Cannabinoids Explained: THC, CBD, CBN, CBG & More

Cannabinoids are the active chemical compounds in cannabis responsible for everything you feel when you vaporize, from the psychoactive high of THC to the calming body effects of CBD. Scientists have identified over 100 distinct cannabinoids in the cannabis plant, each with its own boiling point, receptor affinity, and therapeutic profile.

For vaporizer users, cannabinoids matter because temperature determines which compounds you actually inhale. Set your vape to 170°C and you'll get a THC-forward, clear-headed experience. Push to 210°C and heavier compounds like CBN enter the mix, shifting effects toward sedation. Understanding these compounds gives you direct control over your sessions.

Cannabis produces over 100 unique cannabinoids

Cannabinoids are a class of chemical compounds produced in the trichomes of the cannabis plant. These resinous glands coat the flowers and leaves, concentrating the compounds that give each strain its unique effects and flavor.

The cannabis plant doesn't produce cannabinoids in their active form. Instead, it synthesizes cannabinoid acids like THCA and CBDA. These acids convert to their active counterparts (THC, CBD) through a process called decarboxylation, which requires heat.

This is where vaporizers come in. When you heat cannabis to a specific temperature, you trigger decarboxylation without combustion. A vaporizer operating at 185°C activates THC-A into THC while preserving terpenes — which begin vaporizing as low as 150°C — that would be destroyed by the 600°C+ temperatures of a lighter flame. Our temperature guide covers these thresholds in detail.

THC and CBD are the two most researched cannabinoids

Delta-9-tetrahydrocannabinol (THC) is the primary psychoactive compound in cannabis. It binds directly to CB1 receptors in the brain, producing the euphoria, altered perception, and appetite stimulation associated with cannabis use. THC has a boiling point of approximately 157°C, making it one of the first cannabinoids released during vaporization.

Cannabidiol (CBD) does not produce intoxication. It interacts with the endocannabinoid system indirectly, modulating CB1 and CB2 receptors without binding strongly to either. Research published in peer-reviewed journals links CBD to anti-inflammatory, anxiolytic, and anticonvulsant properties.

The ratio of THC to CBD in your cannabis matters as much as the strain name. A 1:1 THC:CBD strain vaporized at 185°C produces noticeably different effects than a 20:1 THC-dominant strain at the same temperature. If you're exploring CBD-forward strains for therapeutic use, our guide to vaporizers for medical cannabis covers the best options.

CBD doesn't cancel THC, but it modulates how THC binds to CB1 receptors. Strains with a 1:1 or 2:1 THC:CBD ratio tend to feel more manageable than high-THC strains with minimal CBD, which is part of why people gravitate toward balanced ratios for daily use.

6 minor cannabinoids that shape your experience

Beyond THC and CBD, several minor cannabinoids influence how cannabis feels and functions. Each has a distinct boiling point and effect profile.

CBN (Cannabinol) — boiling point: ~185°C

CBN forms when THC degrades through exposure to heat, light, or oxygen. It's mildly psychoactive and associated with sedation. Older cannabis tends to have higher CBN content, which is why aged flower often produces sleepier effects. Vaporizing at 185°C and above begins to release CBN into your vapor.

CBG (Cannabigerol) — boiling point: ~52°C (decarboxylation onset)

CBG is the chemical precursor to both THC and CBD. Young cannabis plants contain high levels of CBGA, which enzymes convert into THCA, CBDA, or CBCA as the plant matures. CBG-dominant strains are increasingly cultivated for their potential anti-inflammatory and antibacterial properties.

CBC (Cannabichromene) — boiling point: ~220°C

CBC is the third most abundant cannabinoid in some strains. It doesn't bind effectively to CB1 receptors, so it produces no high on its own. Research suggests it may contribute to pain relief and work synergistically with other cannabinoids.

THCV (Tetrahydrocannabivarin) — boiling point: ~220°C

THCV is structurally similar to THC but behaves differently. At low doses, it may actually block CB1 receptors, potentially reducing the intensity of a THC high. At higher doses, it becomes mildly psychoactive. THCV is most common in African sativa genetics.

Delta-8-THC — boiling point: ~175°C

Delta-8-THC occurs naturally in trace amounts. It binds to the same CB1 receptors as Delta-9-THC but with lower affinity, producing a milder psychoactive effect. Most commercial Delta-8 products are synthetically converted from CBD.

CBDV (Cannabidivarin)

CBDV is a CBD analog found in indica-dominant landrace strains. Early research focuses on its potential anticonvulsant properties, similar to CBD but with a slightly different pharmacological profile.

