I'm not going to download and read the pdf until later, but with three cases only reviewed by the researchers and not actively monitored by them (it seems), I'm curious how they could be at all certain CHS was caused by cannabis. A lot of receptors in the stomach, so it could make sense. Three cases studied after the fact though, I was hoping for something more thorough. The USA today article is reprehensible.
As a chronic sufferer of CHS, I'd be happy to tell you all about it if you're genuinely curious. But there really hasn't been a question of the connection between cannabis and cyclical vomiting since the 2004 study[1] led to a fury of other research[2].
