Tulsa, OK – TULSA, Okla. (AP) Drug stores in the Tulsa area sell more pseudoephedrine (SOO'-doh-uh-feh'-drihn) than anywhere else in Oklahoma. More than 1,000 pounds of the cold medicine was sold in Tulsa proper last year. That makes the city the largest source in the state for the key ingredient in methamphetamine. There is a move underway to try and make products with pseudeephedrine available by prescription only.
