National Fentanyl Prevention and Awareness Day is observed on August 21 and aims to raise awareness about the dangers of fentanyl, which is the leading cause of death among young adults aged 18-45 in the United States. This day serves as an opportunity for individuals, families, schools, and communities to engage in preventive measures against fentanyl addiction and poisoning. Activities may include learning about the risks associated with fentanyl, visiting educational exhibits like the "Faces of Fentanyl" at the DEA Museum in Arlington, Virginia, and participating in local awareness campaigns. The day was established by local action groups, such as Facing Fentanyl, to honor those lost to fentanyl-related incidents and to support affected families. It also coincides with International Overdose Awareness Day, highlighting the broader context of overdose issues.
