Every compound in cannabis has a boiling point — a specific temperature at which it transitions from solid or liquid to vapor. Set your vaporizer too low and you get wispy clouds of mostly terpenes with minimal THC. Set it too high and you are combusting plant material, defeating the entire purpose of vaporizing.
The gap between these extremes is where the art of vaporizing lives, and most people never leave the factory default setting on their device.
Understanding what vaporizes at each temperature gives you control over your experience in a way that no other consumption method offers. You can target specific compounds, modulate your high in real time, and extract everything useful from your flower in a single session using a technique called step-temping.
The Boiling Points You Need to Know
Cannabis contains over 100 identified cannabinoids and more than 200 terpenes, but a handful dominate the experience. Here are the key compounds and when they become vapor.
Terpenes (Low Temperature: 310–350°F / 155–177°C)
Terpenes are the most volatile compounds in cannabis, which is why they are the first to vaporize and the first to degrade.
Pinene boils at around 311°F (155°C). This is the fresh, piney terpene associated with alertness and bronchodilation. If you want maximum pinene, start your session at the lowest effective temperature.
Myrcene boils at approximately 334°F (168°C). The most abundant terpene in cannabis, myrcene is associated with sedation and the “couch lock” effect in indica-dominant strains. It has an earthy, musky aroma.
Limonene vaporizes around 349°F (176°C). Citrusy and energizing, limonene is linked to mood elevation and stress relief in preclinical studies.
At these low temperatures, you will taste the full terpene profile of your flower but get relatively little cannabinoid vapor. This is ideal for “flavor chasers” who want to appreciate a strain’s aromatic complexity before ramping up the heat.
THC and Primary Cannabinoids (Medium: 350–390°F / 177–199°C)
THC boils at approximately 315°F (157°C) but vaporizes most efficiently between 350–380°F. This is the sweet spot for most recreational users — you get robust THC vapor, remaining terpenes, and smooth hits without harshness.
CBD has a higher boiling point at around 356°F (180°C) and vaporizes best between 365–390°F. If you are using a high-CBD strain or a 1:1 THC:CBD strain and want to actually get the CBD, you need to be above 360°F.
CBN (the sleepy cannabinoid formed when THC oxidizes) boils around 365°F (185°C). Older flower with partially degraded THC will produce more CBN vapor at this temperature.
CBC (cannabichromene) vaporizes around 428°F (220°C), so it requires higher temperatures to access.
Deep Extraction (High: 390–430°F / 199–221°C)
Caryophyllene — the peppery terpene that binds to CB2 receptors — boils around 390°F (199°C). This is one of the last terpenes to vaporize and contributes to the heavier, more body-focused effects felt at higher temperatures.
Linalool (the lavender terpene) also vaporizes in this range at approximately 388°F (198°C), adding sedative and anxiolytic effects.
THCV boils at around 428°F (220°C), which is why this rare cannabinoid is often missed entirely by users vaping at standard temperatures.
Humulene vaporizes at approximately 388°F (198°C) and is associated with appetite suppression — the opposite of the classic munchies effect.
Above 430°F, you are approaching combustion territory. While true combustion does not occur until around 450–460°F, the vapor becomes harsh, the flavor degrades significantly, and you start inhaling more pyrolytic byproducts.
Step-Temping: The Professional Technique
Step-temping (also called temperature stepping) is the method used by serious vaporizer enthusiasts to extract every compound from a single bowl. The technique is simple:
-
Start at 340–350°F. Take 3–5 draws. You will get maximum terpene flavor with a mild, clear-headed effect. The vapor will be thin and flavorful.
-
Step to 370°F. Take 3–5 more draws. This is where THC and CBD vapor production peaks. The clouds get thicker, the effects get stronger, and you still retain some terpene character.
-
Step to 390°F. Another 3–5 draws. The flavor shifts from sweet/fruity to toasty/earthy. You are extracting the heavier terpenes and remaining cannabinoids. Effects become more body-dominant.
-
Finish at 410–420°F. The final draws extract any remaining active compounds. Flavor is minimal — mostly toasty — but you are getting every last bit of value from the flower.
After a full step-temp session, your ABV (already-been-vaped) flower should be dark brown and evenly colored. If it is still greenish, you left compounds on the table. If it is black, you went too high and combusted.
Temperature Settings for Specific Situations
Morning/productivity session: 340–365°F. Lower temperatures produce a cerebral, energizing effect with minimal sedation. You get THC and the uplifting terpenes (pinene, limonene) without the heavier body effects.
Social/creative: 365–380°F. The middle range produces a balanced high — present but functional. You get good THC extraction with enough terpenes to keep the experience nuanced.
Pain management: 380–400°F. Higher temperatures extract CBD, CBN, and the anti-inflammatory terpenes (caryophyllene, humulene). The effect is more body-focused and sedating.
Sleep/deep relaxation: 390–420°F. Maximum extraction of sedating compounds — myrcene, linalool, CBN. The trade-off is harsher vapor and less flavor, but the heavy body effect is what you want before bed.
Flavor appreciation: 320–350°F. Pure terpene tasting. Minimal psychoactive effect, maximum aromatic complexity. Useful when trying a new strain for the first time and wanting to understand its terpene profile before getting high.
Device Accuracy Matters More Than You Think
Not all vaporizers are created equal when it comes to temperature accuracy. A vaporizer that displays 370°F might actually be heating your herb to 350°F or 390°F depending on the quality of the temperature sensor, the heater type, and the chamber design.
Convection vaporizers (hot air passes through the herb) tend to produce more consistent temperatures across the chamber. The herb heats evenly and you get more predictable extraction at each temperature step.
Conduction vaporizers (herb sits on a heated surface) create temperature gradients — the herb touching the heater wall might be at 400°F while the center of the chamber is at 340°F. Stirring the chamber between draws helps, but the extraction is inherently less precise.
Hybrid vaporizers use both methods and generally offer the best combination of efficiency and flavor. Most premium portables released in 2025–2026 use hybrid heating.
If temperature precision matters to you, look for devices that use PID temperature controllers (proportional-integral-derivative) rather than simple on/off heating elements. PID controllers continuously adjust power to maintain target temperature within a few degrees.
ABV: Do Not Throw It Away
Already-been-vaped flower still contains cannabinoids — typically 10–30% of the original content depending on your vaporization temperature. Lower temperature sessions leave more behind.
ABV can be used for edibles (it is already decarboxylated from the heat), tinctures, capsules, or infused into butter and oil. The flavor is toasty rather than floral, but the potency is real. Many users save their ABV in a jar and make edibles once they have accumulated enough — effectively getting two uses from every purchase.
The Science of Why Temperature Matters
When you combust cannabis (smoking), every compound vaporizes simultaneously at 450°F+ along with the plant cellulose, lignin, and other organic material. You get all the cannabinoids and terpenes, but also carbon monoxide, tar, and carcinogenic compounds.
Vaporizing below combustion temperature eliminates most of these harmful byproducts while still delivering the active compounds. But because each compound has a different boiling point, your temperature setting determines which compounds you receive and which you leave behind.
This is why “what temperature should I vape at?” does not have a single correct answer. It depends on what you want from the session — and now you know exactly how to dial it in.
