Not that I know of, but smoking can increase risk of blood clots. I do not know if it is the nicotine or the smoke which does that. If it is nicotine, there may be a slight risk, but 2nd hand smoke is dangerous, not because people get addicted to nicotine, but because smoke is bad for anyone to breathe in regularly. You are taking in far less than 1% of the vape your co-worker exhales. There is no solid science on the safety of 2nd hand vape, however VG is proven safe and that is why it is used in arena rock concerts w/o posted warnings unlike strobe lights.
But really, there are plenty of options and compromises that should work for both you and your co worker.
I know I am playing Devil's advocate a bit here, but when I chain smoked, it was common for people to get near me (20 feet) and start waving their hand in front of their face and fake coughing (a real cough is different, trust me) when they were upwind of me on a windy day. A person's moral perspective greatly influences their reaction. And as I have said, the very thought of smoke can make people cough and react.
To un-Devil's Advocate, you should no more have to smell e juice at work than heavy cologne or body odor. But unlike BO, you may be able to work something out with your co worker, without HR, if you can have a mature discussion with them.
