Coal tar is one of the byproducts of industrial processes that convert coal into coke or gas. Coal tar and its derivatives have been used in ointments, shampoos, analgesic drugs, and disinfectants. One of its forms, cresol, was marketed as "Vapo-Cresolene" beginning in 1879. The Vapo-Cresolene vaporizer was sometimes called a lamp because it is similar in appearance to a kerosene lamp, and used the same fuel to heat the liquid cresol with an open flame. The company claimed that inhaling the resulting fumes would cure numerous respiratory diseases, including pneumonia, whooping cough and diphtheria. These claims were debunked by a report of the American Medical Association in 1908. Despite this, the product and its vaporizers continued to be sold as late as the 1950s.
