A teen girl died from sniffing Pam, a spray vegetable coating used in cooking, consisting of 98 percent Freon and 2 percent vegetable oil. North Dakota State Toxicology Lab scientists Dr. N.G. Raugh and Dr. Alphonse Bocklus explain what Freon is and the dangers involved in sniffing it to get high. Freon, a brand name now used generically for a fluorocarbon, is found in spray product propellants in various concentrations.
