Now that I think about it, I actually think it was in a discussion of pheromones, and how ethical it would be to use ones that would actually work, and someone mentioned the trial. The ethics questions about the drug were if it were possible to use like a pheromone, not about the usage for sexual dysfunction. Would such a pheromone/drug take away free will, or is using it the same as other things people do to make themselves more attractive?
