a third opening disposed through a wall of said mouthpiece, wherein said electroconductive textile heating element, said reservoir, said power element and said power connect element are disposed inside said first cavity, and wherein said first velocity of said flow contributes to mixing said flow with a vapor in a space adjacent to said electroconductive textile heating element.

2. A handheld electronic vaporizing device according to claim 1 , wherein said deformable reservoir is formed from a material selected from the group consisting of polymers and metal/polymer composites.

3. A handheld electronic vaporizing device according to claim 2 , wherein said deformable reservoir comprises polyester with aluminum printed exterior.

4. A handheld electronic vaporizing device according to claim 1 , wherein said electroconductive textile heating element includes a fabric selected from the group consisting of fabric with metalized coating, fabric with electro-conductive coating, and fabric incorporating woven metal strands.

5. A handheld electronic vaporizing device according to claim 4 , wherein said electroconductive textile heating element comprises ultra thin grade stainless steel wire cloth.

6. A handheld electronic vaporizing device according to claim 1 , wherein said electroconductive textile heating element is electrically responsive to said capacitive touch sensor element.

7. A handheld electronic vaporizing device according to claim 1 , wherein said electroconductive textile heating element is activated by a user's touch on said capacitive touch sensor element.

8. A handheld electronic vaporizing device according to claim 1 , wherein said electroconductive textile heating element is regulated to heat a volatile e-liquid to a pre-set temperature.

9. A handheld electronic vaporizing device according to claim 8 , wherein said pre-set temperature is a temperature of vaporization of said volatile e-liquid.

10. A handheld electronic vaporizing device according to claim 1 , wherein said capacitive touch sensor element regulates duty cycles of said electroconductive textile heating element.

11. A handheld electronic vaporizing device according to claim 1 , wherein said light element comprises an LED light.

12. A handheld electronic vaporizing device according to claim 1 , wherein said light element is electrically responsive to said capacitive touch sensor element.

13. A handheld electronic vaporizing device according to claim 1 , wherein said capacitive touch sensor element regulates duty cycles of said light element.

14. A method for drawing vapor from a handheld electronic vaporization device comprising a body defining a first cavity, a mouthpiece connected to said body, said mouthpiece defining a second cavity, an electroconductive textile heating element, a deformable reservoir containing volatile e-liquid, a power element, a power connect element, a capacitive touch sensor element, a light element, a first opening and a first valve located on a wall of said body to provide for a flow of air directly into said first cavity, wherein said first valve is normally closed and is opened by said flow, wherein said flow includes only air as said flow passes into said first cavity, and wherein said first opening includes a first opening area and said flow upon passing through said first opening and said first valve directly into said first cavity has a first velocity,

a second opening and a second valve connecting said first cavity and said second cavity, wherein said second valve is normally closed and is opened by said flow, wherein said flow passes from said first cavity through said second opening and said second valve and into said second cavity, wherein said flow causes said first valve and said second valve to be open at the same time, and wherein said second opening includes a second opening area greater than said first opening area and said flow after passing through said second opening has a second velocity, said first velocity being greater than said second velocity, and a third opening disposed through a wall of said mouthpiece, wherein said electroconductive textile heating element, said reservoir, said power element and said power connect element are disposed inside said first cavity, and wherein said first velocity of said flow contributes to mixing said flow with a vapor in a space adjacent to said electroconductive textile heating element, the method comprising:

supplying electrical power to said electroconductive textile heating element; heating said volatile e-liquid to a pre-set temperature;

creating an area of negative pressure external to said second cavity, said negative pressure causing said flow to pass from an exterior of said body through said first opening and said first valve, combine with vaporized e-liquid in said space adjacent to said electroconductive textile heating element, and continue to pass from said first cavity to said second opening, said second valve, said second cavity and through said third opening.

15. A method according to claim 14 , wherein said pre-set temperature is a temperature of vaporization of said volatile e-liquid.

16. A handheld electronic vaporizing device according to claim 1 further comprising: a pressure sensor element disposed within said first cavity or said second cavity; and

wherein said light element is disposed on a surface of said body,

wherein said processor is disposed inside said first cavity, and

wherein said instructions, when executed by said processor cause said processor, during an activation of said handheld electronic vaporizing device, to:

determine a delivered dose of a compound based on said pressure signal,

determine a relative dose of said compound by comparing said delivered dose to a standard dose of said compound, and

control said light element based on said relative dose such that said light element changes during said activation to indicate a level of said relative dose, said level indicated by a change in said light element of at least one of a change in intensity of said light element and a change in color of said light element.
