A power supply unit for an aerosol generation device includes a controller configured to determine whether an aerosol source and a flavor source contain menthol, control discharging to a first heater and a second heater by a menthol mode upon determination that the aerosol source contains menthol, and control the discharging to the first heater and the second heater by a regular mode upon determination that the aerosol source and the flavor source do not contain menthol. A manner of the discharging to the first heater in the menthol mode is different from a manner of the discharging to the first heater in the regular mode, and/or a manner of the discharging to the second heater in the menthol mode is different from a manner of the discharging to the second heater in the regular mode.

An apparatus is provided including a first cartridge with a first central passageway and a first reservoir with a first product. The first product heated within the first cartridge forms a first quantity of vapor. The apparatus further includes a second cartridge having a second central passageway axially aligned with the first central passageway when the second cartridge is connected to the first cartridge and a second reservoir having a second product. The second product heated within the second cartridge forms a second quantity of vapor that passes through the second central passageway. The apparatus also includes a mouthpiece connected to the first cartridge and configured to deliver a combination of the first and second quantities of vapor from the first central passageway to a user.

A portable device body includes a puff opening from an inner passage. A vapor source deliver into an airflow through the inner passage a vaporized content according to a program. The program includes a first phase and a second phase. Delivery according to the first phase sets and changes, according to a first phase dosage change trajectory, a nicotine dosage from a starting nicotine dosage to an ending nicotine dosage. Delivery according to the second phase sets and changes a nicotine-to-placebo ratio according to a second phase dosage change trajectory, from a starting nicotine-to-placebo ratio to an effective zero nicotine-to-placebo ratio. The first phase dosage change trajectory is configured as statistically likely to result in user shift of nicotine intake, from smoking to electronic nicotine delivery. The second phase change trajectory is configured as statistically likely to result in user elimination of nicotine intake

An aerosol generating device includes a heating element of which inner surface have different portions having different structures such that the portions of the heating element may heat corresponding areas of an aerosol generating article which is inserted in the aerosol generating device at different temperatures, thereby providing a good quality of aerosol to the user.

A dispersion device includes a first dispersion generating system, a second dispersion generating system and an outlet end element including a first outlet corresponding to the first dispersion generating system and a second outlet corresponding to the second dispersion generating system.

Disclosed is a device (10) for adjusting the quantity of two liquids that are aerosolised in order to be inhaled simultaneously by a user, characterised in that said device comprises: two tanks (105, 110), a first tank comprising a first liquid and a second tank comprising a second liquid having at least one different property, each liquid being configured to be aerosolised when this liquid undergoes a determined physical interaction; an end piece (115) for inhalation, by the user, of the aerosolised liquid coming from each tank, two aerosolisation means (120, 125) for aerosolising the first and second liquid respectively, each tank being associated with one aerosolisation means; a single autonomous source of electrical power (130) for supplying electrical power to each aerosolisation means, a means (135) for determining a ratio of liquids to be aerosolised for each liquid and a switching means (140) for alternately supplying each aerosolisation means with electrical power from the single autonomous power source, as a function of the determined ratio, the switching means comprising two pulse-width modulators installed in series or a single pulse-width modulator between the autonomous electrical power source and each aerosolisation means.
