  Abstract: BACKGROUND: The Barclay cigarette   (Brown & Williamson) was introduced in 1980 in the USA in the   most expensive launch in history. In the USA and around the   world, Barclay was later determined to have a grooved filter   design that was compromised by human smokers in the normal act of   smoking, but that was measured as ultra-low tar using the   standard tar testing protocol. OBJECTIVES: To evaluate whether   Brown & Williamson knew of the compensatability of Barclay   during the design process and before it was released; to evaluate   initial responses of competing tobacco companies to Barclay,   before complaints were made to the Federal Trade Commission in   1981. METHODS: Internet databases of industry documents (Tobacco   Documents Online, Legacy Tobacco Documents Library, Brown &   Williamson Litigation discovery website, Guildford and major   company websites) were searched using key words, key dates, and   targeted searches. Documents related specifically to the   development, evaluation and release of the Barclay cigarette and   related to the responses by competing tobacco companies were   examined. RESULTS: Documents indicate the manufacturer was aware   of Barclay design problems and was planning, before release, to   respond to criticism. Competing companies quickly detected the   filter groove stratagem and considered developing their own   similar filter, but eventually backed off. CONCLUSION: The design   problems with Barclay were readily understood by cigarette   manufacturers, including the maker of Barclay, before official   governmental evaluations occurred. Testing involving measured   exposures to human smokers may in the end be crucial to   identifying problems with novel cigarette designs.
