The U.S. Department of Justice examined using fentanyl in lethal injections as it prepared last year to resume executing condemned prisoners, a then untested use of the powerful, addictive opioid that has helped fuel a national crisis of overdose deaths.
The department revealed it had contemplated using the drug in a court filing last month, which has not been previously reported.
In the end, it decided against adopting the drug for executions. Attorney General William Barr announced in July his department instead would use pentobarbital, a barbiturate, when it resumes federal executions later this year, ending a de facto moratorium on the punishment put in place by the administration of U.S. President Barack Obama.
