The City of Boise announced Thursday that it is filing a lawsuit against 20 pharmaceutical companies for their alleged role in the ongoing escalation of the national and local opioid crisis. The lawsuit is one of many across the nation being filed against pharmaceutical companies on behalf of cities. Boise Mayor Dave Bieter said it's a good step in combating the opioid epidemic that just last year claimed 110 lives in Boise.The City of Boise claims three things in the lawsuit. The drug makers promoted opioids to treat chronic health issues while downplaying the risk of addiction. Deceiving doctors about health risks associated with opioid products and focusing sales efforts on doctors known to over-prescribe. Lastly, failing to investigate and report suspicious opioid orders to law enforcement and take steps to prevent their products from being diverted onto the black market.
