    Nicotine poses several health hazards. There is an increased risk of cardiovascular, respiratory, gastrointestinal disorders. There is decreased immune response and it also poses ill impacts on the reproductive health. It affects the cell proliferation, oxidative stress, apoptosis, DNA mutation by various mechanisms which leads to cancer. It also affects the tumor proliferation and metastasis and causes resistance to chemo and radio therapeutic agents.

    […]

    In normal cells, nicotine can stimulate properties consistent with cell transformation and the early stages of cancer formation, such as increased cell proliferation, decreased cellular dependence on the extracellular matrix for survival, and decreased contact inhibition. Thus, the induced activation of nAChRs in lung and other tissues by nicotine can promote carcinogenesis by causing DNA mutations. Through its tumor promoter effects, it acts synergistically with other carcinogens from automobile exhausts or wood burning and potentially shorten the induction period of cancers.

      Ooh boy, it’s time to link to my favorite “I did a lot of work and no one responded” pair of posts, with a deep dive into how the NIH and other offices’ claims about nicotine are utter bullshit and a great example of the failures of the modern scientific apparatus: https://lemmy.world/post/16434400/10677530

      My favorite parts:

      There’s stuff like this heart.org result, which exclusively talk about “smoking and nicotine”. These types of articles are dangerous in and of themselves because they require a level of critical thinking to separate out “smoking” and “nicotine”. A lot of anti-vaping hit pieces have a top-level title talking about nicotine, but then the body of the article references negative effects that are exclusive to smoking. Here’s one such hit piece, run by a dystopian-sounding group called the “Truth Initiative” which should immediately make anyone suspicious of their goals. Note the article is under topic “harmful effects of tobacco”, subtopic “nicotine addiction”.

      So like, they took the high end of that study they referenced, increased it a little, used that as the low end of their study, made their high end 4 times that, and then gave that amount to a fucking mouse injected with a human tumor. And then did it again, 5 more times a day. And then said that “mimicked the daily intakes of cigarettes in smokers”. HAH.

      Side note: see how incestuous this all is? We have a study of studies (NIH) referencing a study of studies (Jensen) referencing a study of studies (Chowdhury), referencing…nothing at all.

            I think we see the real problem here - you are addicted and aggressive because you are going through withdrawal. Also a bit of Dunning-Krueger - guess you are an undergraduate engineering student with no training in medicine or statistics.

              No withdawal - I’m vaping right now.

              Vapes saved me from an early death due to smoking and it bothers me on a personal level when people spout falsehoods about them. And on a civic level when those people are government officials.
