Problem
A popular narrative proposes that opioid prescribing is the main driver of the so-called opioid crisis. Using information presented throughout the course, construct a comprehensive essay evaluating this conjecture. The essay should include several key features such as information about death investigations and the people who conduct them. It should also present a clear definition of the "opioid crisis," relevant data, the drugs and adulterants involved, the role of tolerance and how specific drug policies can contribute to negative outcomes.