Your body has a built-in cannabinoid system

The endocannabinoid system (ECS) is a biological signaling network present in all mammals. It consists of three components: endocannabinoids your body produces naturally, the receptors they bind to, and the enzymes that break them down.

CB1 receptors concentrate in the brain

CB1 receptors are found primarily in the central nervous system. They regulate mood, memory, pain perception, and appetite. THC's psychoactive effects come almost entirely from its interaction with CB1 receptors. When you vaporize THC-rich cannabis, these receptors are the target.

CB2 receptors are found throughout the immune system

CB2 receptors are distributed in immune cells, the spleen, and the gastrointestinal system. CBD and CBG interact with CB2 receptors more prominently, which is why these cannabinoids are associated with anti-inflammatory effects rather than intoxication.

Your body produces its own cannabinoids (called endocannabinoids) including anandamide and 2-AG. These molecules regulate baseline functions like sleep, appetite, and immune response. Plant-derived cannabinoids from cannabis interact with the same receptor network, which is why the effects are so wide-ranging.

Your body has a receptor network built specifically for cannabinoids. Cannabis works on you because the evolutionary infrastructure was already there.

Each cannabinoid has a specific boiling point

Temperature is the single most important variable for controlling which cannabinoids enter your vapor. The table below shows approximate boiling points for the most relevant compounds.

These temperatures represent the point at which each compound begins to vaporize. In practice, efficient extraction requires sustaining a temperature slightly above the boiling point for the compound you're targeting.

This is why vaporizers with 1°C precision matter. The Volcano Hybrid holds its set temperature within 1°C across an entire balloon fill, extracting cannabinoids consistently from the first draw to the last. Portable vapes with less precise heaters can fluctuate by 10-15°C, leading to inconsistent cannabinoid profiles hit to hit.

The entourage effect depends on full-spectrum extraction

The entourage effect is the theory that cannabinoids, terpenes, and flavonoids work together to produce effects greater than any single compound alone. A 2011 review by Dr. Ethan Russo in the British Journal of Pharmacology documented multiple synergistic interactions between cannabinoids and terpenes.

For example, the terpene myrcene may increase cell membrane permeability, potentially allowing THC to cross the blood-brain barrier more efficiently. Linalool combined with CBD may enhance anti-anxiety effects. These interactions depend on preserving the full spectrum of compounds during extraction.

Vaporizers are better tools for the entourage effect than smoking because they operate within the temperature window where cannabinoids and terpenes coexist. Combustion (above 230°C) destroys many terpenes before they reach your lungs. A session starting at 175°C and stepping up to 210°C captures the widest range of compounds.

Vaporizers extract cannabinoids more efficiently than smoking

A 2004 study published in the Journal of Cannabis Therapeutics found that vaporizers converted approximately 46% of available THC into vapor, compared to 25% for combustion in a joint. More recent research using the Volcano (a convection desktop) showed conversion rates above 50% under controlled conditions.

Combustion produces over 100 known toxins including benzene, toluene, and naphthalene. These byproducts form when plant material burns above 230°C. Vaporizers operating between 170°C and 210°C stay well below that threshold, delivering cannabinoids without the carcinogenic compounds found in smoke. Our health and safety overview covers the research in depth.

Efficiency also depends on your vaporizer's heating method. Hybrid heating (combining conduction and convection) tends to extract cannabinoids more thoroughly because it heats cannabis from multiple directions simultaneously. The Mighty+ uses this approach, which is one reason its extraction consistency ranks so high in our testing. Pure convection vapes like the Tinymight 2 can match or exceed hybrid extraction on a per-hit basis, but require more technique.

Practical temperature ranges for targeting cannabinoids

VapeExperts recommends a three-stage temperature approach to capture the full cannabinoid and terpene spectrum from a single load.

170-180°C: Flavor and THC forward

This range activates THC and most terpenes while leaving heavier cannabinoids untouched. Expect light, flavorful vapor with a clear-headed, cerebral effect. Best for daytime use and microdosing.

185-195°C: Balanced extraction

The sweet spot for most users. CBN, CBD, and additional terpenes join the profile, creating fuller effects with a balance of mental and physical sensations. Most session vaporizers perform best in this range.

200-210°C: Maximum extraction

All major cannabinoids are active. Vapor becomes denser and effects shift toward sedation and body relaxation. This is where CBC and THCV begin to release. Staying below 220°C keeps you safely under the combustion threshold.

On-demand vaporizers like the Venty offer a unique advantage for cannabinoid targeting. Its 20-second heat-up and adjustable airflow let you start low, take a few terpy draws, then bump temperature to finish extraction in the same load. This progressive approach captures compounds across the full boiling point spectrum without committing to a single temperature. Our heating methods guide explains how different heater types affect extraction behavior.
