THC Content has Increased 5X in Cannabis Since 2000

Not sure if this applies to Thailand cannabis ... 

 

But a brain researcher warning about cannabis here ..

This brain researcher warns that daily use of cannabis or use of high potency cannabis can cause serious problems

Sometimes this Thai weed hits me like Acid or mushrooms.

As much as I tried before having bong after huge bong I could never get as high as on this current stuff.

 

They really have done an excellent job improving it so much.

Like forgetting where I put my keys.

Sometimes I walk to another room and by the time I get there I have forgotten why I did. 

Also I find it hard recognizing Thai people and where I know them from. They sort of all look the same anyway but after a puff I can’t remember who is who or even if I know them. Luckily I just give them a smile which works ok in the Land of Smiles.

It would be hard to pull it off in Russia

Like so many things, this too is being ruined by the overzealous user/grower. Where years ago you could smoke a joint, get a healthy fit of laughter, feel completely relaxed, and then enjoy a good meal and sleep, the stuff nowadays has been bred to such extremes that it completely knocks you out of this world. I can imagine this leads to many problems, putting the legitimacy of the substance under pressure, turning public opinion against it, and forcing governments to step in by enforcing stricter regulations or even a total ban.

Would never have thought that 😁 try explaining that to the users

[bamnutsak]

Incorrect, or at the very least inaccurate and uninformed.

 

Makes folks who repost this sort of fake research look very stoopid.

 

Cannabis, very generally speaking - and I refer to flower not extract-related products, which get up to 90% THC - has been in the 20% THC range for three or more decades.

 

And most folks just smoke less to achieve the same high.

 

I mean you don't drink the same amounts of spirits as wine or beer do you?

It's already been legalized, so not sure why any scientist would make up that THC content has increased and they are seeing higher incidents of szhizophrenia.

 

Maybe some users who have been smoking it for decades will adjust the amounts, but maybe new users have no point of comparison.

 

If it's fake research, then I do apologize. There's no way for me to know if it's fake or not.

Maybe it's age, but I can remember it being just perfect for going to concerts and live bands... and then afterwards, 2am in some persons garage always with a sofa, black-lights, chilling, listening to tunes, drinking and playing cards.

You can find sativa-dominant strains which allow for more focus, energy, clear-headedness, and with lower THC content, 15% - 20 %.

 

And you can smoke less, I'd submit that makes it healthier as you are consuming less burned plant matter in your throat and lungs.

 

If I drink 2 pints of ale, that doesn't mean I'm going to drink two pints of wine, or two pints of vodka. After an experience or two we learn to regulate. Same same for cannabis.

This is a bit off-topic, but another post from the same Dr.

 

Should we be taking Psylicybin instead of smoking weed?

 

What's all that red and green?

Away, Away With Weed - Indeed, The Song Of Reefer Madness
(sung to The Song Of The Temperance Union)

We're marching, we're marching, our staunch little crew,
Against that green ganja, we know what to do.
No spliffs or no reefer, we stand up and shout,
It fries up your brain and it burns your cash out!

Away, away with weed - indeed,
With weed - indeed, with weed - indeed,
Away, away with weed - indeed,
The song of Reefer Madness!

We shun Mary Jane, like we shun ugly bugs,
One little puff turns a man to a slug!
Oh, picture the shame of a stoner’s sad fate,
Sprawled out on the couch with some chips on his plate!

Away, away with weed - indeed,
With weed - indeed, with weed - indeed,
Away, away with weed - indeed,
The song of Reefer Madness!

No bongs and no blunts, they just cloud up your mind,
They make you see visions of the silliest kind.
Oh, dodge that dank haze, it’s a devilish trap,
You’ll giggle, then stumble, and land in a nap!

Away, away with weed - indeed,
With weed - indeed, with weed - indeed,
Away, away with weed - indeed,
The song of Reefer Madness!

No kush and no chronic, they lead to despair,
Your morals will tumble, your soul left threadbare.
It drags you to ruin, that devilish green,
So join our crusade, keep your conscience serene!

Away, away with weed - indeed,
With weed - indeed, with weed - indeed,
Away, away with weed - indeed,
The song of Reefer Madness!

So rise up, good people, and fight the good fight,
No pot, no more toking, we’ll stand for what’s right!
No spliffs, no more reefer, no haze to consume,
With the Temperance Union, we’ll banish the fume!

Doubt there's anything in Thailand over 16%

 

If you look at the testing report it says 16% and 17% in two different tests, but the shop adds the two tests together and advertise it as 32%.

 

Nothing has changed except the marketing.

