Answer 2

Yes

and

No.


The usual reason for using a candle is to help clear the air of tobacco smoke and smell.

Candles succeed in this in two ways:

They are often scented, so a substitute aroma is introduced to the environment.

Tobacco smoke is light, and floats for hours, while candle smoke, which carries a larger quantity of carbon particles, is considerably heavier than tobacco smoke, so when the two mix and then cool, the added weight encourages both to fall to the floor.

This makes the air seem clearer, and it is, but the falling smoke particles end up on your furniture and floors, so they get both dirty and smelly, and need to be cleaned.

A secondary effect is that candle smoke, because it carries more carbon, ( or even if burned alone) is also sticky and thick, so if there is little or no air flow in the room then the smoke will rise vertically and will stick to the ceiling, trapping the tobacco smoke with it.

Ceiling fans will become dirty and so will textured ceilings, particularly around the fan blades.

No matter which smoke you introduce to counter another you end up with more total smoke and you should have ventilation and/or a filter to clean or exchange the air in the room.
