If I am correct, pheromones don't produce such permanent effect. They're different compared to mental control, they induce a state, it means that you will not inducing random ideas to people. You can make people agree with you or induce effects like calm or aggression, all because they are influenced by pheromones. And yes, continuous exposure to pheromones can change something in someone's subconscious. [b]But again[/b], we not talking about two or three meetings. Now, direct mental control by voice or mental induction are about implanting ideas in the subconscious (pheromones). I think that you're aiming to another mind control variation.
