Reducing THC Content in Cannabis Extracts
After months of trying, I have come to the conclusion that my cancer patient has 0, no, nada tolerance for high THC Cannabis Oils. I've tried extracts with White Rhino, Northern Lights crosses, and Blueberry. All are too high in THC and he cannot take them for more than a few weeks, even in very small doses. Although they do alleviate his pain to a point, he is so uncomfortable he stops taking it.
Which brings me to ask this question: If I had access to high CBD Strains such as CBD Crew Nordle and Critical Mass, could I heat the oil and burn off some of the THC? I know THC has lower flash points than CBD so I thought I would ask the question.
I am going to first make the oil using the standard extraction methods but if it's still too strong, I would like to know if i could cook off some of the THC.LBBill Reviewed by LBBill on .

Reducing THC Content in Cannabis Extracts
Wish I knew.
Lets think on it
A fractional distillation sounds difficult.
Will need tight temperature control in a closed system.
Don't want to just "burn off" THC, it has medical uses.
Might be able to do a column separation, but it will be messy and imprecise.
Analytical chromatography might be doable but requires some skills.
A preparative gas chromatography is ideal, but way beyond my means.
I'm wondering if it would work to separate the components in their acidic form and then decarb with heat.
Also wondering if THC and CBD can be persuaded to become salts.
That might simplify the fractionating.
If we all go ponder this, and do some reading.
We can probably figure this out.
Meet you all back here in a day or three.
Lets see what we can see.

Reducing THC Content in Cannabis Extracts
Thinking about this in it's simplest form, decarboxylation turns the THCA into THC through precise heating. If heated too long or at higher temperatures, the THC starts to degrade into CBN. Thinking maybe I can decarb at a higher temp to degrade some of the THC. I have no way of testing or confirming the results other than trial and error.
Just like you, I am a guy who reads so much on the Internet, it gives me a headache. I usually take in all the information and form my own conclusions. It's worked so far.

Howzit LB?
Had a few thoughts;
If your patient's reaction is actually to THC and THC only, this should be do-able.
(Li'l background for anyone wondering what we are on about.
CBN is an oxidation, degradation product found in weed that's way past it's prime.)
If that's really what you are after, it seems a good start would be to allow the plant to get well into senescence before harvest.
And then expose the old, browned, buds to heat and light for several months to a year.
I've recently had the "opportunity" to sample some forgotten stash.
It was mostly CBN
It had no elevation to it at all, just makes me feel tired and dull.
There are >60 actives, in varying proportion, in the raw resin.
He may be reacting to some, many, or all.
That won't be an easy call.
If it is, indeed THC alone, we need to see how he reacts to say, THCa?
It's not psychoactive until you knock off the carboxyl group.
Grow high THCa strains, harvest too early, and store at low temperatures.
Extract the oil an near freezing and store under refrigeration.
That should give you buds that are predominately CBN, yah?
You could formulate with soy lecithin to enhance the bio-availability and keep the actual oil content low as well.
Won't get him high, and he may be able to tolerate it, but if THCa is not as medically beneficial as THC, why bother?
I may have been reading about this patients reaction on a different board.
It made me wonder how well purged his oil was to begin with?
What solvent(s) was/were used?
Was it then winterized and cold filtered?
I mean, If he is actually reacting the the waxes or traces of solvent, that, we can easily fix!
Still thinkin' and readin'.
Type atcha later,

Yikes!
Just reread my post.
This:
"That should give you buds that are predominately CBN, yah?"
Should have read:
"That should give you buds that are predominately THCa, yah?"
I claim side effects.:stoned:
Sorry 'bout that.

If you watch the original Rick Simpson video, he made his first oil out of Common Hemp.
Clearly said that it need not be high THC ganja.
Plain ol' hemp would do.
It sure would solve the too high for full dose problem.
I made some "tar" from my male plants that did ablate skin tags.
If I can find some common hemp, I'll make an extract and test the hell out of it.
Legal restrictions will make that difficult to do here, legally.
Anyone out there live in a country sane enough to grow hemp?
Be happy to walk them through the extraction and testing.
It's not rocket science.

Kentuckey is growing plain hemp and TN has a bill introduced for such as well for 2014 ( I think it is that campaign where I heard about the high CBD level in Hemp)��ya never know, might be easier to get than you think�.
