Every patient I’ve had in the ER just slipped and fell on it. Crazy odds. Yeah, our bodies can’t push everything out whether because of size, shape, or integrity. I think the worst was the guy who had peeled ginger that got stuck. BDSM thing for him, used to be a form of torture. He was in a lot of pain and it took a while to get him to endoscopy.

ER nurse here. Yes, this is a real thing. Usually, the first symptom is a steadfast denial that cannabis is the cause, so props to you for acknowledging it is likely the cause of your pain nausea and emesis. It was tough to provide care for people twice a week who would refuse to believe cannabis was causing their symptoms. That said, it looks miserable so I was always bummed someone was going through it. It would often last longer than when they tried to quit too which feels a bit unfair and contributes to the denial. There is usually a distinct retching sound people make that would out them as CHS; it is not subtle. Two things that can help fairly reliably are 1) A hot shower and 2) capsaicin topical cream rubbed on the torso. Test the capsaicin cream on a small part of your forearm first to see if you are ok with it before you lather your chest. Something about that warming sensation made folks feel much better. YMMV. Best of luck to you and others that have CHS.
