Ok lol for one thing, smoking pot makes your blood pressure rise... So you should let her know that. Ok the long term and short term effects are (depending on how much you smoke, making it more severe): possible to develope add, or adhd, developes motor skills slower as a baby, colic, startles easily, eyes dont adjust to light right for the first couple weeks, and then pretty much anything else that smoking cigarettes can cause (like preterm baby, miscarrige, low birthweight, etc...). I know alot (i mean alot, and yes I know its sad) of people that smoked pot with while pregnant, and their kids turned out just fine, were happy smart babies, and they grew up with no problems(in fact I dont know anyone that has had problems with their children that have been linked to them smoking pot). Nobody really knows the true effects of pot on a baby, but these are some of the things that are believed. Some believe it doesnt even harm the baby... It all depends on how much, and how often you smoke.
