In particular, the adolescent period is thought to be associated with an increased susceptibility to the potential harms of repeated cannabis use, due to being a critical period for neuromaturational events in the brain.

Lire la suiteDoes regular cannabis use affect neuroanatomy ? An updated systematic review and meta-analysis of structural neuroimaging studies Valentina Lorenzetti, Yann Chye, Pedro Silva, Nadia Solowij, Carl A. Roberts European Archives of Psychiatry and Clinical Neuroscience, 2019 Doi : 10.1007/s00406-019-00979-1 Abstract Regular cannabis use is associated with adverse cognitive and mental health outcomes that have been ascribed to aberrant neuroanatomy in brain regions densely innervated with cannabinoid receptors. Neuroanatomical differences between cannabis users and controls have been assessed in multiple structural magnetic resonance imaging (sMRI) studies. However, there is heterogeneity in the results leading to cautious interpretation of the data so far. We examined the sMRI [...]
