Abstract: A scent strip for use with digital entertainment media contains a volatile mixture of a detectable scent and an imperceptible pheromone which is adhesively attached to a digital entertainment medium package, e.g., a CD/DVD case or VHS cassette, or to a print medium, e.g., business card or magazine. The strip includes a peelable cover layer, that, when removed, releases the contained volatile mixture causing a desired modification in behavior, such as increasing a person's libido. The cover layer can be removed in accordance with written instructions provided with the strip indicating a cue, e.g., during payback of the medium, when the cover layer should be removed, e.g., during a particular scene in a movie.
