THC-C4 is a rare THC homologue also called Δ9-THCB or tetrahydrocannabutol. It has a four-carbon (butyl) side chain instead of the five-carbon (pentyl) side chain found in standard Δ9-THC.

Q: Is THC-C4 Psychoactive?

THC-C4 is considered an intoxicating THC-type cannabinoid, but the real-world experience depends heavily on purity, dose, and individual sensitivity.

Q: What Is The Vaporizing Temperature For THC-C4?

A single, universally verified boiling point for THC-C4 is not consistently published in consumer-facing references. As a practical vaporizer education guideline, most users target the same general operating range used for cannabinoids, typically around 160–220°C (320–428°F), adjusting for device behavior and material.

THC has a family. THC-C4 is one of the close cousins. Same general shape, shorter side chain, and a name that confuses people on purpose.

What THC-C4 Is

THC-C4 is a phytocannabinoid found in cannabis that is a homologue of Δ9-THC. Homologue means the same basic scaffold, but with a side chain that is one carbon shorter. Standard Δ9-THC has a C5 pentyl side chain. THC-C4 has a C4 butyl side chain.

Fast ID check: THC-C4 and Δ9-THCB are the same idea. Different labels, same C4 side chain.

How THC-C4 Compares To Δ9-THC

The “side chain length” is not trivia. It influences how cannabinoids interact with cannabinoid receptors and how they behave in real products. THC-C4 sits between the classic THC profile and the broader THC homologue lineup that includes compounds like THCV (C3) and others.

Quick Facts

Primary Names: THC-C4, Δ9-THCB, tetrahydrocannabutol
What Makes It Different: C4 butyl side chain instead of C5 pentyl side chain
Molecular Formula: C20H28O2
Molecular Weight: ~300.44 g/mol
Natural Abundance: typically rare and found in low amounts

Is THC-C4 Psychoactive?

THC-C4 is considered a THC-type cannabinoid and is generally treated as intoxicating. The intensity depends on dose, purity, and your tolerance. If someone says it is “non psychoactive,” they are either guessing or selling.

Safety note: any intoxicating cannabinoid can impair coordination and judgment. Do not drive after use. Keep products away from kids and pets.

Vaporizing Temperature For THC-C4

Honest answer: THC-C4 does not have one single, universally verified consumer boiling point that everyone agrees on. Devices also do not heat like lab glassware.

For vaporizer education, the most responsible guidance is practical: THC-C4 behaves like a THC-type cannabinoid, so most users start in the same general operating range used for cannabinoids and adjust by results. Many vaporizer designs are typically operated around 160–220°C (320–428°F), depending on airflow and heater stability.

Why People Confuse THC-C4

Multiple names: THC-C4, THCB, THC-B, tetrahydrocannabutol
Marketing blur: brands mix “new cannabinoid” hype with minimal explanation
Lab literacy gap: side-chain homologues get misread as totally different drugs

FAQ

Is THC-C4 The Same As THCB?

Yes. THCB is a common label for Δ9-tetrahydrocannabutol, also known as tetrahydrocannabinol-C4 or THC-C4.

Does THC-C4 Occur Naturally In Cannabis?

Yes, it has been reported as a phytocannabinoid found in cannabis, but it is typically described as rare and present in low amounts.

What Is The Vaporizing Temperature For THC-C4?

There is no single widely verified consumer number. For vaporizer education, treat it like a THC-type cannabinoid and use a controlled, stepped temperature session. A practical dry herb range is 365–410°F, adjusted for your device and airflow.
