- SMOKE THICKENS OVER CLOVE CIGARETTE INHALATION STUDY
-
- By: DENNIS McLELLAN
-
- The results of an industry-sponsored study, released this week,
- on the possible toxic effects of smoking clove cigarettes show that
- clove cigarette smoke is no more harmful to laboratory rats than
- smoke from conventional cigarettes.
-
- Scientists not connected with the study, however, caution that a
- single study on rats does not provide conclusive evidence that the
- pungent-smelling imported cigarettes from Indonesia do not cause
- lung damage in humans.
-
- The independent study, which was conducted by the Department of
- Inhalation Toxicology at the Huntingdon Research Centre in
- Huntingdon, England, is the first inhalation study made available
- to the public on clove cigarettes (or kreteks), which have come
- under attack in the past year for causing serious health problems
- and allegedly leading to the death of one Orange County teen-ager.
-
- The British inhalation study was funded by P. T. Djarum and House
- of Sampoerna, both of Indonesia, although an industry spokesman
- said the laboratory wasn't told who was backing the study. The two
- firms are the largest manufacturers of clove cigarettes -- which
- contain 60% tobacco and 40% ground cloves.
-
- Cigarettes 'Vindicated'
-
- "I think the study shows that clove cigarettes have been
- vindicated as far as being guilty of what the critics have said
- they are guilty of: that these things are much worse for you than
- non-clove cigarettes," said G. A. Avram, executive director of the
- Specialty Tobacco Council, an organization representing the major
- manufacturers and importers of clove cigarettes in the United
- States.
-
- Avram, who released the results of the 119-page study at a news
- conference in Washington, said the study "clearly establishes that
- clove cigarettes do not cause acute respiratory distress or
- anesthetize the lungs on the test animals." (Eugenol -- the major
- component of cloves-- is used as a mild dental anesthetic; critics
- of clove cigarette say the eugenol in the cigarettes numbs smokers'
- throats.)
-
- The results of the British inhalation study differ sharply from
- those of an as-yet-unpublished study conducted last year by the
- American Health Foundation, which shows that eugenol can cause
- extensive lung damage and may be lethal to laboratory animals when
- administered directly into the lung via the trachea (in contrast to
- inhalation studies, in which laboratory animals breathe smoke).
-
- Another study by the American Health Foundation, however,
- supports the findings of the British study: In that, an inhalation
- study, there were no acute toxic effects among hamsters exposed to
- clove cigarette smoke, according to Edmond LaVoie, associate
- division chief of environmental carcinogens at the nonprofit,
- independent research foundation in Valhalla, N.Y.
-
- LaVoie added, however, that "one cannot discount the data
- obtained in the intratracheal experiments because there are
- limitations in using small rodents in inhalation experiments." The
- American Health Foundation studies on clove cigarettes will be
- published soon in Archives of Toxicology, a scientific journal.
-
- In view of the findings in the British inhalation study, however,
- Avram maintains that "the burden of proof has shifted and it's now
- up to them (clove cigarette critics) to prove there is a problem
- with clove cigarettes instead of clove cigarettes being put on the
- defensive."
-
- Robert Phalen, director of the air pollution health effects
- laboratory at the College of Medicine at UC Irvine and author of
- "Inhalation Studies," a professional reference book, observed that
- the inhalation study "is important, but I'd say a single study is
- not definitive for something that has widespread use."
-
- Phalen added that "there's a segment of the population --
- somewhere around 5% -- that have very sensitive lungs. These
- people can over-respond to a variety of chemicals when inhaling.
- The rat is not a good model for those people."
-
- Moreover, Phalen said, "You can never, in a small single animal
- study, say that something is safe. Let's say clove cigarettes
- hypothetically caused one smoker in a thousand to die. You could
- never detect that in a study of human beings unless you had tens of
- thousands of people and you couldn't detect that level of risk in
- a study using less than several thousand animals."
-
- "The conduct of a single study is suggestive but in no case
- convincing evidence one way or the other unless the study is so
- designed as to be essentially foolproof and these studies are so
- complicated that they rarely can be made foolproof," said Dr. Tee
- L. Guidotti, professor of occupational medicine at the University
- of Alberta Faculty of Medicine in Edmonton, Canada, who has done
- research on clove cigarette toxicity.
-
- "We can't say anything about long-term health effects from a
- single short-term study," Guidotti said. "We do know that the
- International Agency for Research on Cancer, which is the
- international authority on such matters, has concluded that eugenol
- is a possible human carcinogen. The addition of a possibly harmful
- substance (eugenol) to an already hazardous product (cigarettes)
- can only increase the risk that much further."
-
- Lawsuits Filed
-
- In general, Guidotti added, clove cigarettes "have more tar,
- nicotine and carbon monoxide than conventional cigarettes."
-
- "I think it (Avram's assertion that clove cigarettes are as safe
- as regular cigarettes) is bunk," said Eric Lampell, attorney for
- the two Orange County families that have each filed $25-million
- lawsuits against the makers, importers and sellers of clove
- cigarettes for supplying their children with what they charge were
- "dangerous and defective" cigarettes.
