Dab cannabis oil between 315°F and 450°F (157°C to 232°C). For most concentrates, the sweet spot is 350°F to 400°F, where THC and CBD turn to vapor while the terpenes stay intact. Push past 600°F and the oil scorches, the flavor turns bitter, and the vapor picks up irritants you do not want in your lungs.
Understanding Dab Temperature and Its Effects
Temperature ranges at a glance
- 315°F to 350°F: Peak flavor, thin vapor, mild effects.
- 350°F to 400°F: Balanced taste and potency. Best place to start.
- 400°F to 450°F: Thick clouds, harder hit, faster terpene loss.
- 450°F to 600°F: Heavy vapor, sharp taste, more irritating compounds.
- Above 600°F: Cannabinoid degradation and byproducts linked to lung irritation.
Why the number matters
THC boils near 315°F, and CBD falls in the same neighborhood, roughly 320°F to 356°F. Terpenes, the compounds behind the smell and much of the character of a strain, vaporize between about 310°F and 400°F. That overlap is the reason a low-temperature dab tastes like the jar smelled. Run the nail too hot and the terpenes flash off first, leaving a flat, acrid hit with a burned aftertaste that lingers in the banger.
How to dial in your temperature
- Set your e-nail, e-rig, or torch timer to 350°F.
- Load a dab about the size of a grain of rice. Larger dabs need more heat and swing the results.
- Inhale for 5 to 10 seconds with a slow, steady pull.
- Note the flavor on the first pull and how much vapor you exhale.
- Raise the temperature by 10°F to 15°F on your next session and repeat the same dab size.
- Stop stepping up when the taste turns bitter or the vapor makes you cough on contact. That is your ceiling.
- Write down the setting that worked. Concentrate type changes the answer, so live resin, rosin, and shatter often land at different numbers.
Signs your dab is too hot
- The banger glows red when you drop the oil.
- Vapor appears the instant the oil touches the surface, with a burnt, metallic taste.
- Your throat feels raw within seconds and the cough lasts minutes.
- The leftover oil turns dark brown or black instead of amber.
Signs your dab is too cool
- Little to no vapor on the first pull.
- Oil pools and stays liquid in the banger after you finish.
- Flavor is present but the effects feel weak.
Cold start compared with hot start
A cold start means you load the oil first, then heat the banger until the oil starts to bubble. This method keeps the temperature low by default and protects flavor. A hot start means heating first and letting the banger cool for a set count before you drop the oil. The count is guesswork until you pair it with an infrared thermometer or an e-rig with a digital readout. If you want repeatable results, use a device that displays actual temperature rather than estimating by glow or timing.
What you need
- Cannabis oil or another legal concentrate
- A dab rig, e-rig, or e-nail with temperature control
- An infrared thermometer if you heat with a torch
- A carb cap and a clean banger
Start at 350°F, adjust in small steps, and let flavor guide you. The right temperature is the one that gives you full taste, steady vapor, and a smooth inhale without a burned aftertaste.
