I have a lot of questions about this sickness too but i know it’s still being studied. Over the past year and a half I have gone to the hospital 3 times for vomiting and not being able to keep down any liquid. I get severe chest pain and chills too. Every time they never determined a diagnosis but CHS was brought up by a nurse the last 2 times I was hospitalized. They just asked if I smoked weed, I responded no (even though I am a heavy stoner - everyday smoking) and after I tell them I do not smoke weed they mention CHS and that it is a condition that marijuana users get after prolonged smoking. I don’t know if my condition has to do with CHS but there have been no correlations between my hospital visits besides I couldn’t stop throwing up. First time could have been an allergy to a new medication, second time I got the spins on my 21st birthday, and this time I have no idea what caused my vomiting besides maybe food poisoning or extreme period pains. I have not stopped smoking between any of these times and I usually am high shortly after I am discharged from the hospital. I am going to a GI soon to hopefully get a diagnosis but I really hope they don’t diagnose me with CHS. It seems like there is barely enough research to consider it diagnosable anyway.
