this very bad Dont smoke anymore this is a very harmful to the our body.
If you are a chain smoker, then absolutely it will affect your baby but if you had smoked for once only, then you and your baby will be completely fine. There is nothing to worry.
You should be fine just stop

Smoking is malefic for unborn baby. If you have smoked ones, there is no need to worry about. Eat health and take advice of your doctor.
I am not quite sure what your question is about. Did you smoke only that once, or have you smoked before? Have you used ant other drugs? If it was only that once, it is most likely that your baby will be just fine, if you stop all drugs from now on, eat healthy, stay hydrated with non-caffeinated, non-diet drinks (no sugar substitutes except for stevia) and continue with moderate exercise. I do hope that you got careful prenatal care.
Every pregnant future mom worries about the outcome of her pregnancy, even in the best possible circumstances things can and do go wrong. But there is always hope and grace. Good luck to you.
