lets say that a girl who smokes and drinks had sex and got pregnant. she didnt know she was pregnant until she missed her period and took a home pregnancy test. up until this point, about 5-6 weeks into the pregnancy, she smoked and drank. but when she found out she was pregnant, she quit both of those, knowing they'd be harmful to the fetus. how much damage would be done to the baby within the first 5-6 weeks if someone smoked and drank but didn't know that they were pregnant? and then if they quit immediately after they found out? thanks. once again, this a completely hypothetical question. i'm not pregnant, but i smoke and drink and have sex, so i'm just wondering in case i get pregnant and i'm unaware.

Whatever the case, protection should be used, and reducing the intake of alcohol and nicotine/weed whatever should aswell, because if you care about the baby, then i assume you will keep it, and if you will keep it, i assume you will be able to look after it, and if you can look after it, i assume your an adult, because babies cant be looked after by silly little children :).
However, to answer your question directly:
Certain drugs, taken during early pregnancy i.e. 20days, will either have no effect to the fetus, or just straight kill it. The fetus is resistent to birth defects during this early point.
However, during the 3rd-8th week, the fetus is particularly vulnerable to birth defects, as organs are developing. Drugs reaching the fetus during this stage may have no effect, or they may cause a miscarriage, an obvious birth defect, or a permanent but subtle defect that is noticed later in life.
The risk of miscarriage almost doubles for women who drink alcohol in any form during pregnancy, especially if they drink heavily. Birth defects of the heart, brain, and face are more common among babies of smokers than among those of nonsmokers. Also, the risk of sudden infant death syndrome (SIDS) may be increased.
