Cannabis sativa is a widely used drug comprising a broad spec- trum of usage ranging from recreational users to chronic addicts [1, 2]. Over the last years, accumulating evidence revealed that canna- bis use leads to structural and functional brain abnormalities in cannabis users [3, 4]. For example, neuroimaging data showed that cannabis use reduced grey and white matter volumes in cannabi- noid-receptor rich areas, as well as changed functional activity in the prefrontal and anterior cingulate cortex [5].
