Question of the Week

We received a handful of tomato starts from a friend who occasionally smokes "at a distance" from their home/family (don't know how far, but goal is to not smell of anything around family/house). How wary/careful should we be about these starts possibly being infected, and if so, what precautionary measures should we take? We're probably going to just return the gift, but since there are still a number of smokers in our town, is there a concern about any airborne particles affecting us?
