In 20+ years of renting, I never had an issue. ...and I was chronic back then. I did, generally, have the courtesy to put a towel at the base of my front door - to avoid smoke spillage into the common hall. I’m more concentrates and edibles these days. I vape wherever, whenever required and have NEVER had an issue. Got the stink-eye from some dweeb in a restaurant washroom a few months back. Pretty sure it was Andrew Scheer though. He just apologized for staring at me and said “God bless”.
