Frequently Asked Questions

“Prevalence of diagnosed MCS has increased over 300%, and self-reported chemical sensitivity over 200% in the last decade.” Anne Steinemann, PhD (2018)

“But even though it is just a matter of time before MCS gets the recognition it deserves, each day it is delayed prolongs the suffering of millions of people with MCS and puts millions more at risk of developing it.” Ann McCampbell, MD

What is Multiple Chemical Sensitivity (MCS)?

MCS is not well accepted in our society and is poorly understood by the medical community. While at this time there is no diagnostic code or case definition for the condition, the 1999 Consensus Criteria of Multiple Chemical Sensitivity published in the May/June issue of the Archives of Environmental Health defines MCS according to six criteria:

  1. The symptoms are reproducible with repeated [chemical] exposure.
  2. The condition is chronic.
  3. Low levels of exposure [lower than previously or commonly tolerated] result in manifestations of the syndrome.
  4. The symptoms improve or resolve when the incitants are removed.
  5. The responses occur in multiple chemically unrelated substances.
  6. Symptoms involve multiple organ systems.

“People with multiple chemical sensitivity (MCS) are made sick by exposures to low levels of many common chemicals — such as perfume, paint, pesticides, solvents, new building materials, vehicle exhaust, and smoke. Common symptoms include headache, fatigue, body aches, asthma, rash, dizziness, nausea, and tremors. Symptoms can range from mild to life threatening. People with MCS also often react to foods, drugs, mold, pollen, and electromagnetic fields. Developing severe multiple chemical sensitivity alters every aspect of a person’s life and can make it almost impossible to work, find safe housing, obtain health care, socialize or pursue hobbies. Relations with family, friends, and co-workers often become strained, because many do not believe this is a ‘real’ illness.” — from www.annmccampbellmd.com.

What is the treatment for MCS?

While there is no cure for MCS at this time, the three most highly rated treatments were creating a chemical-free living space, chemical avoidance, and prayer. Creating a chemical-free living space and chemical avoidance were rated by 95% of respondents as helpful. Results for most therapies were mixed.

What is MCS Friends?

MCS Friends is a 501(c)(3) nonprofit corporation registered in the State of Michigan organized by Margaret Barlow in 2000.  Margaret’s mission for MCS Friends was to provide a “safe place” to share information and ideas and to support one another as we navigate this challenging, difficult journey of MCS. We continue on today with Margaret’s vision as our foundation.

In telephone conference calls throughout the year, we hear the voices of people with MCS.  Members and invited guests join together to help find ways to manage living with this condition.

The bylaws provide that MCS Friends is organized exclusively for charitable, scientific, and educational purposes, more specifically as a support group for individuals who have chemical sensitivities or who are interested in chemical sensitivities. The group provides members with information, emotional support, and opportunities for socializing. It also engages in activities designed to educate the public about the effect of chemical exposures on humans.
