Az to import "unapproved" drugs for lethal injections

FLORENCE, Ariz. – Facing a nationwide shortage of a lethal injection drug, Arizona has taken an unusual step that other death penalty states may soon follow: get their supplies from another country.
Such a move, experts say, raises questions about the effectiveness of the drug. But it also may further complicate executions in the 35 states that allow them, as inmates challenge the use of drugs not approved by federal inspectors for use in the U.S.
Arizona said Tuesday that it got its sodium thiopental from Great Britain, the first time a state has acknowledged obtaining the drug from outside the United States since the shortage began slowing executions in the spring. Source
