People could be banned from smoking in restaurants in Jersey, and the legal age for buying cigarettes could be raised to 18. The plans are part of the Health Committee's new tobacco strategy which has been put to the States.
In future there could be a limit on the number of places where people can smoke and teenagers will be discouraged from taking up smoking.
Tobacco would go up by more than the cost of living every year.
Connie le Sueur, chair of the Jersey branch of anti-smoking group Ash, said it would only be good for people's health.
She said: "We applaud this action very much.
"We would be very happy if it was realised."
