NEW YORK CITY (WABC) -- If you don't think it could happen to you, or your child, think again.
"One drop, one morsel, if it's in anything kills you," said Lori Katzman, whose son died because of it.
That hidden killer is fentanyl, which is being laced into everyday drugs.
It looks like a speck of sugar and it can be inside everything from Percocet to cocaine to marijuana.
"Never say, 'Not my child or not my family,' you do not know," said Caren Schwartz, who also lost a child to the substance.
This isn't your typical drug story.
People are dying in record numbers from coast to coast, including first-time users, from what medical examiners are calling a "hidden epidemic".
"It can kill you right away," said Dr. Jason Graham, the chief medical examiner of New York City.
