Abstract

The invention relates to an electronic smoking device (10) with a first gas conduit (42) and a second gas conduit (46), wherein an atomizer (26) is arranged in the first gas conduit (42) and the second gas conduit bypasses the first gas conduit (42). In order to be able to change particle sizes of vapor provided by the atomizer (26), the electronic smoking device (10) is adapted to change flow resistances of the first and the second gas conduits (42, 44), while maintaining a total flow resistance of the first and the second gas conduits (42, 44).