Certainly not the effect on me.

There is, but it's expensive. I come from California where weed has been legal medically and then recreationally since the '90's so I know what good weed is. I smoked some 600 baht a gram flower from a Pattaya dispensary, it was true 2 hit sh*t, must have been about 30% thc, so it's around if you want to pay for it.

[Ben-hh]

THC % + THCA% multiplied usually by 0.877 = total THC

Plenty of 1-2 hit chronic stuff around in the 30 Baht range when bought in bulk. Averaging around 25% THC, give or take. You won't find any of it online though being sold by those sellers who are selling that cheap eVap stuff. If you go to those dispensaries in the tourist zones you will always grossly over pay too and it's not necessarily any better.

The stronger the better in my view. The less you need to consume, the less wear and tear on your own body. I don’t think any of it is too strong, it all comes down to dosing. People naturally build up a tolerance over time and eventually need more to get the same effect, so stronger just means they will still need smaller amounts even as tolerance grows.
 

Most of the bulk contraband stuff around in the eighties, mainly from Mexico and South America, was so weak it probably did more harm than good. Most of it didn't smell or taste good, was very dry and harsh, and who knows about the growing conditions.
 

The quality now is far better with a lot of it grown indoors without pesticides. You've now got a world with nearly 50 years more growing experience since the 80s, and with lots of great new hybrid strains, so I would argue that what you get now is actually far superior and safer to when it was 5X weaker.

The correlation is with adolescents NOT adults. It is a contributory factor towards psychosis spectrum disorders, not the only factor. Dr. Fabiano did not do the studies but correlated metadata. The medical science community understands that correlation is NOT causation.

There absolutely Is. Do the research without Google, YouTube or social media reposts. ChatGPT is also not accurate unless you tailor your search to peer reviewed science and medical journals. The reported research on this topic however, is not fake.

Cannabis in all its forms, recreationally and medically, is NOT genetically engineered. Not even close, though it is coming. It has been heavily hybridized and crossed but it is not GMO.

Another widely disproven weed shop myth. The lines between Indica (down) and Sativa (up) have been irreparably blurred through hybridization. For all you disbelievers holding on to this myth, PM me for the Dr. Ethan Russo paper (interview). He is one of the progenitors who settled this.

yes, there is a lot of such science.

also, maybe mostly relates to teens as they are more susceptible to negative influences of weed.

Hash back in the early 90s was still far stronger than today's flower.

Thanks for always dropping straight knowledge.

[zzzzz]

looking back over the years 
The Mexican of the 60's was i guess around 6-8%, thai stick of the 70's 12-15%

Morrocan hash of the 70,80' 90's 18-22%%,  Manali 25-30%, Nepali 20-22%
Crap brick weed here in Thailand (remember the red string crap?  of the 2000- 2010's) 6-8%
Dark web hash/weed 2012- 2 hit ur speechless 25-35%  
I have only bought once via a dispensary here and that was 200 baht/ and around 15%-18%

I am very happy with my 10 baht/grm online at i figure, 12-15% even thou they say 22%

to say its increased 5x is pure BS

and thats that  🙂

I was there, just had to get an easily obtainable doctors rec to buy weed in the '90's in California.

 

You calling me a liar?

I would seriously doubt the validity of this test. To have THC and THCa to be nearly equal suggests a spurious result. The majority of THC in flower exists in the acid, non-decarboxylated form. To have THC and THCa almost equal is a red flag. Industry testing averages show a cannabinoid ratio of 80:20 (THCa to THC) so the report is flawed, for certain.

 

Unless 50% of the THCa has miraculously converted to D9-THC through time/temperature decarboxylation, naturally, the test implies a huge error. Also, note CBG is at 4.4% a HUGE number that suggests unconverted THC/THCa has been left “on the table” - harvesting too early. The test, in and of itself, is a red flag.

 

And, yes, as mentioned by a previous poster, you do not add THC+THCa to come up with total THC%.  13% of the total THCa is lost to conversion (decarboxylation) - the weight of the CO2 molecule removed (COO). Tot THC = THC + (THCa * .877).

 

Though LightLab3 uses HPLC protocol, the margin of error is greatly increased by sample preparation and human error. We have seen huge margins of error in the brick and mortar labs we have used in Bangkok as well. Lab shopping in the USA to prop your numbers is a known thing, I can just imagine how the numbers will be “cooked”, here in Thailand.

 

As a closing salvo, current research shows, industry average THC% around 15% in legal rec/med markets. As I like to say, the two biggest lies in the cannabis space are: name of strain and reported THC %.
