So it works for hash oil
then. I believe the boiling point for THC
is quite low, much lower than nicotine
@ 247 °C - which is what the e-cig should in theory be designed for. Nicotine is a confusing substance. In it's freebase form it burns at well below it's boiling point, so when a regular ciggie is smoked, only a very small amount of the total nicotine it contains survives long enough to make it into the smoker's lungs, which is a good thing considering how toxic nicotine is.
Propylene glycol has a boiling point of 188.2° C
The other solvent used in e-cigs is glycerin, which boils @ 290° C
This gives an idea of the sort of temp range an e-cigarette's atomiser works at.
sublimes @ 190° C, so an e-cigarette should be capable of vapourising it. The question is whether or not morphine and other opium
alkaloids are soluble enough in either PG or glycerin so that the e-cigarette can deliver enough of a hit to make it worthwhile.
