THC % Question?

[MADISM]

How can i measure the % THC? I want to know how potent the weed is.
Is there any test out there or a way that you can do this?
Thanks

Couldn't have said it any better myself , best way to judge is by sampling. After all its up to the individual's body chemistry

I 've seen cheap test kits that are supposed to measure THC% but I m sure they are not working well / don't give any accurate results.

There are more expensive ways if you're interested in testing THC % , like using Gas Chromatography but you need a lab and its not easy to get accurate measurements without experienced lab technicians.

Having said all that THC% does not indicate potency as there are strains with higher THC % and they can be perceived as less potent than samples with higher THC%. There are other substances that affect the high in the drug containing resin. A strain with high THC is usually better/stronger but not always.

wow big difference

Could you send a link to those test kits? I'm really interested in this, I use a 500x usb microscope for the tricomes. When tricomes change from clear to cloudy to amber does the potence of thc increase? or does the thc level remain constant with the strain and the caniboids change as the tricomes change colors?
Thanks for the help. There just doesn't seem to be alot of info on potency.

Never seen nine bar before but shwag has about that much thc. Is it hash made from ditchweed or what?

i've heard those test kits don't work too good but i've never personally used one..the site seems to be down. when u have trichs turning from cloudy amber, the thc degrades to cbd i believe...that being said, it's a good idea to let the trichs amber up a bit before harvesting if you're looking for potency\couchlock..

Canna had a Gas Cromatography lab @Spannabis a few weeks ago, I and 2 mates got nice printouts that also included CBD & CBM iirc, Sagarmatha were very happy with the result of one of theirs and asked for a copy of the printout.

wow thats a sad comparison i have never seen such low grade hash in cali. anyways use cold water extraction or better yet alcohol or butane extracts to produce good hash even low quality smoke will produce good potency using the methods i have mentioned. peace

 

[bicycle racer]

really 3.7 thc where oh where would anyone buy that. what horrible method could be used to create such crap. even a very crappy strain is much higher in thc crazy. never heard of that.

Greetings Madism.

I think you might be looking for something like this:


I forget where i got the link, but whoever posted it was happy with the results.

I've been thinking about getting one myself.

 

[bicycle racer]

some dispensaries test the 3 major cannabinoids now thc cbn and cbd. i would love to cheaply test my strains.

TheNman,

The Cannalytics kit (previously called Cannalyse) you mentioned doesn't work well for measuring THC%.The reason is that such tests with Thin Layer Chromatography (TLC) is not a good way to measure the quantity of cannabinoids. With Gas Chromatography you can and with good accuracy..but you need a lab.

Here is what an experienced member of another site said about TLC :

'' Last issue - about those home test such as Cannalyze -
High-resolution Thin-Layer Chromatography (TLC).
There is no doubt that this system does show the presence of particular cannabinoids in a sample being investigated BUT personally I am far from being convinced that "colorations" left can be used to *quantify* the cannabinoid content of a sample with precision.
I have seen on many magazines results that show varieties having high concentration cocktails of all cannabinoids when tested with cannalyze - then one tests the same sample with GC and finds out it's just another THC dominant variety with TRACES of other cannabinoids.''

Hash containing THC as low as 5-10% is not unheard of ..

Infact most import hash coming from traditional hashmaking countries like Morocco contain under 10% THC , most import hash is around 5% THC. So the big low-THC hash chunk from Aqua is not something with unusually low THC percentage.

Here below is a EU official study chart attached , showing THC % in resin (hash) and herbal cannabis (bud) in various samples from several EU countries.

You can see most hash has a very low THC percentage , usually around 5 or 10%...many times less than herbal cannabis..as bizarre as it may sound..

That 9 bar is pretty typical of what turns up a lot in Europe, in the Uk is gets called 'Soap Bar' cos the bars are the size and shape of a bar of soap, in Spain they call it 'Chocolate'.

The reason it's so low in THC is because it has a lot of contaminants in it, everything from melted down vinyl records to dog shit.

lonewolf99,

I 've smoked import hash many times in different EU countries and the only time I saw crappy soapbar hash was in the UK.. Yes soapbar is less than 10-20% hash , rest is 'other' non-cannabis related stuff..

Most import hash coming from hash exporting countries like Morocco is not cut with crap ..its low in THC not because it has lots of contaminants (..tho it does have some-many contaminants) ..but..because the plants the hash was extracted from were already low in THC. There may be lots of trichs full of resin but the resin doesn't contain high THC %.

Plus the export quality is the 2nd or 3rd grade , the 1st grade kief is kept mostly for local use and the 2nd-3rd grade doesn't contain much THC.

 

[lonewolf99]

I have to disagree, in the last 10 years or so the incidence of contaminated hash has risen a great deal, and not just in the Uk, all over Europe. A lot of soft black hash from India, Pakistan and Nepal is adulterated with cooking oil or ghee, it is said that in Kathmandu these days it is almost impossible to find unadulterated hash and you need to head out to the villages to find the good stuff. The demand outstrips supply so they make up the deficit by cutting the hash with crap, and most smokers aren't informed enough to know the difference.

Hash from Afghanistan, Uzbekistan, Turkmenistan etc is almost always shipepd overland to Europe and this means passing through Russia and former Soviet republics, en route it gets fucked with by the criminal gangs, god knows what they add to it. There are plenty of published reports by the UK Police and Home Office on analyses of this crap.

