THCA vs THCP: What They Don’t Tell You About These Two Cannabinoids

THCA vs THCP

May 5, 2025Guide

Let’s be honest. The cannabis world moves fast. Every time you blink, there’s a new cannabinoid everyone’s talking about. Lately, two of the buzziest names floating around are THCA and THCP.

Now, if you’ve seen them listed on vape carts, edibles, or tinctures and thought, “What’s the difference and which one’s for me?” You’re not alone.

This guide breaks it all down without the fluff. Whether you’re a seasoned stoner, a medical user, or just plain curious, you’ll walk away knowing exactly what THCA and THCP are, how they compare, and what to watch out for.

Quick Summary (for the Skimmers)

Psychoactive? Nope (until heated) Extremely yes
Potency Converts to THC (moderate) Up to 33x more potent than THC
Found in Raw cannabis Tiny amounts naturally; mostly lab-made
Great for Inflammation, nausea, general wellness Intense euphoria, strong pain relief
Best used by Wellness-focused or THC-sensitive folks Experienced users only
Legality Federally legal if under 0.3% THC Also legal under Farm Bill, but sketchy in some states
Forms Juices, tinctures, raw flower Vapes, dabs, potent edibles

First Things First: What Exactly Is THCA?

THCA stands for tetrahydrocannabinolic acid. It’s basically the raw version of THC, the stuff that gets you high. But THCA itself? Totally non-psychoactive.

You’ll find THCA in raw, unheated cannabis. The second you light it up or apply heat (aka decarboxylation), it transforms into THC, the compound that gives you that classic cannabis buzz.

Why Does That Matter?

Because some people want the benefits of cannabis like reducing inflammation or nausea without the high. And that’s where THCA shines.

Okay, So What’s THCP Then?

This one’s wild.

THCP (tetrahydrocannabiphorol) was only discovered in 2019 by Italian researchers, but it’s already making a name for itself and not just because the name is hard to pronounce.

Here’s the kicker: THCP is believed to be up to 33 times more potent than THC. Not 30%. Thirty-three times.

How?

It all comes down to its molecular structure. Without getting too nerdy, THCP has a seven-carbon side chain, while THC only has five. That longer chain lets it bind to CB1 receptors in your brain much more effectively hence the intense effects.

People report feeling incredibly stoned, deeply relaxed, euphoric, and sometimes overwhelmed if they take too much. So tread carefully.

Let’s Get Nerdy for a Minute: Structure & Science

Why does THCA not get you high, but THCP can knock you on your ass? It’s all chemistry:

  • THCA has a carboxylic acid group that blocks it from binding to your CB1 receptors. Once you heat it up and remove that group, you’re left with THC.

  • THCP has the same backbone as THC, but with a longer alkyl side chain. That chain makes it stick to your receptors like glue.

So while THCA is like an athlete waiting on the bench (until decarbed), THCP is already sprinting on the field and running circles around regular THC.

Effects Comparison: What You Might Actually Feel

Let’s talk real-world experience. Here’s what people commonly report:

THCA (raw or minimally heated)

  • Clear-headed

  • Reduced inflammation

  • Less joint pain

  • Milder stomach or nausea symptoms

  • Not “stoned,” just generally better

THCP

  • Intense euphoria

  • Deep body relaxation

  • Altered sense of time

  • Visual distortion

  • Extreme couch-lock (aka: cancel your plans)

Bottom line: THCA feels more like a supplement, while THCP is a sledgehammer meant only for users who know their limits.

Safety and Side Effects

THCA

Most people tolerate THCA well, especially in its raw form. Side effects are rare but may include:

  • Mild dizziness (if converted to THC)

  • Dry mouth

  • Headache (in rare cases)

THCP

Because of its insane potency, you really want to be cautious here. Possible side effects:

  • Anxiety or panic attacks (especially at high doses)

  • Intense sedation

  • Increased heart rate

  • Confusion or paranoia

  • Overwhelming high that lasts hours

Start low. Way low. Then wait.

Product Types: What You’ll Actually Find Online or In Stores

THCA

  • Raw flower (not decarbed) – You can juice it or use it in cold tinctures.

  • Live resin diamonds – High-THCA content that converts to THC when dabbed.

  • Capsules or tinctures – Ideal for wellness users avoiding THC.

THCP

  • Vape cartridges – Most common form.

  • Potent edibles – Gummies, chocolates, etc. Start with microdoses.

  • Concentrates/dabs – Only for pros.

  • THCP blends – Often mixed with delta-8 or HHC to mellow it out.

Be wary of fake or under-tested THCP products. Ask for third-party lab results when buying anything potent.

Legality: Is This Stuff Actually Legal?

Thanks to the 2018 Farm Bill, hemp-derived cannabinoids are legal federally as long as they contain less than 0.3% delta-9 THC by dry weight. That loophole has allowed a lot of stuff to hit the market.

THCA

  • Federally legal if the product’s total THC content (after heating) is under 0.3%.

  • BUT some states now test based on “potential THC,” meaning THCA gets counted toward the limit.

THCP

  • Technically legal if derived from hemp and the THC level is compliant.

  • BUT the DEA is starting to look more closely at “synthetically produced” cannabinoids like THCP.

  • State laws vary a lot. It’s legal in most states right now, but that could change fast.

Always check your state laws.

