Abstract
A vapor provision device includes a primary airflow path, internal to the vapor provision device, from an air inlet to an air outlet, wherein air is drawn from the air inlet in a downstream direction through the primary airflow path to the air outlet by user inhalation. The device further includes a vaporizer for providing vapor into the primary airflow path, wherein the vaporizer is located within or adjacent to the primary airflow path, and a trap located in the primary airflow path to inhibit the flow of liquid along the primary airflow path in an upstream direction from the trap by retaining liquid.
