Reports a simple extraction method for the simultaneous measurement of nicotine and menthol. Says this method is used to study the effects of air dilution on puff-by-puff deliveries of nicotine and menthol. Finds increased air dilution enriches the nicotine content of tar more than menthol and this procedure is useful for analyzing cigarette filler.

Nicotine applied as free nicotine and nicotine tartrate to different tobaccos to increase N/T ratios in smoke. Nicotine was delivered in smoke in the same manner as naturally ocurring nicotine. The nicotine treated samples were so strong that they were unpleasant to smoke. "Only a small addition of free nicotine was needed to provide the impact of a higher nicotine cigarette." Suggestions for further work: Determine level of free nicotine necessary to provide "popular" impact; investigate ways of aplying nicotine/ nicotine salts to RL; investigate nicotine additions to different parts of production process.

Reports on a exploratory study of menthol smokers' perceptions of 'menthol' versus 'non-menthol' cigarettes. Describes study methods, involving 37 participants interviewed in five focus groups (according to gender, African American, White) and outlines how participants were selected. Comments that menthol smokers predominantly attribute irritation to tobacco not to menthol content; in fact, most participants viewed smoking generally irritating if not done in moderation. Notes that respondents pinpointed irritation as occurring in the throat than in any other part of the body. Discusses participants' perceptions of taste and flavor and irritation and harshness with reference to tobacco blend and menthol content. Requests participant feedback to various concept statements being studied, for example: "This Menthol Cigarette Has The Highest Level of Menthol Taste Possible Without High Irritation," which resulted in a predominantly negative reaction, except for the black male focus group. Gauges responses for possible names of the new brand. Reports that participants were asked to smoke four different cigarette brands (Newport, Salem, Kool, Special Menthol) at the end of the session, noting that "[t]hey were unable to relate a cigarette" to the concepts that had been discussed. States that the Special Menthol cigarette was received as being similar in harshness and strength to Kools, which was received favorably by the African-American male focus group. Includes an appendix, which contains background and demographic information of all the focus group participants, interview schedule, and outline of the group interview proceedings.

Memo details use of chocolate in tobacco products and suggestions for substitutes. States that there are two decoded memos concerning PM use of chocolate in tobacco but there are no attachments. Largest use of chocolate is in the form of cocoa shells.

Memo states that cocoa is in continuous use as a tobacco additive for the treatment of the burley part of the so-called American blend, This is true for cigarettes manufactured in the U.S., Europe and elsewhere in the world. References NCI study but states scepticism around findings. No change has occurred in the practice of including cocoa in the formulation of casing for burley tobaccos. Cocoa is used in blended cigarettes.

Abstract of Effect of chocolate in migraine: a double blind study. Concludes that chocolate on its own is rarely a precipitant of migraine. Second abstract (Food allergies and migraine) concludes when an average of 10 common foods (including chocolate and milk) were avoided there was a dramatic fall in the number of headaches per month.

Description of possible techniques for obtaining a flat puffed profile for a cigarette. Includes use of coated holes which open during smoking to provide air dilution in the latter half of the cigarette, and use of burn accelerator to increase static burn rate at back end of cigarette. Recommends further development and patenting of ideas.

Memo lists the nontobacco additives contained in the finished reconstituted sheets (DAP-BL and DAP-RCB) based on a 12% moisture content.

Report details alternative methods of casing to reduce PG loses or eliminate PG including: casing of ES after expansion, casing at superwet cylinder, elimination of PG from casing. Attributes monitored include: flavor differences, equilibrium moistures, cylinder volumes, firmness data, sieve fractions and casing recoveries. Concludes that the most feasible solution was the elimination of PG from ES casing.
