Most of us think of THC as the compound of the cannabis plant that helps you relax, take the edge off, or get high.

That’s not entirely true. Learning about different forms of THC can answer questions you have about flower and vape products you come across as a cannabis user.

Throughout this guide, we’ll focus on tetrahydrocannabinolic acid (THCa) and Delta-8 THC, breaking down their differences, similarities, and benefits.

We’ll introduce you to some Mood products that feature THCa and Delta-8 THC and hopefully help you discover some new cannabis products and find your happy place.

THCa vs. Delta-8 THC

An Introduction To THCa

Short for “tetrahydrocannabinol acid,” THCa is THC in its acidic form. It’s also the form of THC most commonly found in raw cannabis plants.

Derived from cannabigerolic acid (CBGa), tetrahydrocannabinolic acid (THCa) also possesses an evolutionary ability that makes it stand out.

Unlike THC, the effects of THCa on its own are non-psychoactive. The acidic cannabinoid does, however, become more potent when heated or smoked.

Where Delta-8 THC Comes From

D8 THC is another cannabinoid, but unlike THCa, it does not occur in large amounts in the hemp plants in their raw form.

D8 THC is used in higher concentrations for cannabis plant products like flowers, concentrates, and edibles.

For these uses, it’s derived from either CBD or Delta-9 THC, which is a product of THCa.

D8 THC has a reputation for delivering a clear and focused high that might not feel as intense as one brought on by consuming Delta-9 THC. Because of its slightly more mellow effect, D8 THC serves as a choice for cannabis enthusiasts looking for a lighter experience.

What THCa and Delta-8 THC Have In Common

Before we get into the key differences between these cannabinoids, it’s worth explaining what they have in common.

The Agricultural Improvement Act of 2018 (also known as the Farm Bill) removed hemp from the federal government’s list of controlled substances.

A key metric from that bill defined hemp as a dry cannabis product containing no more than 0.3 percent of Delta-9 THC.

THCa and D8 THC, on the other hand, can exist at any concentration in a harvested dry cannabis product while maintaining its federally legal status as hemp.

Depending on state laws, this offers cannabis users an avenue to enjoy the psychoactive effects of D8 THC legally and to purchase THCa products that will become more potent when smoked or vaped.

While united in their proximity to Delta-9 THC and mutual legality, these two cannabinoids have more than a few key differences that we’re going to break down here.

THCa vs Delta-8 THC: Five Main Differences

1. Psychoactive Properties

Delta-8 THC

Despite being permissible at any concentration under federal law, D8 THC is still a psychoactive cannabis compound.

As we touched on earlier, the high associated with D8 THC is better suited for those whose desired effects are more toned-down from what you might expect out of Delta-9 THC.

THCa

As an acidic precursor to THC, THCa doesn’t possess any psychoactive properties in raw cannabis. When you smoke it or vape it, the THCa converts to a more potent form.

2. Chemical Structure

THCa and D8 THC are both cannabinoids that exist with a wealth of others found in fresh cannabis plants.

THCa

As a non-psychoactive precursor to Delta-9 THC, which can be a precursor to D8 THC — THCa differs because it has an extra carboxyl group.

It’s not proven exactly why THCa on its own isn’t a psychoactive cannabinoid, but a common belief is that the cannabinoid acids it contains prevent it from bonding with CB1 and CB2 receptors in the brain.

Delta-8 THC

Without the carboxyl ring maintained by THCa, D8 THC is a more simple cannabinoid.

It’s closer to Delta-9 THC. The only difference is that on the chain of carbon atoms making up a D8 THC compound, you can find a double bond on the eight carbon. With Delta-9 THC, you can find a double bond on the ninth carbon.

Its slightly varied chemical structure distinguishes D8 THC from the more popular Delta-9 and is potentially responsible for its more mellow effects.

3. Consumption Methods

Looking at THCa vs Delta-8 THC, you might see appeal in experimenting with both.

Here are some of the different types of hemp-derived products they’re used for and where to find them:

Smokeable and Vapeable THCa and Delta-8 THC

You can enjoy psychoactive effects when you consume THCa products that will become more potent upon burning.

These products include your classic cannabis flower, pre-rolls, cannabis extracts, and concentrates — i.e. THCa diamonds — and disposable vapes.

4. Reputation and Popularity

While THCa and Delta-8 THC are unknown to many cannabis users and seemingly indistinguishable, they’re also clearly unique in their own rights.

In terms of how the world of cannabis views these cannabinoids, there seems to be slight variation in how they are approached based on their legality and psychoactive effects.

THCa: A Legal Avenue To Consuming Enjoying THC

Because of TCHa’s ability to increase potency with heat, it exists as a legal resource for cannabis enthusiasts who love THC levels and highs they’re used to.

THCa products qualify as hemp according to the Farm Bill, which removed hemp from the federal government's list of controlled substances, which means you can order them and hemp products rich in other cannabinoids online and straight to your doorstep.

Delta-8 THC: A True Delta-9 THC Alternative

Also legal in any concentration, Delta-8 THC is another one of those hemp-derived cannabinoids that's technically different than Delta-9 THC.

For seasoned cannabis users and new ones, choosing this slightly more mellow cannabinoid might better suit your taste.

You can also legally buy highly concentrated Delta-8 THC products legally for more potent and recognizable effects.
