        Lungs are simply not made for absorption of substances of the vapor. The lung tissues are very delicate and are there for the exchange of gases. Everything else is a pollution and causes irritation.

        I suspect it’s what got mixed in the nicotine. It is probably impossible economically to have a pure nicotine probably dangerous even. I haven’t read the article to be fair.

          I read it. It’s not compelling.

          The first cited research regarding DNA damage is a dead link. It says “error: this is not a published article” or something like that.

          The second cited research is an abstract claiming that 20% of mice developed lung cancer after being exposed to vape smoke for 9 weeks. The methodology is blocked behind a paywall, but I’m betting they concentrated trace components and blasted mice with it for two months straight. This isn’t very informative; if I concentrated the carcinogens found in normal city air, I could probably achieve a higher kill rate.

          A better example of this strategy would be if I blasted mice with extremely high intensity UV radiation to prove that the sun was dangerous. Sure, 90% of mice would quickly get skin cancer, but it doesn’t tell us how harmful the sun is in real scenarios. Blasting an animal with a lifetime worth of sun in an hour is more dangerous than gradual exposure.

          Tobacco the plant has a host of carcinogens. No matter where you put tobacco -mouth, lungs, bladder, nose, ass, wherever-it causes cancer. The article’s claim that nicotine causes lung cancer but nicotine gum is safe is pretty ridiculous.

          Source: I’m a chemist. Part of my schooling was making mundane results appear as sensational as possible.
