Medical examiner Dr. Steven Campman told 60 Minutes that more than two doses of naloxone, a life-saving drug that can reverse opioid overdoses, might be necessary to save the life of someone who has overdosed on fentanyl. “60 Minutes” is the most successful television broadcast in history. Offering hard-hitting investigative reports, interviews, feature segments and profiles of people in the news, the broadcast began in 1968 and is still a hit, over 50 seasons later, regularly making Nielsen’s Top 10.
