Very unlikely. While sulphur is used for those purposes, the more reactive component is sodium/potassium nitrate, in gunpowder and other conventional explosives. Its presence is more indicative of an explosive than elemental sulphur is.
Everyone exhales sulphur. It is one of the sources of halitosis.
