THC Products
Welcome to the ultimate destination for premium THCa products in the United States. ILGM is proud to partner with United Strains of America to bring you a comprehensive collection of lab-tested, high-potency THCa offerings that set new standards for quality and consistency. Whether you're a seasoned connoisseur or new to THCa, our curated selection has something exceptional waiting for you.
THCa is the raw form of THC found naturally in the cannabis plant, and it's become one of the most sought-after hemp-derived products in the US. Unlike THC, THCa is non-psychoactive on its own. Heat it up, and it converts. That's why the flower, vapes, and pre-rolls on this page can deliver a full cannabis experience while staying federally compliant under the 2018 Farm Bill.
Everything here is sourced from United Strains of America (USOA), a premium hemp brand with a strict commitment to domestic cultivation and third-party lab testing. If you've grown cannabis with ILGM seeds, you already know what quality looks like. These products hold the same standard.
What Is THCa and How Does It Work?
Before you buy, it helps to know exactly what you're getting, and why it's legal.
THCa vs. THC: What's the Difference?
THCA (tetrahydrocannabinolic acid) is the acidic precursor to THC. In raw cannabis, almost all the THC content exists in this form. The conversion happens through decarboxylation, the process of applying heat. When you smoke, vape, or combust THCa flower, that heat triggers the reaction and produces the THC responsible for cannabis' effects.
This distinction matters for how these products are regulated. In their raw state, hemp-derived THCa products contain less than 0.3% delta-9 THC by dry weight, putting them within the federal definition of hemp under the 2018 Farm Bill.
Is THCa Legal?
Federally, yes. Hemp-derived THCa products that meet the 0.3% delta-9 THC threshold are legal under the 2018 Farm Bill, a position further acknowledged by the DEA in 2022. State laws vary, though, and some jurisdictions impose additional restrictions. Check your local regulations before ordering.
Every USOA product sold on this page comes with a certificate of analysis (COA) from a third-party lab, confirming both potency and compliance.
Explore ILGM THCa Products
Our catalog covers every format worth having. Flower for the full experience, vapes for convenience and concentration, pre-rolls for when you don't want to think about it, and bundles for when you want more of what works.
THCa Flower
THCa flower is cultivated hemp grown to the same standard as cannabis—the same look, the same smell, the same terpene-rich buds. Potency levels vary by strain, with most in the 25–39% THCa range. The selection covers indica, sativa, and hybrid options, so you can match the experience to the time of day or the mood you're after.
Live Rosin THCa Vapes
Live rosin is a solventless concentrate made from fresh-frozen plant material, preserving the terpene profile that chemical extraction methods can strip away. The vapes in this collection reach up to 89%+ THCa and come in 1G cartridges across a range of strain profiles. For anyone who wants potency without the prep, this is the format.
THCa Pre-Rolls
Pre-rolls are machine-rolled with the same flower available in the loose flower category—ground, packed, and ready. Available in 1G and 1.5G sizes across multiple strains. No grinder, no papers, no extra steps.
THCa Bundles
Bundles group compatible products at a 15% discount off the individual price. Options range from strain-specific flower bundles to curated vape packs and mixed-format sets. A practical way to try more at a lower cost per item.
What Makes ILGM THCa Products Unique?
Curated, Not Just Listed
ILGM doesn't stock every brand that lands in an inbox. The USOA partnership was chosen because their quality controls align with what ILGM has always applied to genetics: lab-verified, source-traceable, and consistent across batches. Every product goes through third-party testing before it reaches the catalog.
Strain Familiarity for Growers
Many strains in the USOA catalog are ones ILGM customers have grown themselves. That's not a coincidence. Growers who've spent weeks dialing in a Gelato or a Sour Diesel have a different relationship with those names than a casual buyer does. The THCa category is built partly with that customer in mind.
COA Transparency
Certificates of analysis are available for every product. They confirm THCa potency, verify delta-9 THC compliance, and screen for residual solvents and contaminants. If you want to see what you're buying before you buy it, that information is there.
Powered by United Strains of America
Every product in this catalog comes from one source. Here's why that source matters.
Who Is USOA?
United Strains of America is a hemp brand based in Fort Lauderdale, Florida, founded on the premise that federally legal THCa products should meet the same quality bar as regulated cannabis. Their catalog covers flower, vapes, pre-rolls, and bundles, all grown domestically and tested batch by batch.
USOA has been featured in several major cannabis publications and has built a customer base around one thing: consistent, lab-verified products delivered with discretion. Their tagline is "Born free, smoked proud," and the ethos behind it is straightforward: quality without compromise, available to every legal-age adult in the US.
Grown and Tested in the USA
All USOA flower is domestically cultivated. Third-party testing isn't an afterthought, it's part of the standard process for every product batch. COAs cover potency, terpene profiles, and contaminant screening. That documentation is publicly accessible and tied to specific lots, not just a general brand claim.
Discreet by Default
Every USOA order ships in plain, unmarked packaging with no reference to the contents. Stealth shipping is standard, no opt-in required.

THCa Products: Frequently Asked Questions
Is THCa the same as THC?
Structurally similar, but not the same compound. THCa won't produce intoxicating effects unless it's heated: smoked, vaped, or otherwise combusted. In raw form, it stays non-psychoactive.
Will THCa products show up on a drug test?
Almost certainly yes. Because THCa converts to THC through metabolic processes in the body, standard drug tests are unlikely to distinguish between the two. If drug testing is a concern, consult a healthcare professional before use.
What's the difference between THCa flower and CBD flower?
THCa converts to intoxicating THC when heated. CBD does not produce intoxicating effects regardless of how it's consumed. These are distinct cannabinoids with different effects.
What is live rosin, and why does it matter?
Live rosin is a solventless concentrate produced from fresh-frozen plant material. Because no chemical solvents are used, the terpene profile is preserved more completely than in most other extraction methods. It's considered a premium format for that reason.
How should I store THCa flower?
Store in an airtight container, away from direct light and heat. Humidity control packs help maintain freshness and prevent the kind of moisture buildup that degrades terpenes over time.
