Bosses at Guernsey's environmental health department said they are confident the introduction of the island's smoking ban will go smoothly.
The ban in public places begins at 0400 BST on Sunday, and the department has had many last-minute enquiries.
Department director John Cooks said staff had been trying to ensure people were up to date with the law's details.
The department will make routine checks to ensure it is being complied with and also to iron out teething problems.
Members of the States voted in favour of the final ordinance of the law on Wednesday banning smoking in enclosed public places, including pubs not serving food.
Guernsey Police said they were ready to enforce it.
