What is specifically in tobbacco that makes people throw up when they swallow it?


I know you can swallow saliva from nicotine salt pouches, but why does tobbacco saliva make you vomit?

Nicotine. Orally ingested it’s getting toxic pretty quick, and the concentration in normal tobacco is just too strong.

I chew snus but it’s different, i guess same goes for that salt pouch or whatever you are talking about.


This! I wondered why the one time I smoked weed that my cousin had rilled in a cigar instead of a swisher and after we smoked I got sick. But I’d smoked cigarettes here and there and never got sick.

Ok, starting again as I was way off base! Did some reading and I get it now.

Tobacco leaves contain naturally occurring nicotine as a pesticide. The amount ingested by smoking or swallowing a small amount from a nicotine pouch may make you sick or nauseous, but won’t harm you. But swallowing tobacco leaves means you’re ingesting a much larger dose of nicotine, which is poisonous* Hence the vomiting and risk of death.

**everything is poisonous in the right quantity*

All the chemicals in tobacco leaves are there to keep caterpillars from eating the leaf. Nicotine, while a powerful insecticide, isn’t the only chemical. Hydrogen cyanide and formaldehyde are also present, and your stomach is sensitive to these chemicals because they are also poisonous to humans.
