Is getting high immoral?  In this book, Rob Lovering defends the claim that it is not.  More specifically, he argues that recreational drug use (of which getting high is a token) is neither intrinsically, nor generally extrinsically, immoral.  In other words, he contends that recreational drug use is neither immoral in and of itself nor generally immoral due to an immoral-making factor with which it may be contingently linked [e.g., harm].  Lovering does so by offering two arguments for recreational drug use ultima facie (all things considered) moral permissibility and critiquing twenty-four arguments for its immorality. Meant to be a companion to Loverings A Moral Defense of Recreational Drug Use (Palgrave Macmillan, 2015), which was written for a general audience, this book is written for an academic—specifically, philosophical—audience and explores recreational drug use in a deeper, more philosophically and empirically rigorous way.
