maturation of many sensory regions also occurs early, enabling a growing person to learn from the surrounding world. The maturing of the forward regions of the brain, particularly the frontal lobe, doesn’t occur until late adolescence or early adulthood; some researchers say the region’s maturation may not be complete until age 30.
  • The ease of learning that most teens enjoy, however, can carry a steep cost: addiction. “The brain builds itself as it responds to experiences,” Jensen says. “With teens who experiment with drugs, this can result in addiction. It’s the same pattern as learning—we want more, more, more.”
  • ...1 more annotation...
  • The challenge for parents, educators, clinicians and others who deal with teenagers is to determine whether their exasperating behavior is just the stuff of growing up or whether their moodiness and lack of judgment are indicative of a larger, perhaps pathological, problem. Many mental disorders begin to manifest during adolescence, including schizophrenia, anxiety, depression, eating disorders, and drug and alcohol abuse. “The key,” says Jensen, “is to be aware of what’s going on with your kids. Teens today are exposed to more stress than ever before, including drugs, alcohol, and violence. We all have to be mindful.”
  • Mason Brenhouse on 01 Feb 11
     
    This article was written by Scott Edwards of Harvard Medical School on the intricacies of the teen brain and what exactly is going on pertaining to the brain during adolescence. It states that throughout adolescence teens go through many drastic changes. Consequently, this development of the brain may not even be completely finished until the age of 30 in certain cases. It essentially gives the how and why to the volatile behavior that most teenagers acquire.