-
- Anticipating possible criticism over having a vested interest in
- a study examining his own product, Avram said the Huntingdon
- Research Centre did not know until the study was completed that the
- sponsor, Avram's North Carolina law firm, was representing two
- clove cigarette manufacturers.
-
- Avram said two more inhalation studies will be forthcoming soon
- from the independent British contract research organization.
- "And," he said, "the preliminary indications we're getting are that
- they are even more encouraging from our point of view than this
- original one."
-
- Avram was scheduled to present the inhalation study Thursday to
- a state Senate committee in Maryland where legislators are
- considering a bill to ban clove cigarettes.
- Missouri and Utah currently are considering similar bills.
- Nevada and New Mexico already have banned the imports, but a
- Florida judge declared unconstitutional a 3-week-old law banning
- clove cigarettes in that state.
-
- Reacted 'Hastily'
-
- The Speciality Tobacco Council maintains that legislators have
- reacted "hastily" in banning clove cigarettes "without taking time
- to obtain a balanced appraisal on the issue."
-
- The council was formed early last year in the wake of media
- reports on the potential health hazards of smoking clove
- cigarettes, which have been sold in the United States since 1970
- but did not become popular until the early 1980s. (Sales of the
- imports, according to Avram, have dropped to about half of their
- peak of 150-170 million in 1984 as a result of the controversy.)
-
- Last March, Ron and Carole Cislaw of Costa Mesa filed a
- $25-million lawsuit, claiming that the sellers, makers, and
- importers of clove cigarettes were, among other things, negligent
- in supplying "dangerous and defective" cigarettes. Their
- 17-year-old son Tim developed shortness of breath shortly after
- smoking a clove cigarette and eventually died of respiratory
- failure. A second $25-million lawsuit was filed in July by a Buena
- Park woman whose 17-year-old allegedly contracted a debilitating
- lung ailment after smoking clove cigarettes.
-
- Last May, the U.S Centers for Disease Control reported 12 cases
- of severe illness possibly associated with smoking clove
- cigarettes. Symptoms in the 11 patients who were hospitalized,
- according to the CDC report, included pulmonary edema (blood- or
- fluid-filled lungs), bronchospasm (a constriction of the air
- passageway) and hemoptysis (coughing up blood).
-
- Minor symptoms reported to the CDC included nausea and vomiting,
- increased incidence of respiratory tract infections, worsening of
- chronic bronchitis and increased incidences and severity of asthma
- attacks. Mild coughing up of blood, the report said, has been
- reported with particular frequency. Preliminary Results
-
- The CDC report, however, stressed that a cause-and-effect
- relationship between clove cigarette smoking and the patients'
- illnesses has not been proved.
-
- When preliminary results of the the American Health Foundation
- intratracheal study were obtained by The Times last June, the
- Specialty Tobacco Council labeled the foundation's method of
- administering eugenol via the trachea into the lungs of laboratory
- animals as an "unsound scientific test."
-
- "You might regard the intratracheal instillation (method) as a
- massive overkill and it does not reflect the smoking of a (clove)
- cigarette," said Murray Senkus, a consultant for one of the major
- manufacturers of clove cigarettes in Indonesia and a former
- director of research and development for R. J. Reynolds Tobacco
- Co.
-
- LaVoie responded by saying, "We gave them (the laboratory
- animals) less than one-third the dose of eugenol which is delivered
- to the lungs by one clove cigarette: less than one-third the amount
- of eugenol in one clove cigarette kills 50% of the animals."
-
- UC Irvine's Phalen said "intratracheal studies can be useful and
- important in looking at the toxicity of something the lung has been
- exposed to. However, it is not a definitive method of
- administration for something that's inhaled. One of the principles
- of toxicology is to expose animal subjects by the same route that
- one expects human populations to be exposed."
-
- In light of the results of the American Health Foundation's own
- inhalation study on clove cigarettes, LaVoie said he is not
- surprised by the results of the British inhalation study.
-
- He maintained, however, that "because the rats used in the
- (inhalation) studies are obligatory nose breathers -- they by
- nature breathe through their nose -- only a very small portion of
- the smoke components ever reach or become deposited in the lung.
- This is an inherent deficiency of the animal model and I would say
- both models (intratracheal instillation and inhalation) do not
- mimic the way humans actively smoke."
-
- More Studies Recommended
-
- LaVoie said he could not say much about the British study because
- he hasn't seen it. "I can say that no two-month inhalation study
- using small rodents would convince me that these cigarette products
- are safe."
-
- LaVoie recommends conducting more inhalation studies that are
- "longer term and possibly more sophisticated in order to bypass
- some of the inherent differences in the inhalation of particulates
- observed with small rodents vs. man."
-
- "I think what they (Huntingdon Research Centre researchers) have
- done is an appropriate beginning and I anxiously await both details
- on the study and further studies to evaluate just how dangerous
- clove cigarettes are," said LaVoie. "Like cigarettes, they do
- adversely affect health, we just don't know how severe the degree."
-
- As Guidotti said, "We'll be going back and forth for years on the
- inhalation toxicology."
