Uh... what? Have you ever run a GC? The % numbers are from peaks, these peak numbers are in relation to everything in the sample that is detected, not just the 3 cannabinoids that have internal standards and are being reported. really...?

1. My message was a response to the following:

"I still disagree! it is a percent of the weight of the sample." THC percentages are not in relation to "the weight of the sample."

2. I did not say what you replied with as if I had said it. I did not say THC was a percentage of "the 3 cannabinoids that have internal standards."I said "THC percentages are in relation to all known cannabinoids." If that is not how it is done then the DEA does not know how it is done because that came from a DEA agent who worked at the main DEA offices in DC and was my cousin's best friend.

And this can be found in the World of Seeds information about their Afghan Kush.

THC Level: 21.6% measured upon the rest of cannabinoids. 7.4% measured upon the rest of organic substances belonging to buds like: amino-acids, sugars, terpenoids, vegetal hormones, and cannabinoids (determined by gas chromatography coupled with mass spectrometry)

http://en.seedfinder.eu/strain-info/Afgan_Kush/World_of_Seeds_Bank/

But then maybe the World of Seeds breeders do not know how their own strains are actually tested and just thought the THC percentage was "measured upon the rest of cannabinoids," as I previously stated.

That is still not true. The THC% is relative to all parts in the sample. The other parts do not need to be known to have peaks and be part of the total analysis.

So the DEA does not understand THC testing and percentages and the World of Seeds does not know how their own strains are tested and how THC percentages are determined.

Interesting.

This is true of all GC or HPLC analysis. I think you have misunderstood something along the way. I actually studied GC in college so I'm just putting the simple facts out there.

Ive never seen analysis reported like this so its hard to say where/how they got their numbers. If its 7.4% THC that could be normal (albeit low). I find their use of the word "upon" to be unclear.

If you read the Laboratory Validation, in particular section 2.7 (Extraction Efficiency) and 2.8 (Selectivity and 2.9) (Specificity) the extraction of cannabinoids is referred to. That is what is then tested. THC percentages are in relation to all known cannabinoids.

I asked the folks at full spectrum labs about this, they told me that the THC percentage is in fact % of the total sample. A 1 gram sample of raw bud with 15% thc would contain .15 grams of thc. This is from the lab in Denver.




Email:
Hello lab people,
I've gotta quick question for you. If a sample contains 15% thc, is that 15% by weight of the raw plant material? or is that 15% of the resins extracted with hexane? would a 1 gram sample of this raw product contain .15 grams of actual THC?
Yes a 15% THC sample would have 0.15 g of THC within a 1 g sample.
I don't understand where you are getting hexane into the equation.




Does your method of testing get different results than other methods? does the result from liquid chromatography differ much from say gas chromatography?
Yes we see different results. Depending on the equipment and the detector being utilized results will very. I have attached a paper on THC-A that will show reasoning behind some of the differences (mainly GC vs HPLC).
I do not know you level of understanding you have on this matter. Please let me know if you would like a simple explanation of the paper or even THC vs THC-A.

Thanks folks,

They sent me a pdf of technical stuff thats over my head. I'm not sure how to share a pdf with rollitup?

You have to load .pdf files to a filesharing site first. Robert, top dog at Full Spectrum Lab, is very well informed and the top lab scientist in the US imo, and then some. Thanks for posting that email.

I smoked ak47 shipped from amsterdam to here and it was nice :) but once my friend got some weed called Cro in london dunno the actual strain name but i smoked half a joint and there was no white in my eyes felt like i was going crazy and my face and hands turned white and i think i was about to vomit but i held it in

Nice, no regard for quantity, quality, aesthetic values of the plant. Never thought about what you may or may not have the skill to actually grow. You just want whats gonna F**K you up the most. Right Buddy?
What are you 14 years old? Grow up. People like you are the reason marijuana is so demonized. You wouldn't know the difference between 18% and 23%. Either way you're gonna be stoned.
Find a strain for better reasons then "whats gonna F me up the most?"

No, people like him are not the reason marijuana is demonized. It's taboo because to the majortiy of society thinks all drugs are taboo.

Get the fuck out of here with that mentality. Likewise someone could criticize you for thinking that marijuana should only be grown for medical purposes. WRONG, marijuana was put on this planet for anyone's consumption, for ANY REASON. Fuck whatever reason you think it should be for, it's whatever anyone wants to do with it. It's your right as a human being to consume marijuana as you please, for whatever reason you please.

So 25% leads us to "almost all", lol at your math. THC makes up about half of what is in trichome heads (hash) just for starters, so the "fraction" you mention is 1/2 to 9/10ths, a pretty large fraction. And 25% is high for flowers, but very real. You do realize that there is THC in the trichomes and the actual plant matter right?

80 to 90% numbers are only showing up on solvent extract. For the record, butane is an extremely good solvent for cannabinoids and achieving 80 to 90% is not hard when it comes to bho. Anyone doing a two solvent extraction (ie bho followed by an iso wash) can easily get above 80% THC, just putting that out there because its a fact.


LMAO brah, you are too much for me today. SOOOOO... as a hash maker I'll tell you that 20% yields on ice water and dry screen are possible, I got over 20% last week with my chernobyl using frigging ice water and trim. Solvent extractions commonly yield over 20%, very commonly, you should ask around. 10 to 15% is common for physical extracts, but as my research with Steep Hill Lab shows, the plant material still has lots of THC after extraction that could've been extracted with solvents. Physical extraction only gets 1/2 the THC on the trim. So a 10 to 15% yield of 50% THC means that there is another 10 to 15% THC still on that trim I compost. Go to page 46. When I extract flowers instead of trim the yields are way over 20%

The inaccuracy of crappy low-overhead labs do not make Steep Hill Lab's numbers less accurate. Again, you can't let the crappy inaccurate (low overhead) labs convince you that the professional labs are not accurate. The ring test shows how inaccurate the smaller labs are, but that doesn't make the established labs inaccurate. We need standardization in the cannabinoid testing industry, but that won't happen until its taken over by the govt.

Untested but 20%+ hash yields. Chernobyl

You seem to be misunderstanding what I am saying. All that I am saying is that they are not giving you a % of weight of the sample but rather a % in relation to other compounds being searched for. If you studied GS/MS in school then you would know this.

That is the exact question I asked Full Spectrum Labs. Do you believe they are wrong?

My cousen's sister's brother's mother friends fathers sons cousens friend of friends grew stuff that was 100% thc. lmao... if you guy's are going to post high thc can you please post a link to the seed bank so some of use dumb poor asses can maybe grow better pot. I was looking at attitudes site and the most I seen was 24% on some of them. hell most of the dirt weed I have smoked I am lucky it had 8% and i still got high after 10 joints..I want to grow something that will have me seeing god after 2 hits. I am all ready coucklocked now and I did not even smoke yet. sorry about my rant as I pack a bowl so I shut up for the rest of the day

Full spectrum also gives a breakdown of all the other cannabinoids, and they don't add up to 100%

What's your point? You do know that there are over 60 known cannabinoids, not just the 5 they list right? In order to analyze a sample you have to know the specific mass of a particular compound and test for it. They are not breaking down what makes up the entire plant, read up on how GC/MS works and maybe you'll understand.

You should send the lab an email, asking them more detailed questions than I did. Until I hear from a reputable lab something different, I'm gonna have to continue to believe that they meant what they said.

its going to take a scientist to lead that horse to water. yeah the lab is wrong and stoned is right. lol...
hope he emails or calls them because we've been at this for a long time.
