THCA Diamonds: What They Are and How To Make Them

THCA diamonds are one of the most potent cannabis products available. Although not inherently psychotropic, it only takes a little heat to transmute these miniature crystals into THC—the component of cannabis responsible for the high. THCA diamonds are relatively new to the world of cannabis. They rank up there with other high-potency extracts, but exist in a legal gray area because of their chemical structure. Below, we’ll teach you everything you need to know about THCA diamonds. Learn about THCA itself, how to make your own supply of diamonds, and the current legal situation.

What Is THCA?

This might come as a shock to some, but cannabis plants don’t contain THC. Instead, weed flowers produce the chemical precursor to THC, known as tetrahydrocannabinolic acid, or THCA. Enzymes within the buds make this molecule from the "mother cannabinoid" cannabigerolic acid, or CBGA^[1].

Despite their opposing psychotropic status, THCA and THC aren’t all that different. The simple addition of two oxygen atoms and one hydrogen atom prevents THCA from binding to the receptor site that catalyses THC’s psychotropic effects. It only takes a bit of heat to eject these extra atoms—a process called decarboxylation—converting THCA into THC. This occurs when you light the tip of a joint, apply a torch to a bowl, or bake edibles in the oven.

While THCA diamonds and other extracts aren’t psychotropic from the get-go, they quickly become so when exposed to high enough temperatures. This fact has become quite the predicament for several governments, leading to a legal gray area, as you’ll find out below.

Is THCA Legal?

THCA’s close relationship to its psychotropic, decarboxylated version leaves many cannabis users confused. Is it illegal to possess THCA, or only when it’s lit up and turns into THC? It appears regulators haven’t quite figured out the answer to this question yet, either.

Let’s look at the laws in the United Kingdom for example. A fact sheet published by the government states: “THC-A as an isolated substance, in its pure form, would not be controlled under the MDA [Misuse of Drugs Act] 1971 / MDR [Misuse of Drugs Regulations] 2001”^[2].

While this sentence makes pure THCA sound perfectly legal, the document also notes the threshold at which the molecule becomes illegal: “..THC-A will become a controlled substance by virtue of its degradation”.

Things become even more confusing across the Atlantic. The Food and Drug Administration in the United States published a report that details the regulation of cannabis and cannabis-derived products^[3]. Despite mentioning the legal status of cannabinoids such as THC, CBD, and delta-8 THC, the document doesn’t mention THCA once, leaving cannabis users at a dead end.

Despite the apparent blurriness, obtaining THCA involves the possession of cannabis plants to begin with. The US federal government, UK government, and many governments across Europe deem the possession of cannabis illegal. However, importing THCA into countries such as the UK is technically legal, despite the obvious intentions later down the line. As researchers continue to explore the properties of THCA and legislators become more familiar with the constituents, we can expect to see more clear-cut laws emerge.

What Are THCA Diamonds?

THCA diamonds are crystalline structures composed of pure THCA that result from a couple of different extraction methods, including “diamond mining” (more on that below) and the isolation of refined oil.

These techniques essentially separate THCA from other constituents found in cannabis. Even a small diamond can contain more THCA than a blunt full of flower. Cannabis users vaporize or dab THCA diamonds to instantly convert the crystal into a huge amount of THC, resulting in a fast-acting and powerful high.

How To Make THCA Diamonds

You’ve probably collected kief, made some bubble hash, and crafted edibles in the kitchen, so why not try your hand at creating some THCA diamonds? Not only will they deliver one of the strongest highs you’ve ever experienced, but you’ll also make your friends very happy when you show up to a smoking session with these potent crystals.

There are several ways to obtain THCA crystals from cannabis. Flash chromatography is a method used in research settings that involves filtration, rotary evaporation, and purification^[4]. However, you don’t need this fancy equipment if you want to whip up a small batch at home. Instead, you can create pure THCA crystals using a process called diamond mining.

Diamond Mining

Despite its name, diamond mining doesn’t require any pickaxes, shovels, or much manual labor for that matter. While research and industrial operations use advanced equipment for optimal efficiency, you can make THCA diamonds at home relatively easily. However, you’ll need a vacuum chamber and a heat mat to complete the process—worthwhile investments if you plan on doing this frequently.

Ed Rosenthal, otherwise known as the “Guru of Ganja”, has popularised an easy method that anyone can perform at home^[5]. Although he suggests starting out with live resin, BHO extracted from high-quality flowers also works well. Check out the simple steps below to craft THCA diamonds at home.

What About CBD Crystals?

CBD enjoys a much more liberal legal status in many countries. Manufacturers are able to make large quantities of CBD diamonds boasting a purity of 99%. This crystalline CBD can then be used in all sorts of applications, such as making CBD oil. Although they lack the beneficial synergy of additional terpenes, users can also add CBD diamonds to bong bowls alongside dried flowers and concentrates.

How To Use THCA Diamonds

Vaping and dabbing are two of the most popular ways to consume THCA diamonds. The highly concentrated levels of THCA offer a powerful high following the application of heat. You can sprinkle them into vape chambers alongside flowers and concentrates. If you leave them combined with the terp sauce, prepare to experience some intense flavors!

How Much Are THCA Diamonds Worth?

THCA diamonds clock in at around five times the potency of standard buds, a trait that gives them a hefty price tag. They cost around $60 per gram in US dispensaries, and remain rare elsewhere.

DisclaimerExtracts, concentrates, and oils used for dabbing are among the strongest cannabis products available. Proceed with caution when using substances high in THC. Start with low doses and slowly increase over time to build up a tolerance to the compound.

Remember: Set and Setting will help you deal with various situations.

Stay Cultivated.
