hmmmm thats a tough one
depends on the amount drunk/smoked
i did both before i got pg, drinking was easy to stop as it was a social thing, pot was harder and i cut down to a couple cones a week in early pg and cut it out alltogether after a couple months, it freaked me out too much thinking what it was doin to my bubs (and that was prob the worst time to be smoking cause the first 12 weeks is all thier development etc)
but i was a big time smoker and i managed to stop altogether, of course i get jealous seeing DP have them but i just think about the life growing inside of me and want to give her the best start possible...

i may be biased but id have to say feotal alcohol syndrome is alot worse, ive known people to smoke throughout thier pgs and thier kids are fine, not to say its good or anything, but as another BB member said smoking pot has similar effects to pg women smoking cigarettes eg low birth weight etc, but u have to worry about withdrawls, would she really want to put her newborn thru that sort of pain?? and i saw on the news recently that something like 1/3 of women who smoke cigarettes continue during pregnancy!! eeep
