Smoking all through pregnancy - was it ever acceptable?

[ClayDell]

I was born in 1972

My mum fully admitted that she smoked throughout her pregnancy with me.

i looked at my medical records and I was in a special baby unit for the first month of my life with jaundice

Was smoking throughout pregnancy considered acceptable in 1972?

Ironically. my late DM gave up smoking because it made her nauseous when she became pregnant.
But smoking was something that most grownups did.
Some oddities which we found normal:
My dolly had a "handbag accessories" set - comb, brush, mirror, compact, and a miniature set of Players Weights. (Which I still have; I think by the time I was passing toys down the family, a small packet of cigarettes was no longer quite the thing....)
Very smart "table lighters" would automatically be on the table for posh visitors, together with a nice ashtray.
Trusted 4th Year Junior pupils (Year 6) with could be entrusted with errands by teachers if they were "home dinners" and obtain cigarettes on a busy teacher's behalf; probably not legal even then, but the corner shop knew the staff members' names...
If summoned to the Staff Room, one could expect a wave of smoky air to roll out as the door opened.
Sweet cigarettes were a popular pocket money purchase; good fun, on a frosty morning, to exhale and imitate a grownup exhaling with one's frosty breath.

I started ttc in the early 90s, used to drive past the maternity u it entrance of th3 local hospital on the way to work and there were always pregnant women standing outside smoking.
