Excessive Weed can suggest a psychosis in – fact, increasingly, scientific data of the last years. Now a large Multicenter study in a Brazilian and ten European cities, as much in some places, the use of cannabis on incidence of psychosis, the impact of.
On all of the studied cities according to the study, every fifth new psychosis case, a connection to daily cannabis use, in the case of each active substance Tetrahydrocannabinol (THC) on Cannabis with a high content of psycho. The differences between the cities are large. In Amsterdam, the Figures are particularly striking: 40 percent of all new psychosis cases associated with daily Smoking Pot, in combination, 50 percent with a high THC content.
effect on first day of the conference Switzerland
"Our data for the first Time how cannabis use influenced the incidence of psychotic disorders on the population level show", Marta Di Forti from the Institute of psychiatry, psychology and neuroscience at King's College London, in a message quoted. She is the first author of the study, recently published in the journal "The Lancet Psychiatry".
The results are likely to influence in Switzerland the discussions about a change in the law that health has transferred Minister Alain Berset in front of a good three weeks to the Parliament for consultation. An experimental article should allow cities, limited in scope and scientifically accompanied to test the sale of Cannabis. In Switzerland, around every third Person has consumed ever Cannabis. In the case of the 15 - to 24-Year-old Smoking weed, against five per cent, according to its own information almost on a daily basis.
The researchers Marta Di Forti, compared to 900 patients over the age of 18 years old, the diseased, for the first time in a psychosis, with a similar-sized control group. From this they deduced that daily cannabis users, the risk of psychosis is three times as high as in the case of cannabis abstinent. Who used regularly for highly potent products, even had a five-fold increased risk. The researchers defined a THC content of about 10 percent as a "highly potent". In Switzerland, marijuana (dried buds), which was ensured by the police is, on average, just under this limit where the fluctuations are large. When hashish (resin) is the value of funds at 19 percent.
Without Cannabis with a high THC less psychosis
Whether Cannabis actually leads to psychosis, is not yet decided for sure. The authors of the current study and many scholars hold, however, the evidence from numerous studies, there is enough conclusive. You yourself found the connection that the common daily consumption, and highly potent varieties of cannabis, were the higher psychosis rates.
Di Forti and colleagues have calculated what would happen if high-potent Cannabis were to disappear from the market: a Total of 12 percent of the first disorders to psychosis could be prevented in London up to 30 per cent, and in Amsterdam even 50 percent. "It is an important public health consideration, in addition to the potential medical properties of cannabis was also the possible side effects of daily cannabis share to take into account consumption, in particular in the case of highly potent varieties," the authors write.
The British researchers for their publication a lot of praise. Also by Stefan Borgwardt, chief physician and Deputy Director of the Department for adults of the Psychiatric University clinics (UPK) Basel: "This is a very relevant study of the most established research group in the field of cannabis research in psychosis." You acknowledge that daily use of high potency plant and beginning at a young age have a negative effect on the Psyche. "The large number of cases is likely to persuade former doubters," says Borgwardt.
What is better: restriction or legalization?
The neuro-psychiatrist with the study's authors agree that cannabis use can actually lead to psychosis. "There are many studies that such a causality seem plausible." He could see it in his clinic, Where the majority of young psychosis patients consume intensive Cannabis. Nevertheless, Borgwardt admits: "in theory, but it is still possible that the assumed causality is reversed, because patients consume with a predisposition for a psychosis more likely in Cannabis."
the results of The Multicenter study are also valid for Switzerland, says Borgwardt. He emphasized, however, that this does not imply that whether or not legalization or restriction were the correct response to the risks of Cannabis. The neuro-psychiatrist is diplomatic: "The study allows for both conclusions."
