Electronic aerosol provision device

An electronic aerosol provision system, comprising an air pathway between an air inlet and an air outlet; and a vaporiser for generating vapour into the air pathway; where the air pathway between the air inlet and the vaporiser is configured to support laminar airflow. The air pathway between the air inlet and the vaporiser includes one or more curved portions, where each of the one or more curved portions has a radius of curvature greater than 5 mm. The laminar flow helps to prevent the aerosol from mixing prematurely with the incoming air, which can lead to improved vaporization efficiency and a more consistent aerosol output.
