I’ve gone through periods in my life where I was a daily marijuana smoker mixed with years of not smoking at all. I’d say over the last 25 years I was a daily smoker for 7 years. I can’t say that marijuana has contributed to my paranoid delusions or not. Personally, I think having used ecstasy 10 times, one time injecting meth and a couple times smoking weed laced with god knows what was far more damaging than all those years of smoking marijuana. I do know that I was drinking myself sick once a week while I was in the Navy. I finally said that enough was enough and started growing/smoking weed everyday. I have never had a problem with alcohol since.

I miss getting stoned. I really hope that I’ll be able to sometime in the future again, but that is looking like less and less of a possibility. I got off the dopamine antagonist for a couple of months a couple months ago. After two months, I still couldn’t get high. My sex drive was back to normal, I was eating normally again and my head was clear so working was a real pleasure. I did wind up hearing voices and ended up in the hospital again though.

The only upside I see is that I can eat as much food with marijuana in it as I want. Tasty! No really, I’ve had some really good food with it in it.

A recent systematic review concluded that cannabis use increases risk of psychotic outcomes
independently of confounding and transient intoxication effects. Furthermore, a model of the
association between cannabis use and schizophrenia indicated that the incidence and
prevalence of schizophrenia would increase from 1990 onwards. The model is based on three
factors: a) increased relative risk of psychotic outcomes for frequent cannabis users compared
to those who have never used cannabis between 1.8 and 3.1, b) a substantial rise in UK cannabis
use from the mid-1970s and c) elevated risk of 20 years from first use of cannabis. This paper
investigates whether this has occurred in the UK by examining trends in the annual prevalence
and incidence of schizophrenia and psychoses, as measured by diagnosed cases from 1996 to
2005. Retrospective analysis of the General Practice Research Database (GPRD) was conducted
for 183 practices in England, Wales, Scotland and Northern Ireland. The study cohort comprised
almost 600,000 patients each year, representing approximately 2.3% of the UK population aged
16 to 44. Between 1996 and 2005 the incidence and prevalence of schizophrenia and psychoses
were either stable or declining. Explanations other than a genuine stability or decline were
considered, but appeared less plausible. In conclusion, this study did not find any evidence of
increasing schizophrenia or psychoses in the general population from 1996 to 2005″

There you go. Cannabis does not cause any extra cases of Schizophrenia when you actually bother to look for them.

As ever, show me the bodies, then I might see you in court.

In the USA barely 1% of the population at any given time is diagnosed with schizophrenia. According to NIDA (US drug war propaganda think tank), up to 50% of US 12th graders in 1997 had used Marijuana. If there was any actual connection between marijuana and mental disorder, we would have an epidemic on our hands.

At best, modern psychology is guesswork. We throw compounds at the brain and analyze the results. What’s worse, people have wildly variable response to the same compound. Our FDA will approve drugs that have clear risk of death as a side-effect and place a drug such as marijuana on Schedule I (no medicinal value, illegal) that is, at best, tenuously connected to schizophrenia. Even the most biased sources (NIDA, Drug Czar) have not used the “schizophrenia connection” in many years here in the USA. If there was any real science behind the idea, they would use it. In fact, recent studies further discredit it.
