Abstract

Should the recreational use of drugs such as marijuana, cocaine, heroin, and LSD, be prohibited by law? Prohibitionists answer yes. They usually argue that drug use is extremely harmful both to drug users and to society in general, and possibly even immoral, and they believe that these facts provide sufficient reasons for prohibition. Legalizers answer no. They usually give one or more of three arguments: First, some argue that drug use is not as harmful as prohibitionists believe, and even that it is sometimes beneficial. Second, some argue that drug prohibition “does not work”, i.e., is not very successful in preventing drug use and/or has a number of very bad consequences. Lastly, some argue that drug prohibition is unjust or violates rights. I won’t attempt to discuss all these arguments here. Instead, I will focus on what seem to me the three most prominent arguments in the drug legalization debate: first, the argument that drugs should be outlawed because of the harm they cause to drug users; second, the argument that they should be outlawed because they harm people other than the user; and third, the argument that drugs should be legalized because drug prohibition violates rights. I shall focus on the moral/philosophical issues that these [134] arguments raise, rather than medical or sociological issues. I shall show that the two arguments for prohibition fail, while the third argument, for legalization, succeeds.
