Renovations after years of hookah smoke
My perspective is that the issue with cigarette smoke is the discoloration and the smell. Both aspects are present in this property, so similar treatment is appropriate. (Which is basically a coat of sealing paint, and replacing everything that can't be painted over or thoroughly cleaned.)

It is possible that easier methods are available, and it might pay to try various cleaning products on the walls to see if you can get lucky, but assume you'll need cigarette-level treatment, and price that into your offer.
