It is known as the Mosaic virus where I have read up on it, and can be a problem for all nightshade family plants, including tobacco, tomatoes, potatoes, and the eponymous nightshade.
So just like you don't mulch plants of the same family with eachothers' plant wastes so that diseases and dormant molds/fungi (even pest insect eggs) particular to the family aren't transferred to the soil and, after, to successive crops, you will want to avoid using composted tobacco on nightshades. I have been told that you don't even want people smoking around your nightshade crops for fear of infection.
This, in addition to using crops with different needs and nutrient profiles so as to not deplete the soil every year of the same nutrients, is one of the main reasons for traditional crop rotation.
