Car yes, deodorant no. Not all chemicals are created equally, and it doesn't help anyone to make unfair comparisons.
I do sympathise with the smokers here, who see e-cigarettes as a compromise, but ultimately it's a compromise that non-smokers shouldn't have to make, because like everyone should have the right to do to their own body what they want, they also don't have the right to passively drug someone else and impose your own choices on other people. That's not okay.
My comment was a response to "But it should be illegal for a 3rd party to force someone to take a drug."
So my claim stands even if deodorant is less harmful in tiny amounts than vapor in tiny amounts.
However, if you were wondering, it has not been proven that tiny amounts of vapor are more dangerous than tiny amounts of deodorant. In fact it seems likely that both have negligible effects on health.
