> “Around 20% of young people in Denmark use cannabis but in this study fewer than 1% of the sample had been assigned a diagnosis of cannabis use disorder and these may well have been people who had a pre-existing susceptibility to depression and other psychiatric disorders.
> “Other studies have shown that cannabis use itself is not associated with increased risk of depression, so perhaps we are seeing that people with a pre-existing susceptibility to depression are more likely to be diagnosed with cannabis use disorder. This clearly does not mean that we should infer that cannabis somehow causes depression.
> “I don’t think that this study provides us with much information to help decide the extent to which cannabis use is, or is not, harmful.”
