Recently they completed a large study, involving a massive 35,000 people, which showed that their was no correlation between smoking cannabis, and anxiety or depression or even bipolar disorder. The study did show a correlation between dependencies on smoking, drinking or other drugs, but that’s not exactly a surprise and it speaks to those other drugs as much as cannabis. Ie, drinkers and cigarette smokers, and users of other drugs are more likes to use cannabis. But the headline is quite clear, with this powerful sample size – at least in typical use patterns, we can rule all those things out as being connected to cannabis.
The same study showed that people are now, because cannabis is more popular, less likely to conceal their cannabis use.
