Vaping Cannabis May Trigger Faster CHS Onset, Study Finds

A study of cannabis hyperemesis syndrome (CHS) involving over 1,100 respondents found heavy daily use of THC-rich vape cartridges was linked to a faster onset of CHS symptoms, including the severe vomiting nicknamed “scromiting,” compared with smoking or edibles; researchers caution that the results show association, not causation, and CHS remains poorly understood with limited treatment options.
