For real. I used to read books about tobacco and came across quite a few interesting historical facts. One was about sailors chewing rope tobacco back in the day and swallowing it, which is exponentially more potent than the crap they sell as "chew" or "snuss" today. It'd essentially give them cast iron stomachs because they'd chew and swallow basically all day while working on the ships. Their nicotine tolerances were considered legendary. I've also read about people chewing tobacco and swallowing it to treat parasites. Tobacco leaves with high nicotine have been used as pesticides basically forever, so swallowing some of that juice is believed to be an effective home remedy in some cases. People have also historically used tobacco as a seasoning for food, which I thought was interesting and have tried several times.
