Abstract
A vapor provision apparatus including a vapor generation chamber containing a vaporizer for generating vapor from a vapor precursor material; and an air channel wall defining an air channel between the vapor generation chamber and a vapor outlet at a mouthpiece end of the vapor provision apparatus through which a user can inhale vapor during use; wherein an inner surface of the air channel wall is provided with at least one protrusion extending into the air channel to modify (redirect) a flow of air in the air channel during use. For example, the at least one protrusion may be arranged to define one or more portions of a helical wall extending into the air channel so as to impart a degree of rotation about an axis of extent of the air channel to air flowing in the air channel during use.
