The Link Between Marijuana and Schizophrenia

Two components of marijuana have different effects on symptoms of psychosis. Delta-9 tetrahydocannabinol (THC) causes hallucinations and, in high enough doses, can cause temporary psychotic experiences, even in healthy people. Another chemical, cannabidiol (CBD), has anti-psychotic effects. Scientists hope to replicate the antipsychotic effects of CBD without triggering the risks of THC. – Ilene 

The Link Between Marijuana and Schizophrenia

Since the days of Reefer Madness, scientists have sought to understand the complex connection between marijuana and psychosis. Cannabis can cause short-term psychotic experiences, such as hallucinations and paranoia, even in healthy people, but researchers have also long noted a link between marijuana use and the chronic psychotic disorder, schizophrenia.

Repeatedly, studies have found that people with schizophrenia are about twice as likely to smoke pot as those who are unaffected. Conversely, data suggest that those who smoke cannabis are twice as likely to develop schizophrenia as nonsmokers. One widely publicized 2007 review of the research even concluded that trying marijuana just once was associated with a 40% increase in risk of schizophrenia and other psychotic disorders. 

But here’s the conundrum: while marijuana went from being a secret shared by a small community of hepcats and beatniks in the 1940s and ’50s to a rite of passage for some 70% of youth by the turn of the century, rates of schizophrenia in the U.S. have remained flat, or possibly declined. For as long as it has been tracked, schizophrenia has been found to affect about 1% of the population. 

One explanation may be that the two factors are coincidental, not causal: perhaps people who have a genetic susceptibility to schizophrenia also happen to especially enjoy marijuana. Still, some studies suggest that smoking pot can actually trigger the disease earlier in individuals who are predisposed, and yet researchers still aren’t seeing increases in the overall schizophrenia rate or decreases in the average age of onset. 

In recent months, new research has explored some of these issues. One study led by Dr. Serge Sevy, an associate professor of psychiatry at the Albert Einstein College of Medicine in New York City, looked at 100 patients between the ages of 16 and 40 with schizophrenia, half of whom smoked marijuana. Sevy and colleagues found that among the marijuana users, 75% had…

Can Dopamine Make Your Future Look Brighter?

Can Dopamine Make Your Future Look Brighter?

By John Cloud, courtesy of TIME

Tourism In Florida Falls Almost 10 Percent During Second Quarter

Humans have expended a great deal of intellectual energy over the past few thousand years trying to understand the morality (or amorality) of seeking pleasure. Most of philosophy begins with the question of what defines the (or a) good life. But what if the answer to what makes us happy comes down to how much of a particular chemical is circulating in our brain at any particular moment?

(As with risk taking, romantic love, religousness…. – Ilene)

The neurotransmitter dopamine isn’t quite that powerful, but evidence has been mounting for the past 40 years that its activity is key to helping the brain recognize experiences that cause pleasure. The more dopamine a certain event (having sex or eating ice cream, say) triggers, the more strongly that event gets hard-wired in the brain, and the more intensely your brain drives you to revisit it.

That knowledge also helps the brain figure out how much pleasure it can expect from future experiences and, therefore, influences virtually any decision you make about what you might like or not like: whether you should buy the red shirt or black one, whether you’ll enjoy watching Top Chef over Mad Men, whether you should leave your job or whether you should move in with your boyfriend.

Now a new paper in the journal Current Biology shows for the first time that by tinkering with levels of dopamine in the brain, researchers were be able to influence people’s future decisions in a reliable, predictable way. Led by Tali Sharot and Tamara Shiner of the the Wellcome Trust Center for Neuroimaging at University College London, scientists presented 61 healthy volunteers with 80 different vacation locations, such as Brazil, Thailand and Greece, and asked the volunteers to rate how happy they thought they would be visiting each place. Later, 29 of the participants were given 100 mg of levodopa (or L-DOPA), a drug that increases dopamine in the brain; the other 32 were unwittingly given a sugar pill. Forty minutes later, each participant was given a questionnaire about their emotional state, then a list…

Crazymaker: Journal of American Media and Lifestyle

Fun post for the evening, by Charles Hugh Smith, in case you missed it earlier. – Ilene

Crazymaker: Journal of American Media and Lifestyle

If you wonder why our society is so schizophrenic--look no further than Crazymaker Journal.

