klue - which friendship block are you making? there are several of them out there -
blocks that come from a smoky environment?
maybe they could either be washed or aired outside before sending them in? washing does require repressing, but it can be done -
there is also a difference between where people only smoke outside and where six people are smoking five packs a day each inside in a 10 x 10 room -
maybe have a non-smoking friend sniff them and go from there?
when my DH smokes, he does so outside, but I can tell from 20 feet away when he comes in that he just had a smoke. the UGH factor sort of fades as my nose gets deaf to the smell.
It was thoughtful of this person to ask.