Bioavailability: How Your Body Absorbs Each

  • THCA is usually consumed orally or topically, which offers mild effects and lower absorption rates. If heated, it becomes THC and behaves like regular weed.

  • THCP, especially when vaped or dabbed, hits fast and hard. It also binds more tightly to receptors, so the effects feel stronger and last longer.

The Entourage Effect: Playing Well with Others

Both cannabinoids interact with the endocannabinoid system, but they do so in different ways.

  • THCA pairs well with CBD, CBDA, and terpenes like limonene or myrcene for full-body wellness.

  • THCP is usually combined with milder cannabinoids like delta-8 or CBN to balance out the intensity.

If you’re looking for a more well-rounded effect, don’t rely on THCP alone it’s more of a solo act unless formulated right.

Storage, Shelf Life & Lab Testing

  • THCA is stable in cool, dark places, but heating or time can convert it to THC.

  • THCP is pretty stable but being new, its long-term shelf life is still under research.

Lab Testing Tip

Testing THCP is tricky. Some labs still don’t test for it properly, and mislabeling is common. Always buy from brands that show:

  • Full-panel COAs (Certificates of Analysis)

  • Batch-specific potency breakdowns

  • Third-party verification

Final Thoughts: Which One’s Right for You?

Here’s the truth neither THCA nor THCP is better across the board. They’re just very different tools.

  • If you’re wellness-focused, THC-sensitive, or just want the benefits of cannabis without the high? Go with THCA.

  • If you’re chasing intensity, pain relief, or a next-level high (and you know what you’re doing)? THCP might be your new favorite.

Just don’t mix them up or underestimate them.

The Bottom Line

THCA and THCP might share a few letters, but they live on totally different planets. One’s a quiet healer. The other is a full-blown space launch.

Whichever you choose, do your research, read the labels, and know your tolerance. And as always start low, go slow, and stay safe.

FAQ’s

Is THCP stronger than delta-9 THC?
Yes, way stronger. Up to 30x more potent in lab tests.

Can you fail a drug test from THCA?
Yes. Once heated, THCA becomes THC and most tests can’t tell the difference.

Is THCA legal in my state?
Depends. Federally legal, but some states test based on “potential THC.” Check your local laws.

Can I cook with THCA flower?
You can, but the moment you add heat, it turns into THC. If you want the raw benefits, go for cold infusions or juicing.

Can beginners try THCP?
We really don’t recommend it. Start with something like delta-8 first.

Does THCP show up on a drug test?
Yep, it probably will. Even though THCP is its own cannabinoid, it’s super close to THC chemically. Most drug tests don’t look for specific cannabinoids they look for THC metabolites. So if you’ve got THCP in your system, there’s a good chance it’ll trigger a positive test just like THC would.

Does THCP need to be heated like THCA?
Nope. THCP is already active in its natural form, so you don’t need to decarb it (aka heat it up) to feel the effects. THCA, on the other hand, needs heat to convert into THC otherwise, it won’t get you high. That’s why raw THCA flower doesn’t do much until you smoke or vape it.

What’s the actual molecular difference between THCA and THCP?
Here’s the nerdy breakdown: THCA has a five-carbon tail (pentyl side chain), and THCP has a seven-carbon tail (heptyl side chain). That longer tail on THCP helps it grab onto your body’s cannabinoid receptors way more strongly like, 30 times stronger than THC. That’s a big part of why THCP hits so hard.

Can THCA and THCP be taken together?
Technically, yeah but it’s kind of like mixing chill and chaos. THCA doesn’t get you high unless you heat it, and THCP is wildly strong even in tiny doses. If you do combine them (say, using a product that has both), take it slow. You don’t want to accidentally go on a one-way rocket ride when you were just trying to unwind.

How does THCP compare to CBD or regular THC?
Totally different ballparks. CBD is non-psychoactive and doesn’t bind well to CB1 receptors (the ones responsible for feeling high). THC binds decently and gives you that classic buzz. THCP, though? It binds super tightly and can hit way harder even in small doses. So if THC is beer, THCP is like a double shot of 151.

Will THCA or THCP make me anxious?
THCA? Probably not it’s non-psychoactive, so it won’t mess with your head. THCP, on the other hand, might. Because it’s so strong, it can tip some people into anxiety territory, especially if you’re sensitive or take too much. If you’re new to strong cannabinoids, ease in with baby steps.

What kind of high does THCP give?
Think of a THC high but turned up several notches. People report deep body relaxation, intense euphoria, and sometimes trippy visuals or altered perception especially at higher doses. It’s not something to mess around with unless you’ve got a decent THC tolerance already.

How long does THCP stay in your system?
There’s not a ton of research yet, but it’s safe to assume it sticks around at least as long as THC possibly longer. That means it could linger in your fat cells and show up on a drug test for days or even weeks depending on your metabolism and usage habits.

Is THCP safe?
There’s no red flag right now, but it’s still new and understudied. It’s really potent, so the main risk is overdoing it. Start small, give it time to kick in, and don’t mix it with a bunch of other stuff the first time. If you’ve got medical conditions or take meds, ask your doctor before trying it.

What’s the best way to try THCP if I’m curious?
Low and slow. Seriously. Go for a low-dose gummy or vape from a brand that actually posts third-party lab results. Start with a microdose and give your body a chance to respond. You can always take more but you can’t un-take it.
