Is THC to CBN a home brew possibility?

[zosos]

HI,
I have a clean extract of Hawaiian Haze, and am wondering if The THC (about 3%) can be converted to CBN. I have read quite a bit about this and have come to no real conclusions.

Been vaping as is, which is Awesome BTW.

But others want it without THC.

Yes ofcause, cannabinol (CBN) is the nonenzymatic oxidation byproduct of THC and is most commonly an artifact found after prolonged storage, Its also the only chemical in our plants responsible for aiding sleep, There are two methods to do this, prolong the storage of your bud or you can decarboxylate your bud for longer and at slightly lower temps, 60-65c (140 - 149 F) over a period of 1-2 hours, your thc will be converted into CBN, in you case you want to decarboxylate your extract, the exact 3% you trying to achieve will only be able to be done by testing the % amounts of CBN within the extract as you decarboxylate

Thank you for the reply,

The goal is to go from 3% to zero THC.... or less :)

so..... with heat (145°±), and enough time, all of the THC theoretically will convert? Is it that simple?

Does it need to be @ reduced pressure (vacuum)?
Will it work under high pressure (500 psi)?

my simple mind

Use an oven at about 230 - 240 F for about 1-2 hours, that's should be enough. The goal is to bake the extract / bud slowly. Too much heat for prolonged time will burn it and most times give it a crispy / burnt taste, you don't want that. All or most of your thc should be converted to CBN. I would also recommend converting THC to CBN by baking / carboxylating the buds before extraction

Go back to school and don't cheat this time ya cheater

I don't think anyone will understand the comment.

Lance Griffin from Extraction Magazine writes:“The most common and obvious strategy beyond natural aging is to apply heat. According to Wang et al, “Δ-9-THC itself readily oxidizes to cannabinol (CBN) with oxygen and light during the decarboxylation process.” A different study published in 2005 found that this oxidation occurred above 150° C (302° F) given a 15-minute decarboxylation period. The typical decarb process employs lower temperatures and longer times to avoid this conversion and preserve Δ-9-THC; amping up the temperature may thus prove useful for CBN seekers. However, using a vacuum oven mitigates this conversion.” Read the rest of Lance Griffin’s article here.

The other strategy for converting THC into CBN is the use of UV light as an alternative to heat. As mentioned previously, light degrades cannabis and hemp, facilitating a natural conversion of THC into CBN.
However—and here’s the catch—to extract CBN at a large scale in a lab setting, neither UV light nor heat is used to convert THC to CBN for the purposes of isolation. Typically, it is a much more complicated and well-guarded proprietary SOP involving refluxing the THC, dissolved in specific solvents, and usually in the presence of precious metal catalysts.

Hope that helps.
Very interesting the medicinal possibilities from Cbn.

The UV light sounds interesting might even try it myself

Makes me think of the Morrocan hash high in Cbn.
Traditionally the plants were dried on rooftops in the sun, that may explain the high level of Cbn.

Do you ever have anything good to say? Or u just a hater ?

The comment didn't make much sense to me either

Same way alot of the stuff is dried here and sold, cheap sleepy stuff not worth the smoke

so... not so simple I guess, I would like to keep the extract intact.
I will try heating as prescribed, and look for testing methods to reveal the results.
I'll let y'all know...

Thanks! :)

I have some low grade bud that has been stored for 2-3 years, was thinking about making it into bubble hash, would it be high in CBN?
It would be great if it did

Only one way to find out

 

[zosos]

Well.... Finally got around to testing heated vs original.... performed thin layer chromatography on samples.... THC levels went up... So...???
:)

 

[lvstealth]

that would seem impossible, lol. so, how much did they go up? can you repeat the test? the whole thing - heating and testing?
