Im 21 weeks pregnant is it bad to be around people that smoke ciggarets?

Yes: There is definitely concern for 2nd hand smoke when women are pregnant. Obviously, definitely not as unhealthy as smoking yourself, but most physicians are going to recommend that you avoid 2nd hand smoke when pregnant. If someone near you is smoking indoors, you can ask politely if they would smoke outside. If you are outside, obviously, consider moving away from the smoke. Hope that helps
