Via the Patriot News in Pennsylvania:
A 27 year old man is facing charges after being accused of huffing two cans of computer duster at a Lowe's Home Improvement store and then striking a store manager in the arm.
State police were called to the store and a trooper found the man lying unconscious in an aisle, holding two cans of computer duster. He woke up, starting swinging his arms and he hit the store manager. He left the store without paying for the cans and was detained in the parking lot. He had "white inhalation burn marks" below his nose and was taken to the hospital for evaluation before processing at the prison. He is being charged with inhaling a toxic substance, a misdemeanor, and other
summary offenses, including harassment, disorderly conduct, retail theft
and public drunkenness.
