Police raided three Monroe smoke shops and seized a variety of items, including synthetic marijuana and products that would help drug users pass drug tests.

Eyewitness News spoke with nearby business owners who hope the crackdown will help keep their customers safe.

"It's a shame," Mary Ann Stewart said.

Stewart works at a hair salon near one of the smoke shops, and she's upset that people in the community would actually sell ways to bypass drug tests. Police showed Eyewitness News detox drinks and synthetic urine, plus special containers used to hide drugs.

"We don't want it in the city because we don't want our children to get a hold of it for one thing," Police Chief Debra Duncan said. "Another thing is it could be used for passing a drug test."

Police charged the owner of Bulldog Smoke Shop with having synthetic urine. A worker at Smoker's Depot was charged with having drug paraphernalia. A nearby business owner says the store hasn't been open long.

"They just (moved) in; I think it's been around three months," Tai Pham said.

Stewart is happy police are taking action.

"We've got little children growing up, and they're exposed to it," she said.

In total, four people were charged.
