You can confirm this by thinking through the fact that each need state and each live resin strain has a different composition and viscosity and therefore different vaporization characteristics…yet the buzzer goes off based on a clock.
not really, dosing is dictated not only by time but by coil temperature, drag pressure, drag volume, coil wicking, etc.
if you have a 3 second timer vape, like the dosit, these variables add enough error that the actual medical dosages vary wildly.
An easy example : hit a vape with a timer over and over again. the last hits will almost always have a much strong mouth and denser vapor than the hits prior -- this is because the coil and vaporization 'areas' are now pre-heated from the previous hits and require less energy overall for the same dosage, but this rate varies so wildly that it's an extremely difficult task for a vaporizer to be as dynamic as the dosing rate errors.
this was supposed to get fixed with temperature controlled coils, but it only helps things a bit. What someone needs to do is make a vape profile that'll create a dynamic drag time based off of those error variables, but I have yet to encounter such a device.
Vape cartridges are nowhere near precise enough for normal drug delivery, even with a timer attached. It's just not a precision dosing method. Remember that pharmaceutical users wouldn't have any baseline to work with, whereas vape pen users have calibrated themselves over many doses across many sessions.
