Okay and i want to know is the electric segaret safe in pregnancy ??

No, it's not: Whether it is SAFER than cigarettes, however, is another question. It most likely is safer, because it has fewer dangerous chemicals than burnt tobacco does, but it still has a lot of unknowns. Different e-cigs and devices for delivering the nicotine come with different liquid propellants, and many of these have formaldehyde and other toxins. Best thing is to quit. 2nd best-nicotine patches etc.
