Saturation point for BHO/QWISO oil in ethanol?

[StinkyGreen]

Has anyone here done any experiments to determine how much BHO or QWISO oil will dissolve in pure (94%) ethanol? I've seen numbers ranging from 10-50mg/mL quoted on the web, but don't know what to believe. I'm curious to know how strong you can make a tincture.

BHO and QWISO are totally missable in alcohol. Is pure cannabis oil with one drop of alcohol in it an alcohol tincture of cannabis or a cannabis tincture of alcohol?

Ah! Thank you. That explains a lot.

Seems like this would allow for pretty easy/accurate oral ingestion. I'm surprised it's not more popular. Is there a catch somewhere?

I'm making my first batch of "QWISO" (used denatured alcohol) now. I'm looking forward to experimenting with it.

It works good.

Some may not find it all that tasty by itself. If you get too high on the alcohol percentage, it burns the mouth and works best in a drink or food.

Grey Wolf, I have a couple more questions related to oil and alcohol that I'm hoping you can help me out with:

(1) After I made my oil, I tried dissolving it in 50% vodka, but it didn't work. The vodka turned amber, but most of the oil remained stuck to the bottom of the container and no amount of heating/stirring would get it to "dissolve". If THC is completely miscible in alcohol, why does this not happen in the presence of water?

(2) To salvage the above mixture, I evaporated it, redissolved it in pure ethanol, filtered it, and re-evaporated it to concentrate it. While I was evaporating it in the final step, I noticed a dark precipitate starting to form after I had boiled it down to about 1/10th its original volume. (I bottled it at this point, and just 3 drops was a good dose.) I'm wondering what this precipitate is though. As you boil away the alcohol, at some point does the oil start to separate out of the mixture? How do you achieve/determine the optimum/maximum level of concentration?

(3) I tried another experiment with some old green dragon I had made using 151 proof rum. I added water to it (which caused the mixture to turn cloudy) and boiled off the alcohol. I had hoped that this would cause the THC to fall out of solution (since it isn't soluble in water) but it didn't happen. All I have is a green cloudy non-alcoholic mixture. Why this didn't the THC precipitate out? Is there a way to get it to do so? I'm thinking my next step here will be to boil the mixture with some butter and use that to extract the THC ...

(4) Are there any rules of thumb for dosage of ingested oil? I've read 10mg/dose, but figured it was worth explicitly asking. Thanks.

Denatured alcohol extracts non active components that ethanol will not by itself, water or not. One of the techniques used to get rid of them, is to redissolve the extraction in a more selective solvent like ethanol and drop the temperature to allow it to settle out or coagulate for filtration. Re-dissolving in a non polar solvent like hexane works even better, but is harder to purge afterwards.

Oil does not separate from an alcohol mixture. It is 100% miscible in alcohol. The stuff falling out is most likely plant waxes, though they may encapsulate and carry some cannabinoids with them.

Sorry I don't have a milligram scale (10X-3) and hear conflicting dosage numbers too. Perhaps another forum member with a milligram scale has a better handle on that question?

I titrate for dosage, and with my 62% Holy Shit mix, on average one drop is about a standard pain relieving dose for a low tolerance person and about three drops for a high tolerance person. That varies depending on the strain and the patient.

There are a few ultra low tolerance patients that one drop will OD to the point of discobobulation, while double or triple dosing very high tolerance patients has minimal effect other than mounting short term memory loss and at some point, if it is a high CBN mixture, possibly slack jawed drooling.
