Subliminal advertising techniques have increased in usage and are commonly accepted, particularly regarding cigarette smoking. Considering the high cost of such subliminal methods, their use can be justified only by tangible results, measured by an increase in cigarette sales. The results of our studies confirm the physiological and psychological effects of subliminal stimulation that have already been reported in the specialized literature. Our research on smoking prevention led us to study the sophisticated advertising strategies used by the tobacco industry. We have shown that revealing the subliminal stimuli-at least the visual ones-is extremely useful for teenagers. The enlightened teenager becomes able to recognize the subliminal manipulation concealed in advertising, and the risk of becoming its victim. Such educational efforts have their merits, particularly at the school level.
