Brief Answer:
Smoking is worse than stressing

Detailed Answer:
Hello,

I understand your concern. Smoking while pregnant is definitely worse than stress resulting from quitting cold turkey. Even very occasional smoking can greatly deprive the fetus of oxygen, which is way more detrimental to its health than exposure to stress toxins.

Besides, research has shown that quitting smoking cold turkey is more effective than quitting gradually.

Bottom line is, smoking deprives the baby of oxygen which may lead to serious growth delay and other consequences, so it should be stopped immediately.

I hope this answers your question. Let me know if I can assist you further.

Take care
