      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).

      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).

      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).

Love and Addiction: 4. "Love" as an Addiction - 0 views

addiction love relationship ego feeling

shared by Chrissy Le on 09 Apr 12 - No Cached
  • a human relationship can be equivalent psychologically to a drug addiction.
  • Chein, Winick, and other observers interpret drugs to be a kind of substitute for human ties. In this sense, addictive love is even more directly linked to what are recognized to be the sources of addiction than is drug dependency.
  • Freud noted important parallels between love and another psychologically compelling process—hypnotism.
  • ...25 more annotations...
  • From being in love to hypnosis is evidently only a short step.
  • Love is an ideal vehicle for addiction because it can so exclusively claim a person's consciousness.
  • Someone who is dissatisfied with himself or his situation can discover in such a relationship the most encompassing substitute for self-contentment and the effort required to attain it.
  • When a constant exposure to something as necessary in order to make life bearable, an addiction has been brought about, however romantic the trappings. The ever-present danger of withdrawal creates an ever-present craving.
  • Since the person who addicts himself to a lover has essentially the same feelings of inadequacy as the drug addict, why should such an individual choose another person, rather than a drug, for the object of his addiction
  • found that sexual relationships in the lower class tend not to involve as great a degree of life-sharing.
  • "The lower class person . . . is less dependent on people, and more oriented toward those gratifications which can be achieved without complicated cooperation of other human beings."
  • The latter can be defined as the need to cling to one human object for love and support. That object may not even be a true person, but only a conception of a person.
  • When people are economically comfortable but still sense a large deficiency in their lives, their yearnings are bound to be more existential than material. That is, these yearnings are tied into their basic conception of and feelings about themselves
  • A person feeling this inner emptiness must strive to fill it. In relationships, this can only be done by subsuming someone else's being inside yourself, or by allowing someone else to subsume you.
  • The result is a full-fledged addiction, where each partner draws the other back at any sign of a loosening of the bonds that hold them together.
  • The relationship was an addiction. F. Scott Fitzgerald and Sheilah Graham sealed themselves off from the outside world by neglecting their work and by dropping all their other personal relationships in Hollywood.
  • The belief which underlay this feeling—and all of the relationship—was expressed by Graham when she said that "my living began when he arrived." If there is a need to participate in every aspect of another's life, its conclusive form is the complete control of or reliance on another, so that one person does not exist without the other's being there, too. This is the essential similarity to drug addiction, where a person feels he is living only when he is on the drug. The ultimate statement of the desire to be consumed by love is in the last passage quoted from Graham, where she wanted to crawl into Scott's mind, lose her consciousness in his, and form one human entity out of two incomplete beings.
  • The sadistic person is as dependent on the submissive person as the latter is on the former;
  • The difference is only that the sadistic person commands, exploits, hurts, humiliates, and that the masochistic person is commanded, exploited, hurt, humiliated. This is a considerable difference in a realistic sense; in a deeper emotional sense, the difference is not so great as that which they both have in common: fusion without integrity.
  • Above all else, these extreme emotional reactions conclusively establish that the relationship was an addiction. All along, the lovers' actions toward each other were dictated by their own needs. Therefore, when their connection was severed—even temporarily—they had no basis on which to relate. Each was incapable of respecting, or even conceiving of, the other in his or her own terms, as continuing to live his or her own life. It was impossible for either to be concerned about the other's well-being; if the one lover wasn't there to satisfy the other's needs, then he or she ceased to exist.
  • Because an addiction is sought only for the total experience it provides, it can only be accepted emotionally in that form.
  • Love is the opposite of interpersonal addiction. A love relationship is based on a desire to grow and to expand oneself through living, and a desire for one's partner to do the same.
  • Anything which contributes positively to a loved one's experience is welcomed, partly because it enriches the loved one for his own sake, and partly because it makes him a more stimulating companion in life.
  • If two people hope to realize fully their potential as human beings—both together and apart—then they create an intimacy which includes, along with trust and sharing, hope, independence, openness, adventurousness, and love.
  • If a person loves only one other person and is indifferent to the rest of his fellow men, his love is not love but a symbiotic attachment, or an enlarged egotism.
  • the tendency to regard social partners as commodities. People who show this orientation "fall in love when they feel they have found the best object available on the market, considering the limitations of their own exchange values."
  • Fromm therefore stresses that the respect inherent in all love requires a lover to think, "I want the loved person to grow and unfold for his own sake, and in his own ways, and not for the purpose of serving me."
  • An independent, open person exploring life seriously will instinctively (if not consciously) consider whether someone has anything of substance to add to his or her existence.

      This explains the science behind the difference in brain activity between adults and teens. The adult neurons reacted with less excitation and higher inhibitory. 
  • The extreme difference in brain activity provides a possible physiological explanation as to why teenagers are more prone than adults to rash behaviour, addiction, and mental diseases
  • "This could intensify the effect of reward on decision making and answer several questions regarding adolescent behaviour,
  • The type of erratic activity in the cortex that she and Sturman observed could aggravate these conditions at a time when the maturing brain is vulnerable.

    This article is interesting because it explains the science behind the difference in brain activity between adults and teens. It then gives a physiological explanation as to why teens are more prone then adults are to addiction, mental diseases, behavioural disorders and psychological illnesses. It speaks about different parts of the brain, relating them to their specific activities and then explains how this effects the teen negatively, while comparing everything with adults.

  • “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.

