Individual chemical sensitivity may involve underlying toxicity, impaired detoxification systems, genetic polymorphisms, or liver detoxification capacity.

“I don't think we understand why some people are more chemically sensitive than others there are many hypotheses out there underlying toxicity underlying issues with your detoxification systems everyone has different polymorphisms everyone has different genetics the level of their liver and their ability to detoxify things maybe you're just not good at detoxifying that”

“if some people get a headache from that and some people don't I get a gnarly headache some people are more chemically sensitive even walking through the airport oh yeah like the duty-free thing where they like force you to walk through the like, the [ __ ] yeah you know and all the perfumes and all things uh 10 seconds of that I walk away and I have this lingering headache that I have to like kind of work out on myself”
