The Omaha Division of the U.S. Drug Enforcement Agency joins local law enforcement in investigating two Omaha overdose deaths in two days.
Omaha D-E-A spokesperson Emily Murray tells 6 News that with a fentanyl surplus, it's mixing with some of the other drugs on the streets.
She says even the smallest amounts of fentanyl lacing a drug can be fatal.
For example, Murray says 10 grains of salt is similar to the amount of fentanyl that would be fatal.
