Mastering the Pipe's Carb Hole: Beginner to Advanced
Quick Take: A weed pipe's carburetor (carb) is a small hole that controls airflow, dramatically affecting your smoking experience. The carb allows you to take smoother hits, adjust smoke thickness, cool down hot smoke, and maximize the effects of your prescribed strain.
Why it matters: Proper carb technique helps you inhale more comfortably, avoid wasting product, and precisely control your dosage. (learn how to inhale weed properly).
What you'll learn: How to use a carb for smoking and advanced methods for cherry activation, staggering, feathering, and cold start.
Why do weed pipes have a hole on the side?
A carburetor, or carb, is a small hole located on the side of a pipe. This simple yet crucial hole allows you to control airflow with your finger, directly impacting the power, temperature, and potency of the smoke.
The carb's primary purpose is to clear the pipe of smoke after a hit, but its abilities go far beyond that. By manipulating the carb with your finger, you can fine-tune air flow to control the smoke intake by increasing and decreasing smoke production and activating a healthy cherry for even combustion of cannabis.
Which is better: Pipe vs bong?
Why is it called a carb on a pipe?
The carb functions on principles similar to those found in automotive engines, where carburetors control the air-fuel mixture.
In a pipe, the carb controls the air-smoke mixture. When the carb is covered, airflow is restricted, allowing smoke to build up in the pipe's chamber. While inhaling and releasing your finger from the carb hole, fresh air rushes in, pushing the accumulated smoke into your lungs.
This creates a two-phase hit: the initial dense, concentrated smoke followed by a rush of cooler, fresh smoke mixed with air.
Pro-tip: The timing and technique of carb release can significantly impact your smoking experience, experiment by covering and uncovering the carb while you inhale to get a feel for how the carb uses airflow to move smoke.
How to use a carb on a weed pipe
To use a carb (carburetor) on a weed pipe, follow these steps:
- Cover the carb with your finger or thumb
- Light the bowl and begin inhaling slowly
- When the chamber fills with smoke, release the carb
- Inhale to draw fresh air through the carb, clearing the smoke
Repeat these steps until the bowl has cashed. When a bowl is “cashed”, it means that all the usable cannabis has been consumed and combusted and turns into ash.
This basic technique allows you to control the density of your hit. By covering the carb, you're restricting airflow, which concentrates the smoke in the chamber (builds up). When you release the carb, fresh air rushes in, pushing the smoke into your lungs and clearing the chamber.
How can I adjust my carb technique for different effects?
Experiment with the timing of your carb release to customize your hit:
- Quick release: For a less intense, cooler hit
- Delayed release: For a denser, more potent hit
- Partial release: Gradually uncover the carb for a controlled intake
Using the carb to activate the cherry
What is a 'cherry' and how does the carb help activate it?
A 'cherry' refers to the glowing ember of the lit herb in your bowl. Sometimes, especially with poorly grounded cannabis, the cherry can get stuck or go out prematurely. It's always important to grind and pack your pipe correctly.
The carb can help activate or rekindle the cherry through a technique called 'carb pumping'.
Carb pumping:
- Take a normal hit, but don't fully clear the chamber
- Quickly cover and uncover the carb several times
- This creates small bursts of airflow, helping to evenly distribute heat and reignite any unburned material
Why is carb pumping effective for cherry activation?
Carb pumping works by creating alternating pressure in the pipe. When you cover the carb, it forces air through the bowl, fanning the cherry. When you uncover it, it draws that heated air back through the herb, helping to spread the cherry evenly.
This technique not only helps maintain an even burn but can also help you get the most out of your herb by forcing a complete combustion cycle, which is important for extracting all the cannabinoids and terpenes from the plant.
Advanced carb techniques
- Staggered hits: Take multiple small hits without fully releasing the carb
- Carb feathering: Partially release the carb to control the smoke intake
- Cold start: Begin inhaling before lighting for a smoother initial hit
These techniques allow for finer control over your smoking experience, maximizing the effects you can get with a cannabis pipe. Below are the three advanced carb techniques broken down step by step:
1. Staggered Hits
Staggered hits let you take smaller, controlled puffs without fully releasing the carb, giving you a more gradual and prolonged session. Here’s how to do it:
- Cover the carb and light the bowl.
- Inhale gently to fill the chamber with smoke.
- Partially release the carb by lifting your finger slightly to let a bit of air in.
- Cover the carb again and repeat for small, controlled hits.
Why use staggered hits?
- Savor your cannabis: Enjoy your session at a slower pace without burning through your bowl too quickly.
- Ideal for sharing: Perfect for group sessions where you don’t want to finish the bowl in one go.
- Maintain the cherry: The intermittent airflow keeps your cannabis burning gently.
Practice the timing of lifting and covering the carb to find the rhythm that gives you the smoothest hits. This method helps you enjoy the flavors and effects without overwhelming your lungs.
