1. An apparatus comprising:
a reservoir comprising a liquid barrier defining a compartment containing a liquid vaporizable material;
a first heater configured to vaporize the liquid vaporizable material to form a first vapor;
a draw channel configured for passage of the first vapor formed by the first heater, the draw channel defined by a part of the liquid barrier and separated from the compartment by the liquid barrier, the draw channel comprising the first heater; and
a porous substrate including an elutable material, the porous substrate positioned downstream from the first heater, the porous substrate positioned outside of the compartment and within and across the draw channel such that airflow within the draw channel and the first vapor is passed through the porous substrate in order to exit the draw channel,
a second heater positioned on an interior surface of the draw channel and in contact with the porous substrate, the second heater configured to heat the elutable material to a temperature that is below a vaporization temperature for the elutable material, and
wherein an inhalable aerosol is formable by passing the first vapor through the porous substrate and combining the first vapor with the elutable material of the porous substrate, wherein the second heater is positioned downstream of the first heater.
