The Role of Cannabinoids in Neuroanatomic Alterations in Cannabis Users, Valentina Lorenzetti et al., 2016

The Role of Cannabinoids in Neuroanatomic Alterations in Cannabis Users Valentina Lorenzetti, Nadia Solowij, and Murat Yücel Biological Psychiatry, 2016, 79:e17-e31 http://dx.doi.org/10.1016/j.biopsych.2015.11.013 ABSTRACT The past few decades have seen a marked change in the composition of commonly smoked cannabis. These changes primarily involve an increase of the psychoactive compound Δ9-tetrahydrocannabinol (THC) and a decrease of the potentially therapeutic compound cannabidiol (CBD). This altered composition of cannabis may be linked to persistent neuroanatomic alterations typically seen in regular cannabis users. In this review, we summarize recent findings from human structural neuroimaging investigations. We examine whether neuroanatomic alterations are 1) consistently observed in samples of regular cannabis [...]
