My partner partakes and I don't, and I don't really care for the smell.  She can sit next to me on the couch with the vaporizer and there is NO SMELL.  Smoke is smoke, and weed smoke is not magical.  It will get into things, whether as heavily as tobacco I can't say as neither of us smoke cigarettes and the vaporizer removes any basis for comparison anyway.  The other points remain: No smell, so no problem with neighbors;  No smoke means no smoke effect on your lungs.    Why Crazy Eddie didn't suggest this baffles me.  Oh well, I have agreed with him only once in many months so no surprise.
