To the Editor: Invasive aspergillosis remains
a significant cause of morbidity and mortality in immunocompromised patients,
including transplant recipients and those treated for hematological malignancy.
Exposure to airborne Aspergillus spores is considered
a major risk factor for acquiring infection. The guideline of the US Centers
for Disease Control and Prevention recommends that potential sources of fungal
spores should be eliminated to reduce the exposure of patients at high risk.1 However, the risk of invasive aspergillosis associated
with tobacco or marijuana smoking is unclear. We investigated whether Aspergillus spores are present in tobacco of commercially
available cigarettes and marijuana (marijuana is sold semilegally in the Netherlands),
and whether burning contaminated tobacco causes release of spores.