2. Carb Feathering
Carb feathering lets you control the airflow for a smoother, more controlled hit. Unlike staggered hits, which focus on taking multiple small puffs, carb feathering is all aboutadjusting the airflow during a single hit.
How to feather the carb:
- Cover the carb and light the bowl.
- Inhale steadily while slowly lifting your finger to let in a little air.
- Adjust the airflow to make the smoke lighter or thicker as you like.
Why use carb feathering?
- Smooth control: Adjust the smoke intensity in one continuous hit, making it easier to get just the right amount.
- Gentle transitions: This method helps you avoid harsh hits by giving you control over how the smoke builds up.
- Keep the cherry going: Feathering ensures a steady burn by letting in just enough air to keep the cannabis lit without burning too quickly.
Carb feathering is great for those who like to take one long, steady pull and adjust the smoke’s thickness as they go. It’s all aboutfinding that sweet spot for a more enjoyable hit, making it different from the repetitive rhythm of staggered hits.
3. Cold start carb
The cold start technique is all about starting your inhale before lighting the bowl, priming the airflow for a smoother, gentler first hit. Here’s how to do it:
How to cold start:
- Cover the carb and start inhaling through the mouthpiece.
- Bring the flame close to the cannabis, but don’t touch it directly.
- Keep inhaling as the heat gradually lights the cannabis.
- Once the cherry is lit, remove the flame and continue to inhale, releasing the carb to clear the chamber when ready.
Why use cold start carb?
- Smoother hits: Starting cold allows the smoke to build gradually, reducing the harshness of the first hit.
- Better flavor: The slower ignition helps preserve the cannabis's flavor by avoiding scorching.
- Gentle on the lungs: Ideal for those who want a less intense start to their session or are sensitive to strong initial hits.
This technique takes a bit of practice to coordinate your inhale with lighting, but once you get the hang of it, it can make your sessions much easier on the throat and lungs. Perfect if you struggle with coughing and need a gentler hit from a cannabis pipe.
Where is the carb located on my pipe?
Carbs are typically found on the side of the pipe near the bowl. On most standard hand pipes, you'll see a small circular hole on the left side of the bowl. This is your carb. Some pipes may have the carb positioned differently, such as the front of the pipe (steamrollers), but side placement is most common.
The carb’s location can change depending on the type of pipe you have. Some pipes like chillums, one-hitters, and glass blunts do not have carb holes, but you can place your finger over the bowl to control airflow. Hand pipes are generally the only smoking devices that have carbs besides a few bongs.

Why does carb placement matter?
The location of the carb can affect your smoking experience in important ways:
- Side carbs (most common): Offer a balanced experience and are easy to use
- Front carbs (steamrollers): Provides the most airflow for stronger hits
- Back carbs: Often result in denser hits but can be harsher
How can I use the carb to control smoke temperature?
The carb plays a crucial role in managing smoke temperature. By releasing the carb earlier in your hit, you allow cooler air to mix with the smoke, helping to cool hot smoke for a gentler inhale. On the other hand, keeping the carb closed for longer will result in denser, warmer smoke which can lead to coughing but is more potent.
If you find the smoke too harsh, try carb pumping as described earlier. This introduces small bursts of fresh air, cooling the smoke without significantly diluting it.
Did you know? A glycerin pipe introduces frozen glycerin which helps cool hot smoke by 300 degrees to prevent coughing.
How do I pack my pipe for optimal carb use?
Packing your weed pipe right makes a big difference when using the carb. Grind your cannabis to a medium consistency - small pieces, but not powdery. This allows air to flow evenly through the herb. Fill the bowl gently, leaving some space for airflow.
Don't compress the cannabis; a loose pack ensures proper combustion and makes it easier to draw smoke through the pipe. Good airflow is crucial for getting the most out of your carb hole and enjoying your smoke.
Maintaining your carb for optimal performance
Keeping your carb clean helps it work better. After smoking, wipe the carb hole with a pipe cleaner or cotton swab. For a thorough clean follow the same steps as you would when cleaning a pipe:
- Soak your pipe in rubbing alcohol for half an hour
- Gently scrub the carb hole with a pipe cleaner
- Rinse well with warm water
- Let it dry completely before using again
A clean carb means smoother hits and less gunk buildup. It's worth the effort to keep your pipe in good shape.
When should I clean the carb hole?
- Difficulty drawing smoke through the pipe
- Uneven or unpredictable airflow when using the carb
- Visible residue or blockage in the carb hole
- Strange tastes or odors when smoking
Final thoughts
Mastering your pipe's carb can drastically improve your experience when smoking. This small hole controls airflow, letting you fine-tune each hit. Start by covering the carb as you light and inhale, then release it to clear the chamber.
As you get comfortable, try advanced techniques like feathering for smoother hits or cold starts for gentler sessions.
A well-packed bowl is key - grind your cannabis to a medium consistency and don't overfill. With practice, you'll learn to manage smoke density and temperature, getting the most out of your strain. Experiment and find what works best for you!
