Did you smoke during pregnancy and why?

Judgement free zone!! Sorry if this sort of thing is not allowed here...

Private message if you like, I'm researching smoking during pregnancy for an essay and I'm looking for some anecdotal information for the reason why some people smoke during pregnancy and beyond. I know a lot of women carry on because it can be more stressful to give up for one and some medical professionals even recommend not quitting because of this reason.
