15. A vapor producing device comprising a capsule wherein the capsule is filled with a herbal product and comprising a shell, an upstream part and a downstream part, wherein an inlet orifice is in one or both of the upstream part and the shell, and an outlet orifice is in the downstream part, the inlet orifice and the outlet orifice comprising a multitude of perforations,
and wherein a flow-through-area A2, being a combined surface area of the perforations of the outlet orifice, is larger than a flow-through-area A1, being a combined surface area of the perforations of the inlet orifice, wherein a ratio between the flow-through-area A2 and the flow-through-area A1 is from 1.5:1 to 12:1 for reducing battery usage required to reach a temperature at which vaporization takes place wherein the vapor producing device further comprises an internal volume defining a space between the inlet orifice and the outlet orifice configured for air to move between each perforation associated with the inlet orifice and each perforation associated with the outlet orifice, and wherein a pressure reduction occurs during the inhalation process as a function of a ratio of the flow-through-area A2 of the outlet orifice over the flow-through-area A1 of the inlet orifice.
