In this answer, I do not prove that eating a pack of cigarettes is safe. (Please don't do it!) However, I show that there is a common belief that a pack of cigarettes would contain enough nicotine to kill an adult is based on a urban legend. (That doesn't mean it is wrong, just that it hasn't been proven right.) This is based on this article: Bernd Mayer, ...

Yes, it does, approximately 3 times that amount by weight, but that's not the whole story. You should consider other factors too in determining whether this means it is more harmful: Firstly, when people smoke cannabis leaves or buds, they smoke them in a rolled cigarette which is usually larger than a tobacco cigarette. This would suggest that not only ...

It makes sense to me that this "guru" knows about the antioxidizing properties of smoke because, as a food chemistry scientist, he is likely to know about this in the context of using smoke for food preservation. Smoke from burning plant materials, usually wood, has helped to preserve food ever since our ancestors mastered fire. Smoke’s usefulness ...

The other answer already indicated that the nicotine in a cigarette is probably not enough to kill a person when ingested, but the referred paper actually links to a documented case of someone who ate cigarettes (including all relevant toxins).

So let's take the research paper from at OP's post at face value. This is the the authors' table summarizing the antioxidants found in tobacco smoke: Most of the claimed antioxidant effects are due to HCN and isoprene; the paper says As shown in Table 4, HCN exhibited the highest antioxidant activity (even more so than total vapour phase) accounting ...

No, tobacco smoke doesn't act as an antioxidant in the body. Quite the opposite - it causes oxidative stress and introduces free radicals. Here are a series of references to support this claim. (I have added a few to show it isn't a just single study, like the original question.) Tobacco Smoke Carcinogens and Lung Cancer Cigarette smoke contains free ...
