How to measure dosage when vaping?

[theghost]

If you make your own e juice then you should know how much DMT and PG/VG there is in it
If you use Minty Love's calcualtor you can find out the density and the weight of the ejuice

Weight the cart
Then just take a puff and weight the cart - the amount you used will be the difference in readings pre and post puff.

e.g if a draw is 10mg then you should be able to work out 10mg is a mixture of x DMT and y juice.

Whoa, there's a lot in this thread.

Sorry if it's already been mentioned, but this is what i would do.
Find "your dose" weighed in freebase. Then, inhale from your vape cart for whatever duration gets you to that level. Will take some trial and error.
