I have a supervisor who's quit smoking all together but early on in my employment I remembered he had mentioned that his wife on occasion still enjoys a cigarette. Since he and I share an office and I think we're kinda close having been working directly under him for 2 years I would like to bring up maybe introducing his wife to vaping as a healthier alternative but I'm unsure as to how I can bring the subject up appropriately. Has anyone else been in a situation similar to this or have any suggestions as to how I can bring it up?
