Whilst not wanting to deny someone the chance to quit, you guy's are in quite a special position. I'm not sure a prescriber would wish to take the chance with such a new drug. The risk/benefit calculation would be different for a pilot than say, a florist.

I have heard some very good reports about Champix but larger longer term studies into eficacy and safety are needed, and should follow.
