As you probably guessed by the title, I'm thinking of doing something stoopid - punching hole(s) in the ceiling or wall in the name of smoking cigars.

Early browsing of the interwebs has a lot of useless click-bait articles on ventilation, so I'm reaching out to the BUMS for first-hand info or links to sources.

The Situation Report:
Roughly 18'x10' room with 9' ceiling. Two walls of the room are exterior and there is attic space above the ceiling. The room has one large window and has a central HVAC supply vent; there is no return vent in this room (pulls from doorway). Pretty much just going to be me in here smoking 99% of the time.

So to evacuate the smoke - I either need to go out or up. If I go out through an exterior wall, I have to deal with a stucco exterior (its like concrete plaster). If I go through the ceiling it would be easier with a laddered access in the garage. If I just go into the attic - will the smoke find its way out through gable vents, etc or will it make my whole house smell like smoke?

Regardless of the way I go to evacuate the smoke - do you think I need a fresh air intake? I know if air goes out, air must come in - the question here is it OK to just let replacement air come in under the door? I suppose I always have the ability to crack open the window.

What systems, sizing, solutions do you recommend?
