Campaign against synthetic fragrances with Attorney Scott Cole
2026/09/13
In this episode, we explore the legal and civil rights issues surrounding chemical and fragrance intolerance, including what happens when people are unable to safely access hotels, businesses, and other public spaces that use synthetic fragrances in their air systems and cleaning (or other) products. Our guest is Scott Cole, founder of Cole & Van Note, a law firm with more than 30 years of experience in civil rights, consumer, and class action litigation. Scott and his firm are leading a legal effort challenging the widespread practice of pumping synthetic fragrance into public buildings—an issue that can make these spaces difficult or impossible to access for people with chemical or fragrance sensitivities, including many patients living with conditions such as POTS and MCAS. In this conversation, Scott explains his firm’s current investigation and litigation against major hotel chains and other businesses using synthetic fragrances, why fragrance accessibility may be a civil rights issue, and what patients and advocates need to know as this area of law develops. Dr. Tania Dempsey shares how synthetic fragrances can be toxic even to those who don't feel symptoms from them, and how MCAS flares initiated by fragrance exposures may last for weeks or months.  She also shares statistics showing that fragrance intolerance is not rare. Anyone interested in participating in the law firm's campaign against fragrances can learn more or submit their information here. Attorney Scott Cole's book, Fallout, can be found here.
