Example embodiments relate to a method of protecting a surface of an e-vaping device portion from corrosion, the method including preparing a coating mixture configured to protect the surface from corrosion, and coating the surface with a protective coating based on the coating mixture, wherein the coating is performed via one of electrodeposition, dipping, spraying, and vapor deposition, and the coating mixture includes at least one of a silane and a resin.

A cartridge of an electronic vaping device includes a reservoir configured to store a pre-vapor formulation and a heating element configured to heat the pre-vapor formulation. The heating element includes a metal tube having a first end and a second end. The metal tube defines an opening therethrough. The metal tube includes a sidewall defining at least one spiral channel extending substantially continuously along a portion of the metal tube.

An inhaler device including an atomizer configured to consume a first accumulated capacity and a second accumulated capacity to generate aerosol, and a light emitting diode (LED) configured to output a notification to an inhaler of the aerosol. The inhaler device further including circuitry configured to cause the LED to function in a first mode when the first accumulated capacity, detected or estimated, is smaller than a first threshold and the second accumulated capacity, detected or estimated, is equal to or larger than a second threshold, and cause the LED to function in a second mode different from the first mode when the first accumulated capacity is smaller than the first threshold and the second accumulated capacity is smaller than the second threshold.

In one aspect, an aerosol provision system is provided. The system includes an assembly defining an opening configured to receive a replaceable consumable and a removable member releasably engaged with the assembly. The removable member is configured to form part of an outer surface of the system, and is positioned so as not to obstruct the opening.

Devices, systems, and methods are disclosed which permit ventilation therapy concurrent with humidity and aerosol drug delivery. Exemplary mixer-heaters employ alternating actuation of humidity and drug nebulizers and may use a single constant power setting for the heating section while keeping a controlled outlet temperature over the course of treatment.

Disclosed herein are aspects of portable vaporizers to deliver aliquots of heated air to material in a unitary furnace. The furnace is multipurposed reducing heat loss, air leakage and delays in availability of air aliquots at the proper temperature for use. By dividing the unitary furnace with an air permeable divider and placing material in the chamber a controller selectively providing electrical power to a heating element configured to heat air in at least an upper region of the unitary furnace. Upon application of suction to the fluid passage heated air passes into the material and vaporizes organic oils in the material and said heating a volume of air inside a unitary furnace vaporized material can be withdrawn from the fluid passage.

A portable loose-leaf material vaporizer 1 comprises a heating chamber 20 for housing loose leaf material and vaporizing one or more active agents from the loose-leaf material, a mouthpiece 3 for withdrawal of the one or more active agents vaporized from the loose-leaf material, and a processing unit. The processing unit is configured to control temperature of the heating chamber 20 and to estimate a dosage of the one or more active agents withdrawn from the vaporizer 1 based on a mathematical model. The mathematical model relates vapor generating time and loose-leaf material properties, and optionally temperature of the heating chamber 20, to the dosage of the one or more active agents withdrawn or to be withdrawn from the vaporizer 1.

Provided is pharmaceutical composition for intranasal delivery, wherein the pharmaceutical composition includes a therapeutically active ingredient including a CGRP inhibitor. Also provided is a method for delivering a CGRP inhibitor to a subject, wherein the method includes intranasally administering to the subject a composition including a therapeutically active component including a CGRP inhibitor.

An electronic smoking device is provided including a power supply portion comprising a power supply, an atomizer/liquid reservoir portion comprising a liquid reservoir storing a liquid, and an atomizer adapted to atomize the liquid stored in the liquid reservoir when operated by the power supply. The atomizer extends away from the liquid reservoir in a first direction (L). The atomizer comprises first atomizer sections, wherein each of the first atomizer sections defines an opening that is at least partly encircled by the first atomizer section. The sizes of the openings defined by the first atomizer sections decrease with increasing distance of the first atomizer sections from the liquid reservoir in the first direction.
