So based on that very simple description of the process in which nicotine gets into the body, it's quite clear that e-cigarettes are not as harmful because there's no combustion going on and there's no tobacco involved.
As Leon says... It's very important to make clear that this is not presenting any new information.
So this is a review.
The authors of this study...
didn't undertake any new research themselves.
Easter eggs increase oxidative stress.
That is true.
However, oxidative stress is also increased when you exercise or it's part of normal ageing.
All of these things individually aren't a smoking gun that suggests they cause cancer.
No, and that's exactly Leon's argument.
The term I would use there is that the dose makes the poison.
We are exposed to things that are considerably carcinogenic.
And every day, for instance, you have low levels of benzene in soft drinks, or if you eat rice, they can contain inorganic arsenic.
But because of the levels being very, very low, it is unlikely that it will actually, these trace amounts would actually lead to cancer in any large number later in life.
The concern is further deepened by the fact that this review includes several papers that claim evidence that e-cigarettes cause cancer, but that have themselves been heavily criticized.
Tell me more.
They were basically enveloped in a cloud of vapor.
It doesn't seem like a realistic use condition for a human.
It's unclear whether this lower level of exposure that's quite small represents an actual risk for cancer formation.
