Method and apparatus for generating a volatilized liquid

A method of programmable generation of volatilized material, comprising:

• supplying liquid material from a liquid supply to at least one flow passage having an outlet;
• heating the flow passage with at least one heater to a temperature sufficient to volatilize the liquid material in the flow passage such that the volatilized material exits from the outlet of the flow passage;
• and
• controlling operation of a valve in fluid communication with the outlet of the flow passage such that the volatilized material or aerosol (i) flows through a first flow path in fluid communication with the outlet of the flow passage when the heater is in a non-conforming condition and (ii) flows through a second flow path, which is in fluid communication with the outlet of the flow passage and different from the first flow path, when the heater is in a confirming condition.