I happened upon a fascinating new online publication: Crazymaker, the Journal of American Media and Lifestyle. I have to say the content set me back on my heels; rarely do I see such an honest portrayal of the carefully mixed messages dished out as "news" and "entertainment".

crazymaker journal

Gregory Bateson addressed how a cognitive "double bind" could create a schizophrenic state of anxiety and dysfunction.

Their findings indicated that the tangles in communication often diagnosed as schizophrenia are not necessarily result of an organic brain dysfunction. Instead, they found that destructive double binds were a frequent pattern of communication among families of patients, and they proposed that growing up amidst perpetual double binds could lead to learned patterns of confusion in thinking and communication.

Human communication is complex; 90% of it is nonverbal (see also Albert Mehrabian) and context is an essential part of it. Communication consists of the words said, tone of voice, and body language. It also includes how these relate to what has been said in the past; what is not said, but is implied; how these are modified by other nonverbal cues, such as the environment in which it is said, and so forth.

For example, if someone says "I love you," one takes into account who is saying it, their tone of voice and body language, and the context in which it is said. It may be a declaration of passion or a serene reaffirmation, insincere and/or manipulative, an implied demand for a response, a joke, its public or private context may affect its meaning, and so forth.

This is an apt description of the craziness created by media/marketing messages every minute of every hour of every day in the USA. Bake a super-rich cake, and oh my, why are you so fat? Now you have to torture yourself with diets which don’t work.

Girls: want to look hot and sexy? if you don’t, you’re a loathesome loser.

Guys: not ripped with bulging muscles? Too bad--you’re a loathesome loser, too. Image and exteriors are everything!

The media profits from selling marketing/adverts. Marketing

Artistic tendencies linked to ‘schizophrenia gene’

A little off-topic, but this next article from New Scientist is quite interesting.  You can read the full article here.  (The how Goldman Sachs manipulates the market series will resume later.)

Artistic tendencies linked to ‘schizophrenia gene’

Salvador Dali 1939By Ewen Callaway

We’re all familiar with the stereotype of the tortured artist. Salvador Dali’s various disorders and Sylvia Plath’s depression spring to mind. Now new research seems to show why: a genetic mutation linked to psychosis and schizophrenia also influences creativity.

The finding could help to explain why mutations that increase a person’s risk of developing mental illnesses such as schizophrenia and bipolar syndrome have been preserved, even preferred, during human evolution, says Szabolcs Kéri, a researcher at Semmelweis University in Budapest, Hungary, who carried out the study.

Kéri examined a gene involved in brain development called neuregulin 1, which previous studies have linked to a slightly increased risk of schizophrenia. Moreover, a single DNA letter mutation that affects how much of the neuregulin 1 protein is made in the brain has been linked to psychosis, poor memory and sensitivity to criticism…

People with two copies of the neuregulin 1 mutation – about 12 per cent of the study participants – tended to score notably higher on these measures of creativity, compared with other volunteers with one or no copy of the mutation…

…Kéri speculates that the mutation dampens a brain region that reins in mood and behaviour, called the prefrontal cortex. This change could unleash creative potential in some people and psychotic delusions in others…

Crude Oil Cleared For Blast Off On This Dual Breakout?

Is Crude Oil about to blast off and hit much higher prices? It might be worth being aware of what could be taking place this month in this important commodity!

Crude Oil has created lower highs over the past 13-years, since peaking back in 2008, along line (1).

It created a “Double Top at (2), then it proceeded to decline more than 60% in four months.

The countertrend rally in Crude Oil has it attempting to break above its 13-year falling resistance as well as its double top at (3).

A successful breakout at (3) would suggest Crude Oil is about to mo...

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...
