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.
