I have always wondered about

the smoke in bars. Many of the people who go to bars also smoke. I would imagine that the smoke would clog the

receptors responsible for the unconscious perception of pheromones. I would imagine that pheromones have greater

reactions with people who don't smoke.

However, alcohol would seem to help the test environment. Pheromones

cause a small unconscious visceral reaction. Most people are programmed to ignore these emotional physical

reactions. When someone is even slightly intoxicated I would imagine they are more likely to act on instinct and

their subconscious programming.
