Is THCa just cannabis in disguise?

Hemp-derived legal highs, such as Delta 8 and HHC, continue to explode in popularity, but many people are unaware that can now buy cannabis legally online through yet another legal loophole.

It’s called THCa flower and it will get you as high as a kite, just like regular high-THC cannabis.

So, what is high THCa hemp flower and how is it that you can buy THCa flower online? In this article, we’re going to explain what THCa flower is and then tell you where you can buy the best THCa strains.

What is high THCa flower?

If you see THCa flower for sale, what you’re essentially looking at are cannabis buds marketed as hemp. To be classified as hemp, the flower needs to contain 0.3% or less of the compound Delta-9 THC, so as long as the actual D9 THC level is compliant, vendors can technically sell THCa flower as hemp.

This cannabis-ish distinction gets especially murky for hemp flower when the buds contain percentages of +15% THCa. Flower with high percentages of THCa could easily be sold in cannabis dispensaries and pass for weed.

Hemp or cannabis?


THCa stands for tetrahydrocannabinolic acid. It is the acidic precursor to THC, meaning that it’s produced in the resinous glands of cannabis flowers before THC, so THC cannot physically exist without THCa. CBD also comes from an acidic precursor called CBDa, CBG comes from CBGa, and so on.

These acidic compounds haven’t had a lot of research carried out on them just yet, so we know very little about their potential therapeutic benefits, but the little we do know is already very promising. Preclinical studies have shown that CBDa and CBGa may be able to prevent the Covid-19 virus from entering and infecting human cells (more on that in my article here).

THCa has already demonstrated potent antiemetic, anti-inflammatory, and neuroprotective properties, but the vast majority of people who are buying THCa flower are not looking to benefit from the anti-inflammatory effects of the compound. Instead, they’re usually buying it for the intoxicating effects of THC.

Does THCa flower get you high?

If you consume THCa flower raw (unheated) then you’ll be ingesting pure THCa which won’t get you high. But flower will get you high if you smoke it, vape it, or decarboxylate it before consumption (just like regular cannabis).

You see, THCa turns into THC when you apply heat, through a process called decarboxylation. Current estimations say that around 87.7% of the THCa in flower will be converted into Delta-9 THC when you heat it, which of course happens automatically when you either smoke it.

THC vs THCa in flower

So, you may be wondering what the difference is between THC flower and THCa flower?

And the answer is that there really is no difference. What we know and refer to as high-THC flower is in fact high-THCa flower. They are one and the same, but in order to be classified as hemp the flower must contain no more than 0.3% Delta 9 THC, whereas true cannabis flower could have slightly more than this.

Cannabis labelling

Take a look at the sticker below that comes on cannabis flower from a dispensary in Washington state. This sticker is known as the “variable data sticker” and it contains all the legally necessary information that changes from harvest to harvest.

The sticker is printed out and put on top of the branded cannabis packaging to show consumers exactly what they are getting when they purchases the product.

Notice how the THC percentage is 0.80% which puts the product under the cannabis classification. The THCa percentage on the other hand is 25.91% meaning that smoking the flower will get you super stoned.

And below are lab results from a cannabis strain sold in the California recreational market.

Now let’s take a look at the lab result of a high THCa hemp strain.

Notice how the Delta-9 THC (Δ-9 THC) is below .3% which legally classifies the flower as hemp. The THCa on the other hand is over 21% which translates into a seriously psychoactive high.

Yes, THCa flower is legal across most of the USA. As long as that Delta 9 THC level remains compliant (under 0.3% dry weight), then THCa flower does technically fall under the hemp category, making it fully legal at the federal level.

In a letter sent at the beginning of last year (January 2022), Terrence L Boos from the DEA said “material that is derived or extracted from the cannabis plant such as tissue culture and any other genetic material that has a delta-9 tetrahydrocannabinol concentration of no more than 0.3 percent on a dry weight basis meets the legal definition of “hemp” and is thus not controlled under the CSA [Controlled Substances Act].

Pretty crazy, right?

So is this good or bad?

We at CBD Incubator think that it’s a great thing that as many people as possible get access to cannabis and this is 100% a step in the right direction!

However, remember that the current legal framework is being “bent” and that could result in stricter laws that end up holding back proper federal legalization of cannabis.

Best high THCa hemp flower strains

If you’re looking to get legally high from smoking your hemp flower then I recommend ditching the Delta 8 flower (which I’ve always thought was harsh to smoke and often not clean) and instead, look for high THCa hemp strains.

As always, we’ve done the research for you, so here are the #7 best THCa flower online right now to get you high as a kite 🪁

1. Death Star

Death Star High THCa Hemp Flower

With 23% THCa (over 20% THC after decarb), Death Star is my favorite THCa strain at the moment. It smells and tastes amazing and as an indica dominant hybrid, I was surprised to find that this strain is strangely energizing for me.

I really love the way it makes me feel – which is incredibly high, but super motivated and positive. The dense nugs weigh pretty heavy though so the 3.5 gram baggy feels a bit on the small side when you open it up.

2. Green Crack

Green Crack High THCa Hemp Flower

I love Green Crack! It is a balanced sativa strain witt 21% THCa (18% THC after decarb). It’s not as strong as Death Star on paper, but I don’t think you’ll notice the 2% difference because the great terpene profile makes Green Crack a super heavy hitter with a pungent gassy nose.

