 Minimal Relationship Between Cannabis and Schizophrenia, Says New UK Study
Concerns that the more potent varieties of cannabis may increase the risk of schizophrenia in young people prompted the UK government to reclassify cannabis from a class C to a class B drug last year.

But the evidence for the relationship between cannabis and schizophrenia or psychosis remains controversial. A new study has determined that it may be necessary to stop thousands of cannabis users in order to prevent a single case of schizophrenia.

Scientists from Bristol, Cambridge and the London School of Hygiene and Tropical Medicine took the latest information on numbers of cannabis users, the risk of developing schizophrenia, and the risk that cannabis use causes schizophrenia to estimate how many cannabis users may need to be stopped to prevent one case of schizophrenia. The study found it would be necessary to stop 2800 heavy cannabis users in young men and over 5000 heavy cannabis users in young women to prevent a single case of schizophrenia. Among light cannabis users, those numbers rise to over 10,000 young men and nearly 30,000 young women to prevent one case of schizophrenia.

That's just part of the story. Interventions to prevent cannabis use typically do not succeed for every person who is treated. Depending on how effective an intervention is at preventing cannabis use, it would be necessary to treat even higher numbers of users to achieve the thousands of successful results necessary to prevent a very few cases of schizophrenia.

Matt Hickman, one of the authors of the report published last week in the scholarly journal Addiction, said that "preventing cannabis use is important for many reasons - including reducing tobacco and drug dependence and improving school performance. But our evidence suggests that focusing on schizophrenia may have been misguided. Our research cannot resolve the question whether cannabis causes schizophrenia, but does show that many people need to give up cannabis in order to have an impact on the number of people with schizophrenia. The likely impact of re-classifying cannabis in the UK on schizophrenia or psychosis incidence is very uncertain."

Given the evidence of the medical efficacy of Cannabis, the fact that it is the only known cure for cancers, alzheimer's disease, epilepsy, the only real effective treatment for glaucoma, the safest medicine or pain management, not to mention the aid for depression and many mental ailments, why would anyone want to keep this medicine from sick people?

It is time the war on cannabis and its users ended, it is time to allow people to be cured instead of simply kept alive with addictive and damaging drugs that cure nothing.

When is the medical profession going to stand up for genuine cures against government religious beliefs that oppose science and kills.

When are medical professionals going to live up to the promise of 'First do no harm'?

It is time for truth in both medicine and government and the media need to step up to the plate and expose the lies that come from both.
