That's a great question--and applies to anyone who wants to stay healthy in a group of people making unhealthy choices. Try inviting them to do something social that you do feel comfortable with. Invite them to lunch, a gym class, or an after work drink. Or just invite them to take a 5-minute walk around the building (which will increase your daily activity too). If they're people you're close with, you can also be frank about how you feel. You can tell them that you want to socialize with them and feel a bit left out, and ask them to help you come up with a solution. Of course, if they're temporary co-workers and you don't know them well, that might be much harder. Just take the initiative to suggest activities that appeal to you, then you might have to sit out when they smoke, but you won't miss out on the chance to get to know them.
