Smoke

Caption

This image shows smoke. Weizmann Institute of Science researchers exposed smokers to pairs of smells -- cigarettes together with that of rotten eggs or fish -- as the subjects slept, and then asked them to record how many cigarettes they smoked in the following week. The study revealed a significant reduction in smoking following conditioning during sleep.
