The findings of a new study have revealed a link between smoking high potency marijuana and an increased risk of developing certain psychiatric disorders. The researchers from the Institute of Psychiatry, Psychology and Neuroscience at King’s College in London performed the study and published it too in the journal Lancet Psychiatry.
Eight hundred people between 18 to 65 years of were observed by the scientists for this study. It is reported that 410 people had reported at least one episode of psychosis and the rest of 370 had not and were otherwise healthy and used as a control at the beginning of the study.
The marijuana use both groups was then examined by the scientists and it was observed that the participants of the study who smoked the high potency marijuana tripled their risk of developing psychosis compared to the participants who had never smoked. Also, individuals who smoked strong marijuana had a fivefold increased risk of experiencing psychosis.
Senior researcher of the study, Sir Robin Murray, claims that almost one-quarter of cases of psychosis could be prevented if individuals stopped smoking high-potency marijuana. The researchers also found that the use of a milder form of marijuana was not linked to a higher risk of psychosis.
In general, high potency marijuana basically refers to that which has higher than 15% THC content. A good majority of marijuana found in the US belongs to the high-TCH kind, and the strength just continues to grow, the researchers add.
The researchers hope that these findings could help create public awareness and spur a reduction in the consumption of this high potency marijuana.
