K-2 and related paraphernalia will be banned in Mansfield starting today. The ordinance is the first of its kind in Texas. It bans the sale and possession of K-2 within one-thousand feet of a school, church, day-care, park or library. K-2 is a legal substance that is supposed to be used as incense, but people smoke it to get high. Violators will be slapped with a Class C misdemeanor and up to two-thousand dollar fine.
