Morning sickness? I dont think thats a legitiment excuse to smoke while pregnant at all. Dont take what you hear off the internet as your first general source, ask your doctor if you havent already at least. I personally think smoking anything at all, is rediculously stupid while pregnant...its smoke, its not harmless, and for your still developing kid its worse.

it may make you feel better in the mornings but why even risk that, it could make your kid retarded for all you know.
