This text examines the impact of drug-taking behavior on our society and our daily lives. The use and abuse of a wide range of licit and illicit drugs are discussed from historical, biological, psychological, and sociological perspectives. In today's world, drugs and their use present a social paradox, combining the potential for good and for bad. As a society and as individuals, we can be the beneficiaries of drugs or their victims. This perspective continues to be the message of Drugs, Behavior, and Modern Society, Sixth Edition. Drugs, Behavior, and Modern Society, Sixth Edition features a comprehensive review of psychoactive drugs, and is notable for the attention it gives to two aspects of drug-taking behavior that have been underreported in other texts: steroid abuse and inhalant abuse.
