Studies comparing existing branded cigarette packs with plain cardboard packs bearing the name and number of cigarettes in small standard font, found plain packs to be significantly less attractive.[16][17] Additionally, research in which young adults were instructed to use plain cigarette packs and subsequently asked about their feelings towards them confirmed findings that plain packaging increased negative perceptions and feelings about the pack and about smoking. Plain packs also increased behaviours such as hiding or covering the pack, smoking less around others, going without cigarettes and increased thinking about quitting.
