If you smoke, your breath contains 2,5-dimethylfuran. A team of Catalan researchers have proved that the presence of this chemical compound indicates that a person has smoked in the last three days. This substance does not appear in the breath of non-smokers, unless they have been in direct contact with tobacco smoke for a long time.