3. Hippie Crippler

Hippie Crippler High THCa Hemp Flower

Hippie Crippler’s buds are smaller and stickier than many other strains you’ll come across, making it a little trickier to roll with, but once you inhale that amazing aroma you’ll realize it’s worth it. At just under 20% THCa, the sativa dominant Hippie Crippler delivers over 17% THC.

Contrary to what the numbers say, I found this strain to be too debilitating for daytime use (perhaps I took bigger puffs? I don’t know) but it sure was fun.

4. Miracle Alien Cookies

Miracle Alien Cookies High THCa Hemp Flower

Miracle Alien Cookies THCa flower is a 50/50 hybrid that delivers 20% THCa, so around the same THC as Hippie Crippler. It has a particularly delicious and complex flavor, both sweet and spicy, and it delivers a lovely all over body relaxation that is great for Netflix and chilling.

5. Mocha

Mocha THCa flower

Mocha has around 20% THCa and a wonderful terpene profile with tropical flavors and uplifting “haze” type effects. I enjoy this strain in the morning for days when I don’t need to work or leave my apartment.

It does have pretty strong effects and fills me with energy but it gave me moments where I just stared into empty space, forgot what I was doing and made silly mistakes. I guess that’s what it means when labels say “don’t operate heavy machinery” 🤷‍♀️

6. Blueberry

Blueberry High THCa Hemp Flower

Not to be confused with Blueberry Muffin, which is a CBD flower strain, there are two different versions of this high THCa Blueberry strain making the rounds at the moment, pheno #1 (or green pheno) and pheno #2 (purple hue pheno). If you’re attracted to this strain from the name then you should choose pheno #1 as pheno #2 is more gassy and creamy rather than blueberry.

With 22% THCa (20% THC), this indica dominant strain will have most experienced cannabis users on their ass after one joint.

7. Gorilla Glue #4

Gorilla Glue High THCa Hemp Flower

If you want to get your hands on one of the strongest THCa flower strains around at the moment, then both Arete Hemp and WNC CBD can hook you up (if they have any left). I certainly can’t wait to try it!

8. Platinum OG

Platinum OG

Platinum OG is one of the strongest THCa strains around at the moment with 23.91% THCa (which will decarb to around 21.18% THC), as well as 1.73% CBG. This earthy and herbal tasting strain is an indica-dominant hybrid (75/25) that provides an intense physical high which will melt your limbs to the couch within just a couple of hits.

Alongside the body high, Platinum OG is also fantastic for calming and numbing your mind, so I recommend readying yourself for bed before lighting up that joint.

High THCa flower for symptom relief

It’s worth noting that the seven strains listed above are hemp flower strains with THCa, not CBD flower strains with THCa. They’re not classed as CBD flower strains because none of the strains above actually contain detectable levels of CBD.

We all know by now that THC has a number of therapeutic uses, but it also helps to enhance the medicinal benefits of CBD in a phenomenon called the entourage effect.

So, if you’re interested in using high THCa flower for symptom relief, then you might want to combine it with CBD for the best effects. Some medicinal users don’t appreciate the level of intoxication that’s caused by THC and CBD can help reduce this too. Some users can get quite sever paranoid when smoking pure THCa buds so you may want to consider mixing in CBD flower to make the experience less intense.

One option is to buy some high THCa flower online and mix it with some CBD flower before you smoke or vape it. If it’s your first time experimenting with THCa flower, then I recommend you start with a very small amount and gradually increase it as you get used to how it makes you feel.

The other option is to look for CBD flower with high THCa levels. A strain like Unicorn Butter (available from WNC CBD) has 12% CBD and nearly 2% THCa so it’s not designed to get you super high but instead offer more enhanced symptom relief.

Where can I buy THCa hemp flower?

If you’re looking for high THCa hemp flower for sale, I highly recommend you check out Arete Hemp and WNC CBD. Both brands are highly respected in the hemp flower space and have sought legal advice before selling their high THCa flower strains (published online).

At the time of writing, both companies had all six of these high THCa flower strains in stock, but several of them are limited edition strains and are bound to sell out quickly (so get them while you can!).

UPDATE: Secret Nature has also just added a fantastic selection of high THCA hemp flower strains to their menu! I can’t wait to try them 🥳

ANOTHER UPDATE: Binoid has also just launched their own line of flower under the brand name, “Bloomz“. They already have seven awesome high THCa strains on their menu, as well as THC-O, HHC, and Delta 8 flower.

Both Arete Hemp and WNC CBD also sell THCa diamonds (aka crystals), which are highly potent concentrates. I would only recommend these for the more experienced THC users out there. If Delta 8 isn’t strong enough for you and you enjoy getting as high as possible, then you’re going to fall in love with these bad boys.

Bloomz sister company, Binoid, also has a great selection of THCa carts and disposables for all you vaping enthusiasts.

Buy THCa flower while you still can!

No-one knows what the future of high THCa hemp flower holds, so if you love getting high, are curious about it, or are seeking more effective symptom relief, then I seriously recommend you buy some THCa flower now while you still can.

THCa flower for sale

Arete Hemp, Bloomz, WNC CBD, and Secret Nature are allowing you to buy premium quality, legal hemp flower that will get you high af – at least a high as any self-respecting THC cannabis flower from a dispensary might. I’ve tried THCa flower from a number of different vendors now, but these are my favorites.

Good luck and enjoy.
