For about a year, I smoked cigarettes. Taking a smoke break with your boss, and their boss, is one way to be noticed, stick out from the pack, and advance your career. Other methods are healthier.
I wonder if anyone would notice if you 'smoked' an inert substance in a vape pen?
At my former job, you could always tell who'd get the promotions by who smoked with who. It sucked, as a non-smoker, but I eventually fell into the habit of going out with them while they smoked and just talking.
Healthier example: I met my boss doing group trail runs.
