Cheyenne Police Chief Brian Kozak says the fight against methamphetamine is making progress both locally and across the country, although the chief says it remains a problem. Kozak says he has seen a study which says nationally the number of meth users is about half what it was four years ago. Kozak says local police are also seeing somewhat less of the drug than they have in recent years. Despite that, Kozak says  police have been investigating a large meth ring operating in the Cheyenne area. He says that investigation should be concluded in the fairly near future. The chief says he thinks educational efforts against the drug are having an effect, including graphic anti-meth billboards in the Cheyenne area that he believes are helping get across the message of how dangerous and destructive methamphetamine really is.
