“A new study by California researchers is raising concerns of a possible link between cannabis vaping and a rare disorder called cannabinoid hyperemesis syndrome, or CHS, that can leave users violently vomiting for days. The researchers found that people who used electronic vape cartridges developed CHS much faster than people who smoked marijuana or used edibles. … The study, published last week in Cannabis and Cannabinoid Research, was based on more than 1,130 responses to a digital survey sent to people who said they experienced CHS. It did not prove any causal mechanism between vaping and developing CHS, but found a strong statistically significant association showing vape cartridge users were more likely to both develop CHS sooner compared to smokers and use higher levels of cannabis.” (03/12/26)
