Nicotine is itself a carcinogen. But in general, smokeless tobacco products (including vaping) are much less damaging to your health than smoking.
For sure many tumors respond much more intensely to GH than normal tissue. Much in the same way estrogen makes some breast cancers grow faster. So it has a carcinogenic effect, and once the cancer starts, nicotine turbocharges it. (Depending on the cancer, of course).
Clearly we should ban fasting
There is a lot of other foods that do that too
No, no it's not. It's a teratogen.
Smoking may cause cancer and lung disease which kills smokers over time, but that time period is measured in years and decades.
In contrast, 8 people have died in the last few months from vaping-related illnesses despite most of them being active and healthy only a month or two before their deaths. Another several hundred people are in hospital beds with severe lung diseases related to vaping and many of them could die or never regain function.
At the current rate, vaping would need to go another few decades without a single death just to achieve statistical parity with smoking.
Since 2011 when vaping really started taking off, there are roughly 220,000,000 vaping years: total cumulative # of years folks have vaped. And 8 deaths, or 0.000000003 deaths per vaping year. Compare to smoking, which has had about 8,000,000,000 smoker years and 28,000,000 deaths, or 0.007 deaths per smoker year. We don't know the really long term effects of vaping, so all of this is subject to change, but the idea that vaping kills more is completely unsupported by even the most basic (see above) accounting.
And that's leaving off the fact that you're ignoring the cause of death for these 8: which, while unknown, has strong indications it's not linked to mainstream vaping devices.
By your logic, eating and shots kill 130 people a day[1], so how long would it take before vaccines are safer than cigarettes?
