Pregnant and looking for a job....?

I am 6 weeks pregnant. I got laid off last week from my job that I had for almost 4 years due to budget cuts. So, this week I applied at a few places. I had an interview this morning. The job, hours, pay and benefits are wonderful....BUT....they all smoke...HEAVILY...INSIDE. I smoked for 12 years and just quit right before I tried to get pregnant. I just don't think that it would be safe for me to be around all that. I mean, the smoke hits you like a ton of bricks when you walk in the office there. Its THAT bad. But my husband and parents seem to think the benefits outweigh the risks. I don't like being pressured to take this job just cuz the benefits are good, but I also don't have a lot of options. I mean, would YOU take a job, no matter HOW good the benefits and pay, if you were gonna be subjected to bar-like smoke ALL day while pregnant?? My Mom is treating my like I'm just trying to find an excuse not to work, which is not true. Should I just take it anyway?
