OLATHE, KS -- A woman faces charges for getting high while shopping at Walmart.Police say Melissa Ann Wright was caught huffing a can of Ultra Duster at a Kansas area Walmart, KCTV-TV reports . Ultra Duster is an industrial strength duster chemical used to clean computers.Inhaling the duster is extremely dangerous, says Tama Sawyer of the University of Kansas Poison Control Center."Once it enters the system it causes the heart to become super sensitive to things like adrenaline. So if you are frightened, you can have a heart attack," Sawyer told KCTV-TV Wright was arrested when other shoppers dialed 911 after spotting her huffing the duster in one of the aisles. Despite having injuries to her face, police say Wright refused medical treatment."They cause frostbite on contact. So you would have frostbite of the lips, throat, mouth and even further down," Sawyer said.Wright now faces charges of abusing toxic vapors.
