THCP: Effects, Risks & Legality in 2025 – The Most Powerful Cannabinoid

What is THCP and why is it causing a stir?

You've heard of THC, right? But what the heck is THCP? This thing suddenly appeared in the scientific community in 2019, and everyone's been talking about it ever since. Allegedly 33 times stronger than THC – no wonder it's being hailed as the "king of cannabinoids." But is that really true, or is it just a big marketing gimmick?

In short: THCP (tetrahydrocannabiphorol), also known as THC-P, is a naturally occurring cannabinoid in the hemp plant, but in extremely small quantities. Researchers believe it could be partly responsible for the drastically different effects of cannabis strains. But enough theory – let's look at what it can actually do.

How does THCP affect the body and the endocannabinoid system?

Weed gets you high because THC binds to the CB1 and CB2 receptors in your body. THCP does the same thing—only much, much stronger. Why? Because its alkyl chain is longer (the chemical part responsible for binding to receptors). This means:

Faster and more intense effect than regular THC
Longer-lasting high because it binds more firmly to the receptors.
Extremely psychoactive, so not for the faint of heart.

This could explain why some strains completely blow you away even though they "only" have 20% THC – perhaps there's a little bit of THCP in there too.

How strong is THCP compared to THC?

Here's where it gets interesting: According to a study, THCP is up to 33 times more active than THC . Does that mean you'll get so high with a single hit that you forget your own name? Not quite. While the potency is higher, it still depends on the dose. Here are a few facts:

THCP binds to CB1 receptors up to 33 times more strongly (CB1 is responsible for the psychoactive high).
It is up to 10 times stronger at CB2 receptors (for physical effects).
Even small amounts are enough to achieve a dramatic effect.

If you think a regular joint will knock you out – think of THCP as its big, bad sister. One hit is enough. Maybe half a hit.

Okay, but what does it feel like? According to the few available user reports, THCP has a similar effect to THC – only stronger and longer lasting. This means:

Deep relaxation, almost like body paralysis (Couchlock 3000)
Extremely euphoric high with intense colors and crazy thoughts
Longer-lasting effect – some users report a high of 12+ hours.
More severe side effects if you take too much (panic, rapid heartbeat, hallucinations)

Yes, THCP is intense. Perhaps not necessarily suitable for beginners.

How long does the effect of THCP last?

While regular THC lasts 2–6 hours, you can expect a significantly longer high with THCP. Many users report:

8–12 hours high, depending on dosage
Longer after-effects that can feel like a "weed hangover".
Enhanced "afterglow", meaning a long-lasting feeling of relaxation.

So if you want to try THCP, plan enough time and make sure you don't have an appointment in three hours.

What are the side effects and risks of THCP?

Every potent cannabinoid has its downsides. THCP is no exception. Too much of it can be unpleasant. Side effects include:

Severe paranoia and anxiety
Extremely dry mouth (Cottonmouth 5000)
Prolonged couchlock – you just can't get up anymore
Potentially stronger effects on heart rate and circulation

So: Enjoy with respect. Small doses. Start slowly. Nobody wants to experience a whitehead.

Is THCP a natural or synthetic substance?

THCP occurs naturally in cannabis – but in tiny amounts. This means:

Natural THCP is extremely rare
The THCP in vapes and extracts is mostly synthetically produced.
It is chemically converted from CBD or THC.

So if you see a THCP product, you can assume it's semi-synthetic. Is that a problem? Nope. It's simply the only way to produce larger quantities.

Is THCP legal?

Now it gets tricky. As of now (2024), THCP is in a gray area in many countries. In Germany, it is now illegal, as it falls under the NpSG (New Psychoactive Substances Act). This means:

No sale, trade or manufacture permitted
Possession is (still) not prosecuted.
Other countries, like the USA, still allow it legally in some cases.

If you want to buy it, you should find out exactly what the situation is in your country.
