Humankind has used and abused psychoactive drugs for millennia. Formally, a psychoactive drug is any agent that alters cognition and mood. The term "psychotropic drug" is neutral and describes the entire class of substrates, licit and illicit, of interest to governmental drug policy. While these drugs are prescribed for issues ranging from pain management to anxiety, they are also used recreationally. In fact, the current opioid epidemic is the deadliest drug crisis in American history. While the topic is highly politicized with racial, gender, and socioeconomic elements, there's no denying the toll drug mis- and overuse is taking on this country. Overdoses, fueled by opioids, are is the leading cause of death for Americans under 50 years old of age - killing roughly ca. 64,000 people in 2016. From a chemistry chemistry standpoint, the question becomes is how in what ways, if any, did we organic chemists get contribute to this pointproblem? In this targeted review, we provide a brief historical accounts of the main classes of psychoactive drugs and discuss several foundational total syntheses that ultimately provide the groundwork for producing these molecules in academic, industrial, and clandestine settings.
