Systems and methods of an electronic drug delivery system for use in a treatment program (e.g., a smoking cessation program). The delivery system can include a mobile platform and a hand-held inhalation delivery device having a controller circuit coupled to a power source, sensors, aerosolizer drivers, and a rescue button, and a pod removably coupled to the delivery device. The delivery system generates an aerosol mixture from substances in the pod in accordance with the treatment program, and delivers the aerosol mixture for inhalation by a user. The controller circuit individually and dynamically controls the aerosolizer drivers to generate signals that drive a plurality of thermal, or non-thermal, aerosolizers of the pod to generate individually tailored aerosol mixtures from multiple substances in the aerosolizer pod. The generated aerosol mixtures can have various percentages of the substances, and have different aerosol droplet sizes during different portions of the treatment program.

The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. The cartridge can comprise a body defining a reservoir and defining an aerosol pathway in fluid communication with an aerosol outlet. The cartridge can further include one or more of an air entry, a splitter configured to split air entering the air entry into a plurality of air passages, an atomizer, and an aerosol forming chamber where air from the plurality of air passages is configured to mix with vapor formed by the heater to form an aerosol. Preferably, the aerosol forming chamber can be in fluid connection with the aerosol pathway. The present disclosure further can include a control device configured to receive, power, and control aerosol formation by the cartridge.

The present disclosure describes an aerosol delivery component comprising a tank defining a storage chamber for storing a first liquid aerosol precursor and an air bleed channel extending from an outside channel opening outside of the tank to an inside channel opening within the tank. The air bleed channel has a volume between 1% and 20%, e.g. greater than 10% of the volume of the storage chamber. The air bleed channel may comprise an s-bend channel for retaining the first liquid aerosol precursor in an inverted orientation of the component.

A vaporizer is disclosed. The vaporizer includes a liquid storage housing having a liquid storage cavity formed therein and a base arranged at one end of the liquid storage housing. The base includes an air inlet protruding stage that has an upper surface facing the liquid storage cavity. The upper surface is in a shape of a protrusion. The air inlet protruding stage is provided with a plurality of air inlet holes extending from the upper surface away from the liquid storage cavity.
