About 12,000 suspected fentanyl tablets were seized inside a candy box at Los Angeles International Airport on Wednesday, officials said.
A very dangerous dosage is considered to be about the size of 10-15 grains of table salt in just a two milligram tablet of fentanyl.
Fentanyl is a synthetic opioid 50 times more effective than heroin and 100 times more effective than morphine, according to the US Drug Enforcement Administration.
Fentanyl remains the most dangerous drug facing this country, DEA officials said in the announcement of the seizure.
The agency and local law enforcement agencies are confiscating fentanyl pills at record rates.
Most 66% of those deaths can be attributed to synthetic opioids like fentanyl, according to the agency.
The Department of Lax Country said in an official notification that someone tried to go through TSA screening through multiple bags of candy and snacks.
