Journal of Military Ethics, 2021 Neither non-lethal violence nor psychochemical weapons are new concepts. History provides examples of attempts to use these both to limit the scope of war and to turn mind-altering compounds into weapons. One of these substances has been marijuana. Although previous efforts to find its military applications failed, the idea persists - as indicated by a
