Ok, your silence tells me you weren't kidding ...
Yes, ethyl alcohol (or ethanol, if you wish) is for food use.
I dip the glass mouthpieces or all the vapcap (except the cap) for a few hours. When the alcohol turns champagne-coloured it means that it is ready for extraction.
I do an extraction every two weeks or so.
I pour the alcohol into a large and low pot ( Do not use one with a non-stick base because then you will have to "scratch" ...) and turn on the heat to a minimum, being careful never to boil the alcohol because the cannabinoids burn.
It is a procedure to be performed with the utmost caution!
Alcohol + fire: potential danger.
Be careful!
When the alcohol has completely evaporated (I follow everything step by step) you can collect everything with a razor blade and form a ball or, as I do, lick the bowl with a few grams of CBD trim.
In this way I get a cannabis mince mixed with a hash oil.
Heavenly.
