They could easily claim that a product which would otherwise would not have these risks was made into a risky product by the use of certain carcinogens present in the pesticides. The choice of pesticide is made by the tobacco company, so it is their actions that introduce the carcinogen into the product.

Seems pretty standard to me, and I would have to guess that this is the kind of lawsuit that you would probably support if the product in question was, say, red meat instead of tobacco.
