A vaporizer device may include a vaporizer body configured to couple with at least one vaporizer cartridge including a first reservoir and a second reservoir. The vaporizer device may include a first aerosol generation mechanism configured to generate a first part of an aerosol by at least vaporizing a first aerosol component present in a first vaporizable material in the first reservoir. The vaporizer device may also include a second aerosol generation mechanism configured to generate a second part of the aerosol by vaporizing a first aerosol component present in a second vaporizable material at a second temperature. The first part of the aerosol and the second part of the aerosol may be delivered, via a mouthpiece, to a user of the vaporizer device.

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 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.
