Dabbing is vaporizing a small amount of cannabis concentrate on a surface heated to roughly 450–600 °F and inhaling the vapor through a water-filtered rig. The three ways to do it are a torch-heated quartz banger, a battery-powered e-rig, or a handheld nectar collector.
A first dab should be half a grain of rice. Concentrates run 60–90% THC, so one normal dab is 3–10 times the dose of a puff of flower. If you want the easiest, safest start, an e-rig at 500 °F removes the torch, the timing and most of the ways quartz gets cracked.
What Is a Dab, and How Strong Is It?
A dab is a single small serving of cannabis concentrate, about the size of a grain of rice, vaporized on a hot surface. Because concentrates test at 60–90% THC, that grain carries roughly 25–50 mg of THC — the equivalent of several puffs of flower in one breath.
A concentrate is what you get when the resin glands (trichomes) are separated from the plant, by solvent (butane, propane, CO2, ethanol) or by heat and pressure alone. The texture on the label tells you how it was finished, not how strong it is; potency comes from the lab result.
| Form | Texture | How it’s made | Typical THC | Flavor |
|---|---|---|---|---|
| Shatter | Glassy, brittle sheet | Hydrocarbon extraction, purged flat | 70–85% | Moderate; terpenes partly lost in the purge |
| Badder / budder | Whipped, cake-frosting | Hydrocarbon extraction, agitated as it purges | 65–85% | Good |
| Live resin | Saucy to badder | Hydrocarbon extraction from flash-frozen fresh plant | 65–85% | High; the freshest terpene profile |
| Cured resin | Varies | Hydrocarbon extraction from dried, cured flower | 65–85% | Moderate |
| Live rosin | Badder to jam | Ice-water hash pressed with heat; no solvent | 65–80% | High; the connoisseur pick |
| Diamonds & sauce | THCA crystals in terpene liquid | Hydrocarbon extraction, slow crystallization | 80–95% (diamonds alone 95%+) | High if the sauce is included |
| Distillate | Clear, thick oil | Molecular distillation; terpenes stripped | 85–95% | None unless terpenes are added back |
Do the dose math before your first dab. 0.05 g (a normal grain-of-rice dab) × 80% THC = 40 mg of THC in one inhalation. One puff of 20% flower is roughly 3–5 mg. That is why a first dab should be half that size, and why people who dab are twice as likely to report having taken too much than people who smoke flower (Loflin & Earleywine 2014).

Torch and Quartz vs. E-Rig vs. Nectar Collector: Which Should You Use?
A torch and quartz banger gives the best flavor for the least money but you control the temperature by timing. An e-rig sets an exact temperature at the press of a button and is the easiest to learn. A nectar collector is the portable, low-cost option for dabbing straight from the jar.
| Torch + quartz banger | Electronic rig (e-rig) | Nectar collector | |
|---|---|---|---|
| How it heats | Butane torch, 20–45 s | Battery + ceramic or quartz cup, set temperature | Torch on a quartz tip, or battery on an electric tip |
| Temperature control | Timing, or an IR thermometer | Exact, ±10 °F | Timing (torch) or presets (electric) |
| Cost | $60–200 rig, $20–60 banger, $20–40 torch, $10–30 cap | $150–400 | $30–80 torch model; $80–200 electric |
| Flavor | Best (fresh quartz, cool dab) | Very good | Good; less water filtration |
| Learning curve | Highest | Lowest | Low |
| Portability | Low | Medium | High |
| Maintenance | Swab every dab; replace banger every few months | Swab atomizer; replace atomizer ($30–80) every 6–12 months | Swab or soak tip |
| Best for | Flavor chasers, home use | Beginners, consistency, sharing | Travel, quick small dabs |
If you dab a few times a month and want flavor for the least money, torch and quartz. If you are new, share your rig, or simply want it to work the same every time, an e-rig pays for itself in wasted concentrate you do not burn. Ask a budtender; we carry both.
How Hot Should a Dab Be?
450–550 °F is the sweet spot for a low-temperature dab: full vaporization with the terpenes intact. Below about 450 °F the oil may puddle; above about 650 °F it tastes harsh and most terpenes are gone; above roughly 700 °F the oil can combust and produce new toxicants.
| Range | Name | What you get | Trade-off |
|---|---|---|---|
| 400–450 °F | Cold start / very low | Maximum flavor, small soft vapor | May leave an unvaporized puddle; needs a good cap |
| 450–550 °F | Low-temp | Full flavor, full dose, smooth | The recommended range |
| 550–650 °F | Medium | Bigger, denser vapor; faster | Noticeably less flavor; harsher |
| 650 °F + | High-temp | Instant, huge cloud | Burnt taste, terpenes destroyed, throat irritation; combustion and toxicant formation above ~700 °F |
The reason flavor disappears as you go hotter is that terpenes boil off at different temperatures, and all of them are gone well before 650 °F: β-caryophyllene at about 266 °F, α-pinene about 311 °F, myrcene about 332 °F, limonene about 349 °F, linalool about 388 °F (Russo 2011). Above roughly 700 °F, terpenes themselves start to break down into irritants like methacrolein and benzene (Meehan-Atrash 2017), which is the real argument for staying low.
