Link Between Marijuana and Psychosis Goes Both Ways

An anonymous reader writes with news of a study out of the Netherlands (abstract) about the link between psychosis and marijuana use. The researchers wanted to examine what caused the relationship — was marijuana use leading to psychosis, or did those suffering from psychosis have a higher tendency to seek out marijuana? As it turns out, they found evidence for both. From the article: "... using pot at 16 years old was linked to psychotic symptoms three years later, and psychotic symptoms at age 16 were linked to pot use at age 19. This was true even when the researchers accounted for mental illness in the kids' families, alcohol use and tobacco use. Griffith-Lendering said she could not say how much more likely young pot users were to exhibit psychotic symptoms later on. Also, the new study cannot prove one causes the other. Genetics may also explain the link between pot use and psychosis, said Griffith-Lendering."

Correlation not cause

Which is more likely: 1) People with psychological issues seek pharmaceutical drugs to help them stay calm and not screw up their lives even though they are hearing voices and other psychotic issues.

2) Drugs cause the problems - but no one ever noticed before.

3) Some idiot won't even consider option #1 and go right option #2 - without any evidence at all, let alone proof.

Note, I have kidney disease - and as such do not take pot, drink alcohol or do any other drug without my doctor's express advice. My body can't handle it - but I'm not stupid enough to think other people have the same problem I do.

Re:Wonder drug? I think not.

I'm a pretty heavy pot smoker myself and know potheads of all types. Smart, stupid, lazy, motivated etc. Just like the rest of the population. But, anecdotally I have always thought smoking pot (or doing any drug) at a young age was bad. I noticed that most people I know who used to smoke when they were young can't now because it makes them way too paranoid or zone out and shut down. People I know who started smoking when they were older don't see to have this issue. Myself included.
