Dr Hammond suggests, however, the firm went beyond merely investigating how people smoked. A series of internal documents from the late 1970s and early 1980s shows that BAT at least thought about applying this knowledge to cigarette design. A research report from 1979 puts it thus: “There are three major design features which can be used either individually or in combination to manipulate delivery levels; filtration, paper permeability, and filter-tip ventilation.” A conference paper from 1983 says, “The challenge would be to reduce the mainstream nicotine determined by standard smoking-machine measurement while increasing the amount that would actually be absorbed by the smoker”. Another conference paper, from 1984, says: “（5）We should strive to achieve this effect without appearing to have a cigarette that cheats the league table. Ideally it should appear to be no different from a normal cigarette...It should also be capable of delivering up to 100% more than its machine delivery.”

不过哈蒙德医生表示，英美公司所调查的不仅仅人们的吸烟方式。英美公司上世纪70年代末、80年代初的一系列内部文献表明，该公司至少曾考虑过将这一知识用于卷烟设计。1979年的一份研究报告上这样说道：“可分别或联合应用与设计有关的三个要素，即过滤、烟卷包装纸的通透性以及过滤嘴的通气效果，来控制焦油和尼古丁的释放水平。”1983年一份会议论文也提到，“关键在于，要在提高吸烟者尼古丁实际吸收量的同时，减少可被标准检测方法测定到的含量。”1984年另一份会议论文说：“我们应当努力达到这一效果并能在检测中蒙混过关。理想化的结果是，这种香烟看上去应与一般香烟无任何差异…… 并且释放的尼古丁及焦油量要比机器释放的高出100%。”
