Please help put my mind at ease but be honest

So tonight my husband and I went to a party to celebrate a friends birthday. There was drinking (not for me obviously) but there was also smoking....a lot but most of the time we were outside or i  the garage with the door up...but pretty much everyone there was a smoker but me...I'm almost 8 weeks. Should I be worried having been around it for an extended amount of time? This isn't something we do a lot of (parties) I just want to know the baby is ok....
