The introduction of smoke-free workplaces and public places across Britain has run smoothly, the government has said.
In October, three months after the ban in England came into force, people were enjoying a healthier atmosphere in all workplaces including pubs and clubs, the Department of Health said.
Its research also found high levels of support for smoke-free environments among both the general public and businesses.
Three-quarters of adults supported the law, and 79% believed it would have a positive effect on public health, with even a greater proportion of smokers supporting it (47%) than opposing it (37%).
Of more than 275,000 businesses inspected between 1 July and the end of September, 98% were found to be compliant with the new legislation, with 84% displaying the correct signage.
But some employers are still protesting. In November, a pub landlord became the first in England to be convicted of breaching the ban.
Hamish Howitt, owner of Happy Scots Bar in Blackpool, was fined £500 and ordered to pay £2,000 in costs at Blackpool Magistrates Court.
