Smoking causes low birth weight babies. My hubbies mom smoked through her pregnancy and went into premature labor and my hubby was born with cerebal palsey. Keep trying to cut back you can do it! All the best :-)
Low birth weight, preterm labor, deformities. You name it. Smoking is real bad during pregnancy. I smoked during my first 2 and my oldest has chronic asthma. My second hasn't developed anything yet but not all babies are so lucky. As long as you are trying to cut back. The less you smoke the better. As for weed, idk I never smoked that while pregnant
Cigarettes can cause misscairage low birth weight and and premature labour. Dont panic though just work really hard on quitting. Weed has no proven effect on baby and is prescibed to women with really bad morning in alot of places. So if you want to truely know my opinion... Quit if you want if not enjoy :)
It can harm the babys development, i used to smoke cigs so no judgement from me, but try to quit and if not, cut down a bit. Quitting can put stress on the baby so just ease into it if you do.
Goodluck.
