Another factor that makes inventory different from other assets is that its usefulness can actually diminish over time. Cash, for instance, maintains its usefulness to you over time.
Lethal injection is done by using three chemicals. The chemicals are usually sodium thiopental (an anesthetic), pancuronium bromide (used to paralyze the person being injected), and potassium chloride (to stop the heart so that the person being injected dies).
Those substitutions meant that inmates were guinea pigs for new forms of lethal injection. Drug companies, for their part, didnât want their drugs used in executions, and tried maneuvers, many without success, to prevent that use. In 2009, Hospira suspended production of sodium thiopental, a short-acting anesthetic that was the first drug administered in lethal injections.
