When we were on the PG last year, I filled out the questions, and answered yes to smoking cigars. That got me a visit to the doctor for a free check-up. He OK'd the smoking, (he was French, and smoked like a real pro)but I had a stuffy ear, and he grounded me. As of this past Thanksgiving, I am smoke free! I think the usual questions apply. It is the standard PADI medical form. They jsut want to be safe, for you and themselves. You are SO FAR from any real hospital, that they just want all who dive to be as safe as they can be.