A $20 infrared thermometer is the single best accessory for a torch user. Point it at the bottom of the banger; when it reads 500–550 °F, go. It removes every argument about counting seconds.
How to Take a Low-Temp Dab with a Torch (Step by Step)
Fill, load, heat 20–45 seconds, cool 30–60 seconds, drop and swirl, cap, then swab while warm. The two steps beginners skip are the cool-down and the swab, and they cause most burnt dabs and ruined bangers.
Terp pearls (small quartz or ruby balls dropped into the banger) spin under a directional cap and spread the oil across the hot surface. They let you run cooler with no puddle. Optional, but the best $10 upgrade after a thermometer.
How to Use an E-Rig
Charge it, fill the glass to the line, set the temperature (start at 500 °F), load the dab into the cold cup, press to start, cap, and inhale when the light or vibration tells you it is ready. Cleaning is a swab of the cup after each session.
Every e-rig differs in detail, so the manual wins where this differs. The common pattern: the device heats for 20–40 seconds, holds the temperature for a session window of 15–60 seconds, and then cools. Load before heating, not after; the cup is not designed for a hot drop. Most devices offer presets in the 450–600 °F range; work down from 500 °F until the dab leaves a small puddle, then step back up 25 °F. Never submerge the base, and let the atomizer cool completely before you swab it with isopropyl.
How to Use a Nectar Collector
Heat the tip for 15–30 seconds, let it cool 10–20 seconds, then touch the tip to a small amount of concentrate in a glass or silicone dish while inhaling through the mouthpiece. Never dip into the full jar; the tip stays hot for minutes.
The nectar collector is a straw: a quartz or titanium tip, sometimes a small water chamber, and a mouthpiece. Its strength is dose control by contact time: touch briefly for a small dab, longer for more. Its weakness is that the hot tip is exposed, so it needs a stable place to rest and a dish that will not melt. Electric versions replace the torch with a battery-heated tip at fixed presets and remove most of the risk.
Cold-Start (Reverse) Dabbing
Load the dab into a cold banger, cap it, then heat gently for 5–10 seconds until the oil bubbles and vaporizes. The temperature never gets high, the flavor is excellent, and the banger stays cleaner longer.
Cold start is the low-effort way to a low-temp dab: no cool-down count, no thermometer, and less reclaim because nothing is overheated. The trade-offs are a smaller vapor volume per hit and the need to swab immediately, because the puddle left behind will scorch on the next heat-up. It also works only with quartz; e-rigs already load cold by design.
How Do You Prevent Thermal Shock and Cracked Quartz?
Quartz cracks when its temperature changes suddenly, not when it gets hot. Heat it evenly and slowly, never put water or a wet swab on a hot banger, never torch a banger with liquid in it, and let it cool fully before an isopropyl soak.
- Heat the bottom and lower walls, not the joint. The joint is where the banger meets the rig; concentrated heat there is the classic crack.
- Keep the flame moving. A torch held still on one spot creates a hot spot; a slow circle spreads the heat.
- No water on hot quartz. This includes splash-back from an overfilled rig and the wet iso swab. Dry swab first, then iso once the glow is gone.
- Never torch reclaim or leftover puddle. Liquid in the bucket boils and stresses the glass. Swab it out first.
- Cool before soaking. A warm banger into room-temperature iso is fine; a hot one is not.
- Store dry and separate. Water left in a rig with the banger attached leads to a banger torched wet.
| Material | Flavor | Heat-up | Heat retention | Durability | Notes |
|---|---|---|---|---|---|
| Quartz | Best | Fast | Low (cools quickly) | Moderate; cracks from shock, chazzes from overheating | The standard. Thicker bottoms hold heat longer |
| Titanium | Metallic until seasoned | Fast | High | Very high | Needs seasoning; can leach if low grade; buy Grade 2 |
| Ceramic | Very good | Slow | High | Low; cracks easily | Common in e-rig cups where heating is controlled |
How Do You Clean a Banger and Rig?
Swab after every dab while the quartz is warm, soak the banger in 99% isopropyl weekly, and clean the rig monthly with isopropyl and coarse salt. A banger that has turned cloudy white is chazzed and needs replacing, not cleaning.
Reclaim is the amber residue that collects inside the rig. It is mostly decarboxylated THC with the terpenes gone; you can rinse it out with iso into a dish, let the alcohol evaporate completely (a day in a ventilated room, never heat), and use it in edibles. It is not worth re-dabbing.
Safety
The two real hazards are the torch and the dose. Use butane in a ventilated room away from anything flammable, put the rig on a stable surface, sit down for your first dabs, and keep water nearby.
- Half a grain of rice. You can take a second one in 15 minutes.
- Sit down. A first dab can cause a coughing fit, a head rush and sweating; standing up is how people fall.
- Torch: refill outdoors, never near a flame, and let it cool before storing. Keep it away from the edge of the table.
- The banger, tip or cup stays dangerously hot for minutes after it stops glowing. Treat it like a stove element.
- Never dab and drive. Concentrate impairment is stronger and lasts as long as flower.
- If you take too much, you are not in danger: dim room, water, snack, slow breathing, rest. Poison Control 1-800-222-1222 is free and confidential.
