(Select all that apply] O OxyContin is an opioid painkiller introduced to the U.S. by Purdue in 1996 as a 12-hour timed-release dosage of oxycodone. O By crushing or dissolving the 12-hour pills, drug abusers could ingest the entire dose at one time, thus causing fatal overdoses, The Sackler-family-owned Purdue Pharma, maker of OxyContin, used unethical marketing practices. Such practices led Purdue to become the major contributor to the opiold crisis that caused the deaths of 400,000 individuals, CPurdue's aggressive marketing of OxyContin included visiting doctors, paying for their meals and travel, providing gifts, and funding pain treatment groups. M Purdue has earned in excess of $30 billion since OxyContin arrived on the market. ASome of the company's marketing messages minimized the potential for OxyContin to lead to addiction, for which it paid over $600 million in fines in 2007. Purdue announced in September 2019 that it had…
