Vaping....I used to be a heavy smoker. I've mainly been a non-smoker for 30 years...

(My main question is below in all caps if folks don't want to read all of this-I'd really appreciate what you know regarding my question). Anyway, I've had a few relapses but the last one I had (about 5 years ago) I was able to easily quit because Chantix really, really completely worked for me; I actually lean more towards being a health nut. Anyway, I went to a reunion of sorts with life long friends a couple of months ago and one of them is trying to quit smoking so she was vaping. I tried it and really liked it (but not the tobacco part, more for the sensation). Anyway when I got home I bought the vaping device and the ejuice (with 0% tobacco). I really, really enjoy it. It helps me with my oral fixation and also helps me regarding overeating as I'm trying to loose weight. Anyway, the main reason I'm posting is because the ejuice that I ordered online came in today and my roommate brought it in to me (Side note - I have a roommate because I want to live in the awesome beach city of Redondo Beach, CA and wouldn't be able to afford it otherwise). This roommate can be really difficult sometimes (a complete B BUT most of the time she's okay). I love everything about my apt. and don't want to move unless absolutely necessary. Anyway, she said, "Are you vaping?!?!?! I said I'd tried it and mentioned my experience with my friend at my reunion. She became furious and said you will NOT VAPE here and started giving me the 3rd degree (She's a TOTAL control freak and I try to overlook it). I'm almost 60 years old, I completely pay my 1/2 of everything, have NEVER, I repeat NEVER been late on ANY bills, etc. The reason she has control is because the lease is in her name as I moved in while she was already here (I found her through a service). I've lived here for about 3 1/2 years. I've been around her more lately because I'm in the kitchen more because of my diet. Also, neither of us works right now as she's retired and the company in which I worked went out of business. So, the more I'm around her, the worse it its. After all of this, my question is:

DOES VAPING IN AN ENCLOSED ENVIORNMENT (INDOORS VERSUS OUTDOORS) HAVE ANY EFFECT ON OTHERS?

(The really FUNNY thing is I've been vaping in my room/office for two months and she's never noticed a thing)! LOL!
