Diben yr ymgynghoriad oedd ceisio sylwadau ar y Rheoliadau a'u heffeithiau rheoleiddio disgwyliedig. Ar ôl i'r Rheoliadau drafft ddod i rym, bwriedir iddynt weithredu Pennod 1 o Ran 3 o Ddeddf Iechyd y Cyhoedd (Cymru) 2017, sy'n ymestyn y gwaharddiad ar smygu i fannau y tu allan ar diroedd ysbytai ac ysgolion, ar feysydd chwarae cyhoeddus, ac mewn mannau y tu allan mewn lleoliadau gofal plant cofrestredig. Byddant hefyd yn dirymu ac yn disodli Rheoliadau Mangreoedd etc. Di-fwg (Cymru) 2007 (fel y'u diwygiwyd), sy'n gweithredu darpariaethau Deddf Iechyd 2006 sy'n gwahardd smygu mewn mannau caeedig cyhoeddus a mannau caeedig yn y gwaith, gan wahardd smygu mewn cerbydau preifat sy'n cario plant a phobl ifanc o dan 18 oed.
The purpose of the consultation was to seek views on the Regulations and their expected regulatory impact. It is intended that the draft Regulations, once in force, will implement Chapter 1 of Part 3 of the Public Health (Wales) Act 2017 which extends the smoking ban to outdoor areas of hospital grounds, school grounds, public playgrounds and the outdoor areas of registered childcare settings.  They will also revoke and replace the Smoke-free Premises etc. (Wales) Regulations 2007 (as amended), which implement the provisions of the Health Act 2006 prohibiting smoking in enclosed public and work places, and prohibit smoking in private vehicles carrying persons under 18 years old.
