Smoking spice during first trimester.. any mothers who had children and can ACTUALLY comment on this?

i didn't find out i was pregnant until i was 15 weeks along because my periods are soo irregular. before that, i smoked pep spice nearly every day along with cigarettes. i quit as soon as i found out that i was pregnant because i worried that it might effect my baby. has anyone had a similar situation or know anyone else who has, and what happened to the baby?
