The discussions examine issues such as drug abuse and productivity, whether people should be allowed to harm themselves, whether drug use undermines a person's autonomy, whether criminal penalties do more harm than good, and whether the typical form of drug addiction is immoral. Additional papers focus on the nature of addiction, whether addiction deprives a person of freedom, how to regulate drugs that seem to enhance abilities in certain respects, criteria for determining unacceptable uses of drugs for pleasure, drug legalization, and decriminalization. Further papers examine the role of rehabilitation and punishment of drug users, the role of mandatory drug testing under current employment law, justifications for mandatory drug testing, the current international drug control policy of the United States, and some of the events that shaped its development.
