if she do crazy things when shes high then yes
The same as anyone else's. If you do not wish to become pregnant always use a condom and/or a reliable form of birth control.
I assume this is in reference to the myth that marijuana causes sterility in men. This is completely false. So the chances of a marijuana smoker becoming impregnated by another smoker is just as likely as two non-smokers.
it depends if the 3 people smoke in the house, out of the house, around you, or not around you, etc. but the chances of getting cancer if you live with even 1 smoker are just as high as if you were the smoker yourself, so times that by 3 and you've got your answer!
the same chances as a non-smoker, because the probability of getting lung cancer only increases if you've more than 20 pack years
depends...quite good...depends on job...are you a smoker? 70 percent. depends how you live
while you smoke your pulse rate increases
The dangers of passive smoke are the same as that of a smoker. Generally speaking, you have the same chances, if not more, of getting cancer (mainly lung cancer, pancreatic cancer and throat cancer), heart attack, or a disease of the lungs called COPD. In pregnant women, the effects are devastating for the baby. The baby has a high chance of dying from SIDS (Sudden Infant Death Syndrome).
The answer is yes. As manyyoung girls take up smoking earlier then before , so more will smoke when pregnant .
I can't give you odd in percentage points but here's an anecdotal story...I got my girlfriend pregnant, 18 months ago when she was 48.5 years old. She was a smoker, about 25 lbs overweight, didn't eat right, and had a high stress job; she "shouldn't" of been able to get pregnant. She had previously been married, had only one child, and had very much wanted another one. She and her ex had not used any birth control for 12 years, trying to conceive another child, to no avail. After about a year of her and I having frequent sex, she surprised me with the news she was 9 weeks pregnant! Sadly, the baby was lost at week 11. So, what are the chances? I don't know, but it CAN happen and unless you're prepared to be an older parent, you should take the necessary precautions.
Every pregnancy is different. If the woman was a smoker before pregnancy, she will most likely still have cravings when pregnant. Otherwise, it is doubtful she will acquire the desire to smoke.
Whether or not you know you are pregnant doesn't change the circumstances. So yes, if you smoke at all while pregnant, whether you have knowledge of the little baby inside of you or not you still harm the child.
The smoker.
