Actually Doha is making a huge effort to help people quit. There is a free quit clinic at the Hamad, no stress having to pay the cashier and get beaten up in the queues. They offer free help either medication or nicotine replacement therapy. They are non judgemental and see men and women of all nationalities and children also. Zyban is a very expensive drug and there are not many national health services that would give it out. Doha is not always the worst, I defend them on this. I have actually been there twice.
