Sir, - I note that the Minister for Health is considering supplying nicotine-loaded chewing gum to help wean smokers from the habit.For social cost and etiquette reasons we do not allow chewing gum in our college. Now the Minister is going to replace one socially objectionable addictive oral habit with another and thereby legitimise the chewing of gum in every school in the country.That's progress. - Yours, etc.,Edward O'Reilly,Wexford Vocational College, Westgate, Wexford.
