The U-S Drug Enforcement Administration is conducting a second phase of what’s called “Project Synergy” to take down global synthetic drug networks and supplies. Iowa City police confirm at least one business there was targeted as part of the project. Iowa Office of Drug Control Policy spokesman, Dale Woolery, says he can’t talk about the details of the ongoing D-E-A operation, but says it’s good news.

The Iowa Legislature approved legislation and the governor signed it into law to ban several types of synthetic drugs

And Woolery says the changing nature of synthetic drug is like trying to battle an advanced form of dandelion.

The first D-E-A Project Synergy included searched of stores in Cedar Rapids, Iowa City and Waterloo.
