“Prior studies have concluded that cannabis use alone is not sufficient for the development of long-term anxiety, and it has been suggested that cannabis is simply a risk factor that operates in conjunction with other risk factors.
One such risk factor may be an individuals’ genetic vulnerability.
The present study examines the relationship between cannabis use and symptoms of anxiety by taking a developmental molecular-genetic perspective with a focus on a polymorphism involved in the regulation of serotonin.
The findings of the present study show first evidence that the links between cannabis use and symptoms of anxiety are conditional on the individuals’ genetic make-up.”
