What is the ruling on being forced to work inspecting licenses for manufactured tobacco sales and the importation of ethanol used in alcohol production? Is this considered aiding in the spread of forbidden things?

It is not permissible to work with things that are used only for unlawful purposes, such as manufactured tobacco, nor is it permissible to assist in such work. This includes working in inspection that licenses its distribution. Assisting in what is unlawful is itself unlawful, based on the Almighty's saying: "And do not cooperate in sin and aggression." "And the one who points to evil is like the one who does it," and the principle is that "means have the same rulings as their ends." As for compulsion to work, it is considered a reason for permission if it is a valid coercion from the authority, or out of necessity.
