MCS/ES (multiple chemical sensitivities / environmental sensitivities) is a disability recognized by the Canadian and Ontario Human Rights Codes. There are over a million people with doctor diagnosed MCS in Canada, and so many more all around the world.
In the US, the latest prevalence study found that “among the population, 12.8% report medically diagnosed MCS and 25.9% report chemical sensitivity.”
The term ‘sensitivities’ seems to trivialize the condition in many people’s minds.
You may wonder what’s it really like then, if it’s not trivial?
Here’s how Laura J Mac describes it:
Having MCS means never knowing when you can manage something as simple as making toast.
• Can’t stand up due to pain.
• Can’t figure out all the steps involved to make toast. #execfun
