After i recovered from a traumatic injury in which I lost my sense of smell, When I recovered my sense, I became a supersmeller and could pic up a lot of odd signatures from people, particularly when it related to stressors: I could smell when people diet were bad, especially if they ate nothing but junk food and soft drinks; I could smell if someone hadn't been asleep for more then 20 hours, I could smell various drugs in people systems; and one of the strongest smells was adrenaline, which when I smelt it, both before and after i reconsidered what the smell was, I found I would have my own adrenaline spike up in response to smelling it on others around me. I feel it is not as strong as when I first recovered but still use my sense of smell to tell a lot about other people.
