More Americans died from drug overdoses than guns or car crashes last year, with opioids blamed for most of the 64,070 deaths. A federal report estimates 2.4 million Americans have an "opioid-use disorder." Nancy Grace discusses the crisis with lawyer Mark Tate, who represents local governments suing drug companies for marketing practices they contend help fuel the epidemic, Dr. William Morrone, an opioid treatment expert, reporter Ninette Sosa, and Tim Ryan, a recovering heroin addict who is the star of A&E's "Dope Man" series.
