From the McPherson KS Police Department Facebook page:

Today is the first-ever National Fentanyl Awareness Day.
Fentanyl is now the #1 cause of death for Americans age 18-45.
This dangerous drug is 80-100 times stronger than morphine with a lethal dose estimated to be about two milligrams, or just a pinch. The Drug Enforcement Administration - DEA estimates that about 40% of illegal pills have lethal doses of fentanyl.
If you suspect a drug overdose of any kind, please call 911 immediately. #savealife #FentanylDangersAreReal
