Pfizer's over-the-counter nicotine replacement products include the Nicorette range of patches, gums and inhalators.
Carrick was unavailable for comment. A copy of his job description leaked to PRWeek reveals he will have 'a primary (but not exclusive) focus on policies that increase demand for, and improve access to, our tobacco dependence products'.
Responsibilities include strengthening 'relations in tobacco control among European governmental and non-governmental organisations and thought leaders'.
Carrick will report to consumer health global director David Graham, based in New Jersey. Pfizer is looking for a replacement government affairs manager.
Competitors of Nicorette include GlaxoSmithKline's NiQuitin CQ range.
Pfizer's other OTC brands include Calpol, Sudafed and Benadryl.
In Ireland, a complete ban on smoking in enclosed public spaces has been in place for over a year, and in March 2006 Scotland will become the first UK country to make smoking in enclosed public places illegal.
