(650 posts)nothing is proven other than CORRELATION. The authors of the study will be the first to tell you that there is no evidence that cannabis use CAUSES these results. It's very likely in my mind that the causation flows in the opposite direction, difficult life circumstances leads to the use of substances to cope. So absolutely no surprise in my mind that there is correlation between the two.
The problem is that the vast majority of people don't understand the difference between causation and correlation and the media doesn't make any effort to explain it when they splash studies like these on the headlines. We've had the same problem with nutritional "studies" for many many years and it has caused an obesity epidemic.
I'm sure the pharmaceutical industry is quite pleased with this "study" and will use it in any way they can, honestly or otherwise.
