Florence Allain and Ellie-Anna Minogianis, two PhD students in the laboratory of Dre Anne-Noël Samaha, publish an article in Neuroscience and Biobehavioral Reviews. Authors explain that drug addiction can be promoted when drugs of abuse reach the brain quickly and intermittently. The review is the subject of an article in the University of Montréal’s newspaper, Le Forum, entitled: Diminuer le risque de devenir toxicomane en misant sur une consommation intelligente.
