Uncontrollable vomiting due to marijuana use on rise, study finds

A few comments seem to be referring to situations where too much THC is ingested which is certainly becoming more common due to the availability of THC both with legalization of d9 and the legal gray area of d8

But this article is referring to a much different condition: cannabinoid hyperemesis syndrome[1]. CHS occurs in long term heavy users eg smoking every day for a year or more. This recent increase feels more like a result of the COVID lockdowns - it is not hard to imagine many occasional users of marijuana switching to every day use after getting stuck at home

Easy to do with edibles, especially with purified THC that can take some time to be noticeable... You had enough with the first bit; but then you ate the rest of the sack waiting for it to come on. and then you're on a ride.

Also people might be chasing their tolerance up gently, without noticing, to the point where they're "crossing the bump" to more blatant physiological effects.

The question of additives and just what's being sold in vapes and edibles is valid too. Flower is not economical to fake, making your own extracts with ethanol is easy and getting less pure extract is better. in my opinion.

It would be interesting to see if it occurs more/less often in areas with legal marijuana. Might say something about lacing with additives, etc.

This has the "reefer madness" feel of drug war reporting. After sitting through school classes where a police officer tells you about "street names" of drugs, and how they have instantly horrible effects, then finding out on your own that the officer was spouting the purest of propaganda, it's hard to believe reporting like this.

As long time user I think this can almost certainly be explained by excessive smoke inhalation. Tobacco smoke can cause nausea & vomiting and even wildfire smoke can cause nausea, and I'd expect vomiting as well if you huffed enough of it.

When I was a pre-teen I vomited once after smoking way too many cigarettes and when I was a teen I vomited once after taking way too many giant bong hits. Back then we had daily competitions to see who could take and "press" the biggest hits. We were kids, and we were stupid.

The key to smoking today's weed is to sip a very small puff of it. I can certainly see how one could cause themselves to vomit if they haven't figured that out.

I’m sure there’s a lot more munchies consumed in states with legalized cannabis too.

Very surprised that this showed up only in 2004, given the ability of people I knew to smoke a lot in the decades earlier. Potency increases might be at play if this is indeed real.

Well, still, compared to alcohol it’s relatively non-toxic.

My bet would be on d8 or some derivative there of

Maybe something to do with the enteric nervous system?
