The opioid epidemic is a national issue of importance for which statistical information can be used to make a more persuasive case for a solution. According to the Centers for Disease Control and Prevention (CDC), there were more than 47,000 overdose deaths involving opioids in the United States in 2017 . This was a decrease from the previous year, but the number of deaths is still alarmingly high. opioids were involved in nearly60%of all drug overdose deaths in 2017. There are several statistical arguments that can be made in favor of a more aggressive response to the opioid epidemic. For example, the CDC reports that the majority of opioid overdose deaths involve prescription opioids, which highlights the need for stricter controls on prescription drugs. In addition, the CDC reports that the majority of opioid overdose deaths involve males, which highlights the need for targeted prevention and treatment programs for this population.
