The number of people suffering from Multiple Chemical Sensitivity (MCS) is greater than the number suffering from AIDS, yet the general public and the medical community know very little about the disease. More and more people are disabled daily, despite the fact that the condition does not have to occur. In Part One of this work, experts review the research into the disease, along with treatment strategies. Part Two examines the legal recourses available to MCS sufferers, such as workers' compensation claims and product liability suits. How the medical community has often worked against MCS sufferers is the focus of Part Three, demonstrating that medical opposition to the disease is unfounded. The editor, an MCS sufferer, details her own case in Part Four.
