What is the ruling on working as an administrative employee in a company that produces electronic cigarettes, or in other projects affiliated with it, if the original capital for these projects comes from the profits of the electronic cigarette company?

Electronic cigarettes are forbidden due to their harm, and it is impermissible to work for a company that sells them. As for other companies, it is permissible to work for them if their activity is lawful. The fact that their capital originates from the profits of the forbidden electronic cigarette company does not affect this, for the prohibition of wealth is connected to the responsibility of its earner, not to the essence of the wealth itself.
