You seem to have come to a remedy that you feel happy with despite the funny, but useless advice given by most of us. If you read through the postings on both the related topics you will find some GOOD ADVICE.
On the subject of smoke from fires being carcinogenic, it's the type of material on fire that causes the problem dependant on the concentration and length of exposure. After 30 years of exposure it's a subject of interest to me, and your neighbours doctor needs to revisit medical school if they are saying that the minute risk of exposure that might be presenting to your neighbour has caused a medical problem. Don't worry about any harm caused, it has nothing to do with you or BBQing.
