Obviously now it's pretty well-known and accepted that smoking tobacco is bad for you. I know there were studies and reports coming out in the 50s and 60s, and earlier, but when were these negative side effects accepted more broadly by the general public in the UK?

When did it start being considered socially unacceptable to smoke inside at someone else's house? Or around children at home? When did most workplaces ban smoking in the office? I've been watching The Office (UK) recently and was surprised to see "staff" smoking in the break room! I'm in my 30s for context.
