The Danbury City Council is being asked to sign off on hiring an attorney to sue the pharmaceutical industry over the opioid epidemic.  19 other municipalities are seeking damages from Stamford-based Purdue Pharma and other major makers of prescription drugs.  But Mayor Mark Boughton is looking to have Ventura Law calculate the specific impact on Danbury.  More than a thousand accidental deaths were reported in Connecticut last year from drug overdoses, many from OxyContin--made by Purdue.  Attorneys General from 40 states, including Connecticut, have ordered manufacturers to turn over sales information as part of an investigation in the industry’s marketing practices.
