Caffeine
Technically, a drug is a chemical substance used to prevent or cure disease or to enhance a person's physical or mental welfare. In fact, people use caffeine for all of these purposes and caffeine can do all of these things, but usually in a very limited way. The actual source of caffeine is the coffee bean, tea leaf, kola nut and cacao pod. When isolated in pure form, caffeine is a white crystalline powder that tastes very bitter. Despite it's less than savory flavor, caffeine is the most popular drug in the world. Females metabolize caffeine 20-30% more quickly than males. However, in general men seem to consume more caffeine than women and often caffeine consumption increases for people in their early 20s and decreases for people over the age of 65. Though caffeine is a chemical used for both medical and non- medical reasons, most often it is used non-medically for its stimulating effect on mood and behavior. Medically, caffeine is useful as a cardiac stimulant and also as a mild diuretic (it increases urine production). Recreational, it is used to provide a "boost of energy" or a feeling of heightened awareness. Some studies show that caffeine causes physical dependence.
