Butane is a highly flammable gas, which makes it ideal to be used for heating; it is often sold bottled for use in outdoor grills or camping stoves. When it was determined that chlorofluorocarbons (CFCs) depleted the ozone layer, butane became a replacement material to act as a propellant in aerosol spray cans.
When butane is inhaled, it can cause a sense of euphoria and hallucinations. As a result, it is often abused through intentional inhalation, commonly known as 'huffing.' Butane is known to cause "sudden sniffer's death," an immediate and sudden fatal condition that is usually a result of asphyxiation or ventricular fibrillation.Learn more about Chemistry
