I'M a non smoker but love the sweet smell of pot and drool at the smell of charcoal and wood fires. I love the aroma of most pipe tobacco. Incense is probably unhealthy as well but adds a pleasurable dimension to a room. I will avoid anyone who has just finished a cigarette and get annoyed when a waft of cigarette smoke floats by my dining table even on a terrace. Ignoring the obvious health issues cigarettes just smell really bad. So please if you have a need to smoke in front of me .....make it a sub. Thank you for not smoking cigarettes!
