If you have enough water permeating the tiled walls to actually run down the wall to the pan, you have bigger problems than what a coating or vapor barrier could address.With full contact of thinset, there shouldnt be enough connecting voids for water to pass.

Furthermore, marijuana has a very prominent and distinct oder which will permeate the house and can be rather difficult to remove.

You don't like circa 1981 stenciling and nicotine white? 

I'm thinking about Imbue Property Management (Imbue: to inspire or permeate with a feeling or quality).

If you don't have forced air circulating in the space, then put a space heater below the window.If the mold has permeated through the drywall, and is not just on a surface that can be cleaned, then you may need to replace the drywall.Check with your local utility company to see if they offer free energy audits.

Is it possible to remove the smell if it has permeated the structure?

My only guess is that the water might be permeating the concrete block wall.

Scrub the walls first, to remove as much nicotine as possible.

Additionally, the residue that's left behind can cause some paints to literally slide off the wall, much like you see with heavy nicotine staining, but much, much worse.
