      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. 
    • alicia waid
      alicia waid on 06 Apr 13
       
      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).

      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.

      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

      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).

  • The “baby blues” is the most minor form of postpartum depression. It usually starts 1 to 3 days after delivery, and is characterized by weeping, irritability, lack of sleep, mood changes and a feeling of vulnerability. These “blues” can last several weeks. It’s estimated that between 50% and 80% of mothers experience them.
  • Women with this condition suffer despondency, tearfulness, feelings of inadequacy, guilt, anxiety, irritability and fatigue.
  • A woman with postpartum depression may regard her child with ambivalence, negativity or disinterest.

      very important and can cause severe damage to the child. The lack of feelings of love and belonging in a child's first years can result in many behavioural and psychological problems in the future.
  • The depression can begin at any time between delivery and 6 months post-birth, and may last up to several months or even a year
  • Postpartum psychosis is a relatively rare disorder. The symptoms include extreme confusion, fatigue, agitation, alterations in mood, feelings of hopelessness and shame, hallucinations and rapid speech or mania. Studies indicate that it affects only one in 1000 births.
  • The exact cause of postpartum depression is not known.
  • One factor may be the changes in hormone levels that occur during pregnancy and immediately after childbirth.
    • Erin Waxman
      Erin Waxman on 05 Apr 13
       
      this is the most common thought cause of the illness
  • There is no one trigger; postpartum depression is believed to result from many complex factors. It is important, however, to communicate to women with postpartum depression that they did not bring it upon themselves.
  • One certain fact is that women who have experienced depression before becoming pregnant are at higher risk for postpartum depression.
  • The risk increases in women who have experienced 2 or more abortions, or women who have a history of obstetric complications.
  • a difficult relationship, lack of a support network, stressful events during the pregnancy or after delivery.
  • Therapy, support networks and medicines such as antidepressants are used to treat postpartum depression.

  • And so, like nicotine or orgasm or food or gambling, it can become a substrate for addiction as well.
  • This can indeed be a genuine addiction
  • Exercise has a dramatic antidepressive effect.

  • long-term improvements in mental function and is the single best thing one can do to slow the cognitive decline that accompanies normal aging.
  • a short-lasting, deeply euphoric state that's well beyond the simple relaxation or peacefulness felt by many following intense exercise.
  • there are different types of endorphins
  • that are synthesized within the brain and therefore could cause euphoria without crossing the blood-brain barrier.
  • The researchers found that this long run was associated with increased opioid release in the runner's' brains, particularly in the prefrontal cortex
  • and the anterior cingulate cortex and insula
  • It's likely that runner's high is not entirely mediated by the opioid system: Exercise also increases the levels of endocannabinoids, the brain's natural cannabis-like molecules, in the bloodstream.
  • Thus exercise-induced increases in endocannabinoid levels in blood are presumably mirrored in the brain and could also contribute to the euphoria of runner's high.

    Exercise is an addiction for some, but is also a great way to help with illnesses and depression. Exercise helps blood flow through the brain and keeps us healthy.

  • They activate cannabinoid receptors that already exist in our body, and our bodies themselves actually produce compounds called endocannabinoids
  • Creating oil from the plant or eating the plant is the best way to absorb cannabinoids. Smoking also alters the plant molecules; when cannabis is heated and burnt it changes the chemical structure and acidity of the THC, which in turn negates its therapeutic value.

    The site is credible because the illusions are explained by Associate Professor of the Department of Psychology in the American University in Washington DC. The site also allows you to alter the illusion to help you understand how it's formed.

    Wow, this illusion is crazy! I love how the site lets us explore the illusion in depth by giving us the tools to alter the illusion.

  •  Internet use does not pull people away from public places. Rather, it is associated with engagement in places such as parks, cafes, and restaurants, the kinds of locales where research shows that people are likely to encounter a wider array of people and diverse points of view. Indeed, internet access has become a common component of people’s experiences within many public spaces. For instance, of those Americans who have been in a library within the past month, 38% logged on to the internet while they were there, 18% have done so in a café or coffee shop.

    This is an interesting idea for a project: do all the screens in our lives connect us or isolate us?

      This website is very interesting because it explains that their is an architectural difference in the brain of a psychopath compared to a healthy brain. The areas that are different are the amygdala, which is associated with emotions, fear and agression, and the oribitofrontal cortex (OFC), which is responsible for the decision making. There is white matter that connects the amygdala and the OFC, which is called uncinate fasciculus (UF). They found a significant reduction in the integrity of the small particles that compose the UF of psychopaths compared to control groups of people with the same age and IQ. The degree of abnormality was significantly related to the degree of psychopathy.

  • significance of these findings cannot be underestimated
  • the biological basis of psychopathy remains poorly understood
  • To date, nobody has investigated the 'connectivity' between the specific brain regions implicated in psychopathy.
  • Earlier studies had suggested that dysfunction of specific brain regions might underpin psychopathy
  • amygdale
  • the degree of abnormality was significantly related to the degree of psychopathy. These results suggest that psychopaths have biological differences in the brain which may help to explain their offending behaviours.

    ScienceDaily is one of the most popular scientific news web sites since 1995. As of 1995, ScienceDaily has won the loyalty of the public (i.e. students, researchers, health care professionals, government agencies, educators and the general public). If all those members of our society can trust this website that has won multiple awards, so can I. I am a part of the 3 million monthly viewers that trust this website that proves to be very credible. I also found this website using www.sweetsearch.com which the student of Mrs. Bambic's psychology class of 2012 have been told is credible and used by many professionals around the world.
