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…

By Joe Quinlan. Originally published at ValueWalk.

With the United States and China at loggerheads over trade, investors should be aware of the many economic ties binding the two countries.

Bitcoin Update - Bullish pressure present

Courtesy of Read the Ticker.

If Venezuela or Argentina conducted business in bitcoin then their savings and wealth would be a lot better off. Yes Bitcoin and Litecoin have been volatile over the last few years,  but nothing like Bolivar (Venezuela) or the Peso (Argentina). 

You say they could use the US dollar, yes maybe so, but those who use the US dollar have to the yield to the US Federal Reserve where as bitcoin is decentralized and those who use it yield to no one.

In the next 12 to 18 months the lightning network and atomic swaps logic will forge Bitcoin and Litecoin together as the go to crypto decentralized currency. Of course massive risk, so the investor should be warned you can lose all your funds.

Mapping The Market

Mistakes were Made. (And, Yes, by Me.)

Via Jean-Luc:

Famed investor reflecting on his mistakes:

Mistakes were Made. (And, Yes, by Me.)

One that stands out for me:

Instead of focusing on how value factors in general did in identifying attractive stocks, I rushed to proclaim price-to-sales the winner. That was, until it wasn’t. I guess there’s a reason for the proclamation “The king is dead, long live the king” when a monarchy changes hands. As we continued to update the book, price-to-sales was no longer the “best” single value factor, replaced by others, depending upon the time frames examined. I had also become a lot more sophisticated in my analysis—thanks to criticism of my earlier work—and realized that everything, including factors, moves in and out of favor, depending upon the market environment. I also realized...
