Need Advice- Awkward Smoking Situation

[WLFEO]

Here's the deal....our neighbors just moved in a couple of months ago. Nice people, lots of issues. They have a daughter, "Marsha," who has become BFFs with my daughter, "Cindy." The girls are both in elementary school.

Marsha is truly the first friend that Cindy has ever had besides being friends with the kids of my friends- and the only friend that she doesn't fight with after 15 minutes of playing together (Why do kids think play= run around the house screaming and chasing???? but that's a separate topic!). Their friendship is really good for both of them.

Cindy is not allowed to go to Marsha's house for a number of reasons (our rule), but Marsha has always been welcomed at ours. We take her to church with us, out to eat, and the girls just play a lot at our house. On the weekend she's with us pretty much 24/7 which is fine.

I am friendly with Marsha's mother but she is kind of strange to talk to...I always wonder if she's SUPER nervous, on tons of caffeine (overly- stimulated), or on drugs or what.

So anyway, here's the awkward situation..... Marsha smells like smoke so badly when she comes over now. When she first moved in, it was in the summer and she played outside a lot and her parents smoked outside a lot. Now that it's colder, everyone has moved indoors and the poor child REEKS of smoke. She says she doesn't have a lot of friends at school and I'm pretty sure it's because nobody can breathe around her. When we go pick her up, I stand on the porch, and the second the door opens I start gagging b/c of the horrible smoke smell coming from the house.

Yesterday Marsha came over and I was gagging so badly I had to send her home after about 15 minutes (luckily it was around dinner so I used that as an excuse).

So what should I do? Marsha and Cindy really benefit from being friends. I think people who smoke that much do not realize their stench. It is not Marsha's fault. I hate to think of all of the 2nd hand smoke Marsha and her brothers are breathing. It is disgusting. I can't have her over when she smells so bad. Has anybody else run into a similar situation and how did you solve it? Should I talk to the mom? It's not like she'll say, "Oh, WLFEO thinks I should stop smoking indoors so I will! That WLFEO is so clever. Why didn't I ever think of that?"

Thanks for any advice you have!
