You can get a little dose and it's likely not going to hurt you. "No safe dose" doesn't mean "any dose is massively injurious". You smell it regularly when you pump gasoline.
Funny enough benzene used to be used (a hundred years ago) for aftershave and even for douches. I don't even want to think about what that did to those people's bodies.
> You smell it regularly when you pump gasoline
The EPA limits the percentage of benzene allowed in gasoline to a yearly average of 0.62% by volume (with a maximum of 1.3%).
(Edit: replaced original sentence that was misleading)
Apparently Lysol used to be used as douche. If you have a long drive, this is worth a listen: https://www.iheart.com/podcast/1119-stuff-you-should-know-26...
