I tested some of the older ABV (already been vaporized) cannabis I’ve kept over the past few years using Keystone Labs Key-Box. An unknown amount of cannabis was placed in a crock pot with an unknown about of coconut oil for 36 hours. The mixture was strained, and allowed to cool before it was used for the testing kit. The test results showed the ABV was dominant in CBN (2.4mg/g), about 3 times more than the 2nd highest cannabinoid, THC (0.8mg/g). CBD and CBG were also present, at an 8th and 12th of the amount (respective) of the dominant cannabinoid, CBN.
I almost exclusively use an analog Volcano that I purchased 2007. Price was about $700, if I recall correctly, and its probably some of the better money I’ve spent, it’s been reliable, and capable. I keep it between 6 and 7, of 9 and it leaves a lighter afterburn, compared to the Mighty and Plenty. Upon use, I empty the Volcano chamber into an open container, and when that is full, I transfer it to a large freezer bag.
Previously, I’ve filled a crock pot with ABV cannabis and added butter until the cannabis was saturated. Once the butter was strained, we found a recipe that used the most butter, which happened to be gingerbread cookies.
The cookies did not provide an enjoyable effect. I shared them with people I knew, nobody that tried one took a second. I took them a few times. I found them sleepy, at best. At worst, they were nightmarishly hallucinogenic; auditorily, like there’s an intruder in your kitchen, and somatosensory, like people are trying to take your shoes off.
I ended up throwing the cookies out. I still keep the ABV, so decided to attempt to recreate the original recipe and have it tested.
The procedure was basically the same, except I substituted coconut oil for butter. I grabbed an ounce sized handful of ABV and placed it in the same crock pot, with enough coconut oil to saturate the cannabis. I left it on the ‘keep warm’ setting for 36 hours and strained the mixture through cheese cloth. After the mixture had cooled and solidified, I reheated a small portion to perform the Key-Box prep steps. Because I had already suspended the cannabinoids in a carrier oil, the test prep procedure was as simple as adding the correct portion to the provided test tube.
A couple weeks later I received an email with the results.
Here’s a few observations I had on these results.
Low Cannabinoid Concentration
Compared to what’s available from Canadian producers, this oil has a low cannabinoid content. Coconut oil has a density of 0.903g/ml. In one millilitre of the ABV oil, there’s only 4.91mg of cannabinoids, with 1.63mg being THC. Looking at about 18mL of this oil to achieve an approximate dose of 30mg THC, which is comparable to the concentration per mL of retail THC dominant oil. Alongside the THC you’d, be getting 88mg CBN, 10mg CBD and 3mg CBG.
Via the math above, in order to achieve a psychoactive dose from this oil, you end up taking triple the CBN alongside. Taking high doses of THC, 200mg+, you’re looking at 600mg of CBN along with it.
No acidic cannabinoids were detected during the test. The THC that is present does not need to be heated first to achieve psychoactive potential.
Lack of Terpenes
A hundredth of a percent of terpinol was detected in the sample, that’s it. Terpenes usually have a lower vaporization point compared to cannabinoids, so I’m not surprised to see their absence in the ABV. Alternatively, there are several terpenes with boiling points above the vaporization point of THC or CBD, so there’s a side to me that’s wondering why none show up in trace amounts.
The oil is a solid at room temperature, and is dark brown in colour. Coconut oil is opaque white, in comparison, the concoction looks sinister, despite having a light cannabinoid composition. relative to LP oil. I’m not sure if the coconut oil absorbed something else, like chlorophyll, or if the opacity of the coconut oil enables the drastic colour shift.
Let’s assume the average of all the cannabis I ran though the volcano over the years averaged 17.5% THC + 0.5%CBD, thats 180mg of cannabinoids for every gram. We’ll also assume the difference between the first assumption, and the total tested cannabinoids were removed by the Volcano. Lastly, we’ll omit values for CBG, assume all CBN present came from degraded THC, and that their molecular masses are equal.
The test results found 3.5mg/g THC and CBD, suggesting that 98% of the cannabinoids were removed from the sample (on average). I’m not certain of the exact efficiency rate for the Volcano, I’ve seen experiments that suggests it’s as low as 50%, but I often run the same material two or three times, which may explain the substantial removal. Other variables like heat setting and size of the volcano bag are also likely present here.
It was a mistake not to weigh the initial sample of cannabis used with the coconut oil. Had I kept that number, I would be able to estimate the content of the rest of the ABV. If you’re planning on repeating this, take the initial weight; would have taken a second and brought better insight.
Had I really wanted to use this test as a measure of the content of the rest of my ABV, I would have mixed all bags together, to ensure an even sample. And I would have used a larger amount, for the same reason. Then I could calculate the content of the unused portion, from the amount of cannabis and the values it tested.
Maybe my life has become too spritely, and I want to feel extremely fatigued, while hearing sounds that may, or may not be real, I figure about two tablespoons of this will bring me right back to the heart of nightmare-town.
Alternatively, I could take it in small doses for the CBN, gauging an effective dosage by the level of symptom relief.
Oral administration of the coconut oil will be more effective. If I were to bake this in the oven the THC and CBN may be further degraded or evaporated.
If you check Weedmaps in the US you can find a fairly robust offering of topical CBN products, the most sophisticated example I can give is a 10mg transdermal patch. I have no experience with this type of product. Couple of things to consider on this type of product. Not sure if their CBN is molecularly distilled, if so, you’re likely getting a superior product compared to what’s produced by ABV. Also, I’m not sure if CBN can permeate the skin or if something else is added to achieve absorption.
As a child raised by television, when I’m looking for credible information on transdermal products, I’m going to the guru; Shaquille O’Neil. Once Icy-Hot makes a CBN back patch, then Shaq will tell us the information we need to know, during the commercial break of The Price is Right. Until then, we must wait.
This oil is solid at room temperature. You’d have to shape them, probably keep them in the fridge. If your ABV test results are similar to mine, you’ll have a CBN dominant vector. That’s probably as far as I’ll wade into these waters. For all these other topics I’ve had a speculative, ‘hey, you could try it’-type attitude. For this one, I would try the oil both as an edible and a topical first before considering making it into a suppository.
With regards to cannabis not suspended in oil, ABV has trace amounts of multiple cannabinoids that could, theoretically, be purified using a distillation apparatus. For this to be a credible option, you’d need to consider the degradation of THC to CBN, which has already begun to occur in the case of my sample. If we separate the THC, which is degrading to CBN, how long will the output last as THC distillate? Furthermore, the sample needs to be heated for distillation, will it also catalyze degradation? I cannot find a distillate product that markets itself as being derived from ABV cannabis, I wouldn’t necessarily expect to see one, it’s likely not a viable retail product. But, a service that would take the by-products of home vaporization and convert them to usable concentrate; that would be a bit different.
I’d relate the take-home-message here is about the medicinal or therapeutic potential of this product. In the case of my ABV, I’d argue the amount of CBN present negates much of the recreational value of the THC, especially for higher tolerances that need to take more THC, and would end up taking more CBN as a result.
Thanks for reading this write up. I hope it sheds some light on the potential content of your own ABV or whether its worthwhile to keep it in the first place.
