The short answer
A cannabis vape temperature chart in Celsius runs from about 120°C to 230°C. Terpenes release first, THC and CBD follow in the mid-150s through the 180s, and the heaviest effects show up between 185°C and 220°C. Above 230°C you are at the edge of combustion, not vaporization, and the vapor turns harsh.
- 120 to 150°C (248 to 302°F): Terpenes only. Thin, fragrant vapor with almost no cannabinoids.
- 155 to 165°C (311 to 329°F): THC starts vaporizing. Light, functional, clear-headed effects.
- 165 to 185°C (329 to 365°F): The balanced zone. THC, CBD, and most terpenes are all active.
- 185 to 200°C (365 to 392°F): More body load and sedation. Flavor fades as the light terpenes run out.
- 200 to 220°C (392 to 428°F): Thick, potent vapor that is harder on the throat.
- 230°C and up (446°F+): The edge of vaporization. Trace irritants appear in lab testing and flavor is gone.
Those numbers are approximate. Moisture content, grind, oven design, and how hard you pull can shift the real temperature at the material by 10°C or more.

Why the same flower feels different at 165°C and 210°C
Cannabinoids and terpenes do not all boil at once. Each compound has its own vaporization point, so raising the heat unlocks a new set of them. THC is usually listed near 157°C and CBD in the 160 to 180°C range. Terpenes are lighter still: beta-caryophyllene near 119°C, alpha-pinene around 155°C, myrcene near 167°C, limonene near 176°C, and linalool closer to 198°C.

That is why the first draws at a low setting taste like the strain and the final draws at a high setting taste like toasted plant matter. The flavor compounds left the oven a long time ago.

Where most people land
180 to 190°C is the setting I see recommended most often, and the logic holds up. THC and CBD are both fully in play, most terpenes have vaporized, and the vapor is still cool enough to be comfortable. Want flavor? Drop to 165°C. Want the sedating end of the spectrum? Step up to 200°C or a little beyond.
Cartridges do not follow the same chart
Oil carts work differently. The coil inside a 510 cartridge can spike well above 300°C for a fraction of a second, and the oil around it never reaches a steady temperature the way flower in an oven does. You are not setting a temperature. You are setting voltage or wattage, and the real heat depends on coil resistance, oil viscosity, and how long you hold the button.
A rough translation: 2.0 to 2.5 volts runs cool and protects terpenes, 3.0 to 3.5 volts is the middle, and 4.0 volts and up burns through oil fast and tastes scorched by the end of the cart. Live resin and rosin carts usually want the low end. Distillate with added terpenes can handle a little more.
Celsius to Fahrenheit without doing the math
- 150°C = 302°F
- 160°C = 320°F
- 170°C = 338°F
- 180°C = 356°F
- 190°C = 374°F
- 200°C = 392°F
- 210°C = 410°F
- 220°C = 428°F
For anything off the list, the formula is Fahrenheit = Celsius x 1.8 + 32. Most dry herb devices sold in the US ship set to Fahrenheit, so it helps to know that 180°C is 356°F and 200°C is 392°F.
How to find your own number
- Start at 165°C and take two or three slow draws.
- Step up 10°C and repeat. Note how flavor and body feel change.
- Stop when the vapor gets harsh or tastes like burnt popcorn. That is your ceiling.
- Stir the chamber between steps so the material heats evenly.
What shifts the number in real life
- Moisture: Dry flower vaporizes faster. Fresh flower needs more heat.
- Grind: A fine, even grind exposes more surface area and heats faster.
- Oven type: Convection devices run cooler at the material than conduction ovens set to the same number.
- Draw speed: Long, hard pulls move heat away and can leave the load undercooked.
On the legal market side
Regulated flower and cartridges come with lab results, and the terpene panel is the part worth reading before you pick a temperature. A strain heavy in limonene and pinene rewards a low first draw; a myrcene-dominant one tends to shine in the 185 to 200°C range. Lab-tested products also tell you what you are inhaling, which matters because the lung injuries reported in 2019 were tied to vitamin E acetate in unregulated cartridges, not to temperature settings on tested goods.
One last habit worth building: change one variable at a time. Same strain, same grind, same draw length, one temperature step. After a few sessions you will have a personal chart that beats any generic one.
