manure is too expensive for big tobacco's profit margin.  growing your own tobacco is the only way no pesticide no chemicals only manure it takes a 2 months minimum to cure tobacco,  there's more to it than just drying the leaves hanging in a tobacco barn upside down with a fire going to control the temp and enough smoke to keep away pests steam for just the right moisture content if it dries to fast it's harsh and flavorless not too much moisture or you risk mold it has to be controlled just right to keep the process inside the plant working to develop the flavor. some call it maple some call it molasses is produced in the cane and slowly drains into the leaves hanging upside down.  when it's finished that smell is incredible
