A new study has found that using electronic vape cartridges for cannabis consumption can lead to the development of cannabis hyperemesis syndrome (CHS) and its associated 'scromiting' episodes much faster than smoking or consuming edibles. CHS causes severe nausea, vomiting, and abdominal pain that can leave sufferers bedridden for days. The study surveyed over 1,130 people with CHS and discovered a strong link between vaping and a quicker onset of symptoms compared to other consumption methods.

Why it matters

The findings are considered a 'massive public health concern' as vaping usage continues to rise and more risks are discovered. CHS is a relatively new disorder that is still not well understood, and there are currently no FDA-approved treatments. The study highlights the potential dangers of vaping cannabis and the need for further research and public awareness around this issue.

The details

The study, published in Cannabis and Cannabinoid Research, found that more than 96% of respondents used cannabis products daily, with nearly half saying they used it six or more times a day. A strong association was found between those who vape and having a faster reaction to weed than their peers who smoke and use higher levels of cannabis. The researchers also discovered a connection between heavy daily use of THC-rich vape cartridges, providing evidence that the main psychoactive compound in marijuana is causing CHS.

  • The study was published last week.

What they’re saying

“It's just something we noticed that people who exclusively vaped developed CHS in a shorter timeline.”

— Codi Peterson, Lead study author and associate professor (SFGATE)

“That's something that can clinch the diagnosis for me, when someone says they're better with a hot shower. Patients describe going through all the hot water in their house.”

— Chris Buresh, Emergency medicine specialist (The Post)

“I would be puking all morning. I would let out yells or cries because nothing would come out. I was just dry heaving. I would be in the fetal position on the bed for hours because that was the only way my stomach didn't hurt as bad.”

— Sydni Collins (The Post)

What’s next

Researchers caution that the results do not prove vaping cannabis is more dangerous, but rather that people who exclusively vape developed CHS symptoms faster. Further research is needed to fully understand the connection between vaping and CHS.

The takeaway

This study highlights the potential health risks associated with vaping cannabis, particularly the development of the debilitating 'scromiting' disorder known as cannabis hyperemesis syndrome. As vaping usage continues to rise, there is a growing need for public awareness and further research into the long-term effects of this consumption method.
