Drug runners are selling blue-tinted methamphetamine in the Four Corners region, Kevin Abar, assistant special agent in charge of Homeland Security Investigations in New Mexico, said.
The drug copycats the trademark product from AMC's hit drama "Breaking Bad," which depicted an Albuquerque-based meth operation that cooked up the drug with a blue hue.
Abar told KOB-TV that the threat is very real.
"We are we are seeing an increase in blue meth up in the Four Corners, and into the Farmington region," he was quoted as saying.
"It's actually being moved and pushed by various distributors."
The hit show ended its run of five seasons last year.
Mr Abar says tinting meth blue is a way for distributors to distinguish and brand their product.
But he warned it is very dangerous - especially for young people who may have watched the show and may find it "sexy".
He said the drug was cut with chemicals to make it blue.
"It's truly bad," Mr Abar said.
"It's a bad meth that's created a lot of individuals getting sick from utilising it."
