1. A source material cartridge configured for the delivery of an active substance to a user via inhalation, comprising:
one or more sections isolated from each other, each section comprising source material;
said source material comprising at least one active substance releasable by vaporization; said source material arranged to allow a flow of air there through;
wherein said source material in each of said one or more sections is protected by a sealant impermeable to air, said sealant comprising a control region which includes a temperature sensitive material which is configured to deform in response to a change in temperature; wherein said control region is positioned and configured so that the change in temperature opens at least one opening through said sealant to allow air to flow through the source material of one or more selected sections to deliver said at least one active substance to a user; wherein said sealant is positioned in contact with said source material and configured to heat said source material when said sealant in contact with said source material is heated.
