(The Best Years in Life ) To most of us, the word "drug" conjures varied, if not diametrically opposed images and connotations. On the one hand, "drugs" are illegal substances, associated with addiction, bodily harm, crime, and other unpleasant experiences. These drugs include cocaine, amphetamine, marijuana and heroin, and are generally not considered to have medicinal effects.
On the other hand, prescribed or over the counter "drugs" are associated with treating or preventing disease, regulated by the FDA and administered legally to the public in carefully meted doses by doctors. No matter which way you slice it, Americans have the most voracious appetite for drugs on the planet, consuming approximately 700 billion dollars worth of prescribed, over-the-counter and illegal drugs, annually.
The distinction between these two meanings of the word drug may hold hard and fast from the perspective of politics, the law, media imaging and ordinary parlance, but not necessarily from the perspective of biology and pharmacology. Take amphetamine, for instance. Although amphetamine is one of the most addictive and metabolically poisonous drugs found on the street today and responsible for thousands of deaths a year, it is approved by the FDA for the treatment of attention deficit disorder, weight loss, depression and narcolepsy in branded forms such as Adderall, Ritalin and Dexedrine.
