Looks like Stanelco took extracts from this research to use in the RNS and Business Wire :)

Before learning of the fall-out studies of Phillip Morris,
Inc, we published the results of comprehensive tests
documenting that cellulose acetate filter fibres were released
from modern day cigarettes. Specifically, filter fibres were
released from 12 different US cigarette brands; two brands
from each of six different US companies. All cigarettes tested
were purchased from local vendors.97 98 Cellulose acetate filter
fibres were implanted in mice for six months. The fibres withstood
degradation and retained the tobacco brown colour and
bright fluorescence of the tobacco tar that had been adsorbed
from cigarette smoke. We reported also the presence of cellulose
acetate cigarette filter fibres in human lung tissue. In his
critique of this study, tobacco spokesperson Professor Dr F
Adlkofer noted that: With high probability, the fibres which
were seen by the authors in the lungs of smokers with lung
cancer are in fact cellulose acetate fibres.15
Results of studies presented in this report have been
confirmed and extended in investigations of consenting adult
smokers. The participant smoked a popular US filter cigarette
in his/her usual manner, but was instructed not to inhale the
smoke. Mouth washes of water were collected before
smoking, at different intervals during smoking, and after
smoking. The results showed that washes collected from all
subjects and for all cigarettes smoked contained cellulose
acetate cigarette filter fibres (range 225 fibres). In contrast,
mouth washes obtained before smoking had no fibres.Notable
is that most of the filter fibres harvested from the mouth were
coated with tobacco tar.
This paper discloses that Philip Morris, Inc has known
and concealed for approximately 40 years that fibres and
particles fall-out of the filter of cigarettes during smoking.
Other companies have assessed also the discharge of filter
fibres. In addressing this filter defect, the tobacco
industrys response has been variable, ranging from denial
of the discharge of filter fibres to the development of innovative
technologies for correcting and preventing the
problem. Consumers have not been informed of the filter
defect. Further, there is no indication that existing
corrective technologies and invention have been uniformly
implemented. Summarily, the tobacco industry has been:
(a) derelict in concealing information of filter defects; (b)
negligent in implementing technologies available to
prevent or reduce the emission of filter elements; and (c)
wrongful in not investigating the toxicology and harm
associated with defective filters of todays cigarettes that
are being marketed worldwide.
