Product Design
Smoke Constituents and Their Relation to Quality: Bristol Conference, April, 1954
Abstract
Notes the industry's moral responsibility, legal necessity, and the technological importance of understanding it's product and that industry must be able to make authoritative statements regarding tobacco. Examines properties of nicotine, describes chemical reactions in each part of cigarette, and compares sidestream and mainstream smoke. Compares differences in tobacco types, explains nicotine delivery and manipulation by use of additives.

our serious consideration, if not our aggressive investi~atlon, l~e are bound,
however, to a~opt the approach that the initial and the most i~portant appeal of a
'""~ cigarette lies in the or~.anoleptic response. Our tools for measurement, crude as
'~i they are, are the best we have been able to employ thus far. This is, nevertheless
~ered~y an interin ~eans of dealing uith the problem and we must ever be alert to the
" pOssibility that ~e may find a measurable p~siolo~ical or psycholocical response
!' that is of equal or even greater significance than taste. The cardiovascular elf acts
~ of nicotine, for example, are well recognized a~d o~ significant ~agnitude ao that
Łt has been possible in recent years to relate this response to the campnsition of
the cigarette and its smoke. There has been Sncreesing evidence of interest on the

If we learn that an~ of them are a source of ill-effects we will ~ant to learn also

specific chemicals will be of little value until we reduce our technics to a ~uan~i-
