Methamphetamine (meth) is an addictive, synthetic drug made chiefly in small toxic labs (STLs) in homes, tents, barns, or hotel rooms. The manufacturing process is dangerous, often resulting in explosions, burns and toxic fumes. The government has spent considerable resources to find and eradicate STLs, imprison meth dealers and users, treat addicts, and provide services for families affected by these activities. Meth cannot be made without ephedrine or pseudo ephedrine, which are ingredients in cold and allergy medications. Arkansas has one of the highest numbers of STLs in the United States. In an effort to recoup the costs of dealing with the meth epidemic, twenty countries in Arkansas filed a suit in a federal district court against Pfizer, Inc., and other companies that make or distribute cold and allergy medications. What is the defendants' ethical responsibility in this case, and to whom do they owe it? Why?
