bidi = Diospyrus + tabac = cancer + ...?

Bidi, an age-old form of indigenous smoking is used widely by
the people of lower socioeconomic status in India, Bangladesh,
Nepal, Pakistan and other south Asian countries. It is made of
about 0.2– 0.5 g raw, dried and crushed tobacco flakes (naturally
cured) rolled by hand in tendu leaf (Diospyrus mebunoxylon or
Diospyrus ebenum) or white paper. Nicotine and tar ("goudrons") content are
higher in bidi than that of a cigarette.

Bidi smoking poses greater OR than cigarette
smoking in developing cancer of esophagus, stomach, larynx,
lung, cancer of cervix of the smokers’ female partner, thrombo-
angiitis obliterans and other chronic conditions. Cessation of
bidi smoking is therefore likely to prevent thousands of death from
a variety of cancers as well as morbidity from various chronic
conditions.

(because bidi smokers belong to lower socioeconomic
strata of the society, inadequate oral hygiene, low access to health care, etc...

might also play important role in this regard)
