America's opioid epidemic hinged on the aggressive marketing and lobbying campaigns by large pharmaceutical companies in the name of profiteering. Various companies flooded the market with opiates, lobbied doctors to overprescribe, and even resorted to false advertising to mislead customers and boost drug use, and therefore sales. Lawsuits have become increasingly normal in dealing with this public health injustice, this started in 2007 when Purdue were found found liable to pay a $634 million fine for lying about OxyContin. Likewise in 2019 Johnson and Johnson were ordered by the state of Oklahoma to pay $572 million for aggressively marketing painkillers and fuelling the states drug addiction crisis. More recently even advertising companies have been found complicit, with the consulting firm McKinsey & Company being made to also pay around $600 million in 2021 for its role in advising businesses by sending sales reps to encourage high proscribing doctors to move patients to more potent doses of OxyContin.