The best exported Moroccan has lots of THC, so it's not right to say that what the Moroccans export is low in THC, some of it is, but not all of it. Moroccan crops have never been selected for the Bt allele so they have plants that produce THC, some that produce CBD and some that produce both, Moroccan hash can often have quite a lot of CBD in it, which means lower THC levels.

The Moroccans very definitely do adulterate some batches of hash, they aren't responsible for all of the adulteration that goes on, some of it is done in Spain or the UK, but there is plenty of adulterated product coming out of Morocco.

Hi lonewolf ,

If you read my post carefully you 'll see I just said that *I* haven't seen adulterated hash in EU countries apart from UK.. I didn't say there can't be/isn't any.

''Hash from Afghanistan, Uzbekistan, Turkmenistan etc is almost always shipped overland to Europe and this means passing through Russia and former Soviet republics, en route it gets fucked with by the criminal gangs, god knows what they add to it. There are plenty of published reports by the UK Police and Home Office on analyses of this crap.''

I would love to see any report (apart from the UK , which is full of crappy soapbar ), that shows how many of the samples were found to have contaminants. Are you aware of any?

''The best exported Moroccan has lots of THC, so it's not right to say that what the Moroccans export is low in THC, some of it is, but not all of it.''

I didn't say that all exported Moroccan hash is low in THC..., I said most is..and undoubtedly most of it is , theres lots of proof on that by conducted research studies and of course smoke reports.

BTW I have yet to see an analysis with Gas Chromatography that shows exported Moroccan hash with over 15-25%THC...If you think thats not low THC %..what can I say..a good homegrown 'dutch hybrid type' bud has that much THC...

'' Moroccan crops have never been selected for the Bt allele so they have plants that produce THC, some that produce CBD and some that produce both, Moroccan hash can often have quite a lot of CBD in it, which means lower THC levels.''

You are absolutely right about hash from Morocco being made out of a mixture of plants that have different percentages of cannabinoids. Like you said some can have enough THC and very little CBD others have more CBD and traces of THC and there are some exceptions that have enough of both.

So yes using plants with low THC (among plants with higher THC%) is one of the reasons their hash is low in THC .

And thats exactly what I meant when I said that they make hash from low THC plants in my previous post . If they had used only high THC plants they would get hash higher THC..thats pretty obvious.

''The Moroccans very definitely do adulterate some batches of hash, they aren't responsible for all of the adulteration that goes on, some of it is done in Spain or the UK, but there is plenty of adulterated product coming out of Morocco.''

I live in a Mediterranean country so lots of import hash is coming from Morocco (some Afghani as well among other things but these are all rare cases) . I 've personally never seen or smoked adulterated Moroccan hash here so I cant comment much on that. I m not saying that some of the export hash is not cut with crap ..I m sure some is.

Cheers

here in the uk we do get nice hash not just soap bar . the hash in the pic is the best ive seen for the last 10 yrs . atm theres alot of gold and red seal about and meny polms . i have a new polm comming later today will post some pics when i get it .

 

[bicycle racer]

the only hash in europe ive had was at coffeshops in holland but i think that it was made there it was of decent quality. ive heard of soap bar hash thats cut with different things mostly from overseas growers ive also heard of buds being sprayed with i think it was silica crystals also overseas that is really messed up. very bad for you to be smoking. ive also read of beasters from canada but ive not seen that myself i grew up in california and have never run into problems like that not even with mexi brickweed. im almost certain those kinds of products would not be marketable in california its too competitive a market it would not sell.

Analysts at Edinburgh University encouraged by legalise cannabis campaigners and medical users have uncovered some serious potential dangers of smoking the most common "hashish" found in the U.K., SOAP BAR. Even the best of which contains less than 10% psychoactive cannabis.

The findings uncover that soap bars weighing 9oz / 250 grams, on average contain 1/3 oz / 10 grams of flower / resin and up to 200 grams of inert ground-up shade leaf. The remainder consist of c.40 grams of various noxious substances. Using mass spectrometry they found the most common of these are as follows:

Glue
Dyes
Carcinogenic solvents such as Toluene and Benzene (from petrol/turpentine/diesel)
Henna
Pine resin (to mask the smell of the above)
Plastic (often from repressing/remixing bars using petrol/diesel)
Tranquilizers / barbiturates (often veterinary in origin like ketamine) - to stone you

Other ingredients found include;

Tar / bitumen
Wax / Boot polish
Condensed milk powder (burn some…smell familiar ?)
Brick dust / sand (rock burns…)
Digested organic matter / excrement…(it really is shit.)

SOAP is not available from coffee shops in Holland or from farms in Morocco. Bars are often made in Spain or England and can be repressed (and remixed) under heat several times before they get to you. SOAP bar costs about £800 a kilo .SOAP first appeared in the mid 1980's following the loss of Afghan and Lebanese production. Such are the profit levels that the British criminal gangs involved will not import or knowingly "allow" other types of hash into the country and although the price has fallen in real terms since the mid 1980's there are still vast profits to be made from what is serious dilution and adulteration.

If you buy SOAP you are allowing yourself to be ripped off by people who don't give a fuck about you and your health, and are only interested in controlling what they consider to be their market. SOAP is poisonous, it gives real cannabis a bad name, so lets all do ourselves a favour…