  • Sixty-two percent of the survivors who developed PTSD still had symptoms at their two-year visit.
  • Half of this same group was taking psychiatric medications, and 40 percent had seen a psychiatrist in the two years since being hospitalized with ALI.

      Even with both types of treatments, many patients were still suffering from PTSD
  • The researchers also found that patients with depression before hospitalization were twice as likely to develop PTSD,

      Similar statement to my research from Harvard Medical Center. 
  • This inflammation may lead to a breakdown in the blood-brain barrier, which alters the impact on the brain of narcotics, sedatives and other drugs prescribed in the ICU.
  • Bienvenu says patients who have these risk factors need special attention. Simply educating them and their primary care doctors about the increased risk for PTSD would be a step in the right direction, he adds.

      This is one of the most simple tactics i have read on preventing PTSD
  • he symptoms fall into three categories: reliving the traumatic experience (flashbacks, nightmares), avoidance (feeling numb, detached, staying away from people and places that serve as reminders of the experience), and hyperarousal (being easily startled, having difficulty sleeping, irritability).
    • Zach Fenlon

      These are the exact same symptoms that The Harvard Medical Institution describes. 
  • "psychological rehab" now deserves attention.
  • The intervention reduced PTSD symptoms by helping patients make sense of their ICU memories,

      A proven way to reduce PTSD. Very interesting.

  • It's a catch-22 manufactured by the Drug Enforcement Agency: marijuana is illegal because the DEA says it has no proven medical value, but researchers have to get approval from the DEA to research marijuana's medical value.

      Many people try hard drugs for example and do not get addicted. Why are some more vulnerable to these addictions than others? 
    • Julian Posteraro

      The future of research on addiction is both positive and negative. We are finding more and more reasons about why we all get addicted to certain things.

  • because emotions have evolved in specific contexts.
  • Categorically denying emotions to animals because they cannot be studied directly does not constitute a reasonable argument against their existence.

      To deny that something is real without first investigating its existence is not good science.

      This means a type of behaviour related to a species, like mating behaviour for example.
  • My goal is to convince skeptics that a combination of “hard” and “soft” interdisciplinary research is necessary to advance the study of animal emotions.
  • broadly defined as psychological phenomena that help in behavioral management and control
  • Likewise, no single theory of emotions captures the complexity of the phenomena called emotions
  • It is important to extend our research beyond the underlying physiological mechanisms that mask the richness of the emotional lives of many animals and learn more about how emotions serve them as they go about their daily activities

      Ignore the previous sentence because this one explains it: the study of emotions needs to focus more on how they help us in life and less on the biology of them.

  • B. F. Skinner

      Skinner was a pioneer in behaviour conditioning. He taught that emotions, because we can't measure them, are not important to understanding behaviour.
  • Why then are there competing views on the nature of animal emotions? In part, this is because some people view humans as unique animals, created in the image of God
  • researchers studying animal behavior came to realize that there was too little in studies of animal emotions and minds that was directly observable, measurable, and verifiable, and chose instead to concentrate on behavior because overt actions could be seen, measured objectively, and verified
  • Most researchers now believe that emotions are not simply the result of some bodily state that leads to an action
  • William James and Carl Lange
  • James and Lange argued that fear, for example, results from an awareness of the bodily changes (heart rate, temperature) that were stimulated by a fearful stimulus.
  • Walter Cannon's criticisms
  • there is a mental component that does not have to follow a bodily reaction
  • drugs producing bodily changes like those accompanying an emotional experience
  • do not produce the same type of conscious experience of fear

      Substitue 'circuit' for this word
  • . Each is connected to the other two but each also has its own capacities
  • current research (LeDoux 1996) indicates that all emotions are not necessarily packaged into a single system, and there may be more than one emotional system in the brain.
  • Secondary emotions are those that are experienced or felt, evaluated, and reflected on. Secondary emotions involve higher brain centers in the cerebral cortex.

      Ethology is the study of animal behaviour and mind
  • cognitive ethologists want to know what it is like to be another animal.
  • concerns how emotions and cognition are linked
  • A sense of self in the act of knowing is created,
  • various brain structures map both the organism and external objects
  • I am inclined merely to delete it [the mental realm] from biological explanation, because it is an entirely private phenomenon, and biology must deal with the publicly demonstrable.”
  • abanac postulated that the first mental event to emerge into consciousness was the ability of an individual to experience the sensations of pleasure and displeasure
  • Examples of animal emotions
  • Social play
  • Studies of the chemistry of play support the idea that play is enjoyable.
  • dopamine (and perhaps serotonin and norepinephrine)
  • rats enjoy being playfully tickled.
  • grief in geese
  • grief and depression in orphan elephants is a real phenomeno
  • It is unlikely that romantic love (or any emotion) first appeared in humans with no evolutionary precursors in animals
  • common brain systems and homologous chemicals underlying love that are shared among humans and animals
  • No one discipline will be able to answer all of the important questions that still need to be dealt with in the study of animal emotions
  • However, research that reduces and minimizes animal behavior and animal emotions to neural firings, muscle movements, and hormonal effects will not likely lead us significantly closer to an understanding of animal emotions.
  • All research involves leaps of faith from available data to the conclusions

      What do you think about this sentence?
  • studies of the behavior of captive animals
  • Field work also can be problematic. It can be too uncontrolled to allow for reliable conclusions to be drawn.
  • behavior is primary; neural systems subserve behavior
  • Emotions are an integral part of human life, so why not for other animals?
  • in many instances, differences in degree rather than differences in kind.
