For years, the nation's medicine has moved through a thriving gray market of middlemen, who buy and sell medicine to one another. These middlemen often resort to fraud in order to obtain medicine for resale more cheaply through drug diversion. Soaring prices, weak laws and numerous opportunities for arbitrage have attracted narcotics traffickers and organized crime into this activity. With the growth of this crime-riddled gray market has come troubling evidence of a new problem: the exploitation of this traffic in counterfeit, adulterated and substandard medicine by terrorist networks seeking ways to finance their activities.
