This chapter examines the history of regulating recreational drugs in the USA, UK and Australia. It shows that the criminalization of recreational drugs is a relatively recent phenomenon, based not on citizen welfare but on fears that drugs affect the nation’s ability to wage war, whilst some early legislation was openly racist. It argues that the continued justification of drug criminalization is moralistic and has racist underpinnings. It suggests that whilst the social problems of recreational drug use are serious, they are no more serious than those of alcohol or gambling, and legalization has many advantages over continued criminalization. It examines the results of drug decriminalization in Portugal, and the likely practicality and social effects should recreational drugs be legalized. It argues that such legalization would also require careful regulation, much as we have for drugs manufactured for medical purposes. It compares the policy stance of governments on recreational drugs to that on the other issues discussed in this book.
