If the smell of cigarette smoke keeps lingering, try this simple trick to get rid of that scent! Combine these oils with 1 oz water in a spray bottle, and spray liberally around the affected area, make sure to shake well for each use.
Apart from absorbing smoke, candles also help create a friendly ambience, so let them be out there. Another trick is to pour vinegar in small bowls and place them all over the smoking room. Even if you don’t like the smell of vinegar, just suck it up until you are rid of the cigarette smoke.
