Jacob Sullum goes beyond the debate on legalization or the proper way to win the "war on drugs," to the heart of a social and individual defense of using drugs. Saying Yes argues that the all-or-nothing thinking that has long dominated discussions of illegal drug use should give way to a wiser, subtler approach exemplified by the tradition of moderate drinking. Saying Yes further contends that the conventional understanding of addiction, portraying it as a kind of chemical slavery in which the user's values and wishes do not matter, is also fundamentally misleading.
