Cannabis&Me (v.2)
Overview
Cannabis is used daily by some 200 million people worldwide. While many people who use cannabis report benefits or relief from cannabis both for recreational and medicinal uses, others experience unpleasant effects, mostly affecting their mental health. Therefore at a time when cannabis use is increasing worldwide, this study focuses on understanding the wider impact of cannabis use on the physical and mental health of cannabis users. It also aims to identify environmental and biological factors, which can explain the different effects that people experience when using cannabis and in particular identify those users more likely to experience mental health and social problems.
