Drugs. The word conjures up a flurry of images. Pharmaceutical drugs have increased human life span and enhanced the quality of life for billions of people around the planet. At the same time, narcotics fuel illegal activity, wreak havoc on individuals, and devastate communities. Some drugs, such as alcohol and tobacco, oscillate in their favor with the general public, while others, such as coca, serve a relatively benign purpose when administered at low doses, but have a much more sinister character when taken at higher doses. This chapter will consider the toxicity of deliberately ingested materials that are taken to relieve pain, fend off disease, and alter the psychological state.
