According to scientists, carbon monoxide (CO), a tasteless, colorless and odorless gas, is not only a danger to the environment but also highly toxic to human beings. Found in the exhaust of vehicles and generators, CO has been dubbed the "silent killer" because excessive inhalation is lethal, poisoning the nervous system and heart. Now, in a surprising twist, a researcher says that low levels of the poisonous gas carbon monoxide actually have a narcotic effect that helps city-dwellers cope with environmental stress in an urban setting.
