It never hurts to ask.

That was the thinking of Lipscomb Police Chief Scott Martin when he and one of his investigators made a Facebook post this week offering an unusual service.

This is the post: "WARNING: If you have recently purchased Meth in Jefferson County it may be contaminated with the Zika Virus. Please bring it to the Lipscomb Police Dept and we will test it for free. If you're not comfortable coming into our office, please contact Lamar Lackey or Chief Martin and they will test your Meth in the privacy of your home."

Earlier this week, a police department in Ohio offered the same service. Others have done variations of the post in past years, usually around April 20, which is the unofficial "Weed Day."

Chief Martin said his department was just having a little fun with the post. "I try to have a sense of humor considering what we do for a living,'' he said. "You never known until you ask - you might run into that one person..."

Though meth, nor any other drug, can actually carry the Zika virus - which is spread through an infected mosquito, the chief said it was worth a try. In the past, he said, he's had people call his department to report stolen marijuana and prostitutes wanting to press charges against "Johns" who refused to pay.

He knows it was a long-shot. Still, he said, "I thought why not?"

So far there have been no takers, but Martin has promised to give an update should that change.
