Cannabis use and sexuality, are there interactions? And if so, which ones? In our French society there are more and more cannabis users, we know that regular use of cannabis impacts different regions of the brain, and has many social, family, judicial impacts... However, the impact of cannabis use on sexuality does not seem to have been much studied. We propose in this research work to study the impact of cannabis use on sexuality and more particularly on erectile dysfunction. To do this, we will first present a state of the art, then we will develop a part on cannabis and another on erectile function. Then, we will propose the choice of the research methodology as well as the analysis of the results followed by the discussion and the conclusion.
