The Short Answer
To smoke a bong you need five things: the bong itself, water, ground cannabis, a lighter, and a stable surface to set it on. A screen, a grinder, and a poker help but are not required. A clean piece matters more than any accessory, because resin buildup kills flavor and cuts airflow.
what do you need to smoke a bong
- Bong with a bowl and a downstem, or a fixed percolator
- Water, enough to cover the bottom of the downstem
- Ground cannabis, about 0.1 to 0.3 grams per bowl for most people
- Lighter, or a hemp wick if you want to skip butane taste
- A table or flat surface so you do not lose water or tip the piece
That is the whole list. The rest of this guide covers the details, the optional upgrades, and the mistakes that waste flower.

What You Need: The Core Gear
A bong that fits your hand
Bongs come in sizes from 8 inches to over 18 inches. Small pieces hit hot and harsh, while larger pieces hold more smoke and cool it. Pick a beaker or straight tube for a first bong.
How to Pack a Bong Bowl: Step-by-Step Guide for Smooth Hits
Glass beats plastic. Plastic tubes scratch and hold smell. Glass costs more at the start and lasts years if you clean it.
Check the joint size too. A 14mm joint takes a wider range of bowls and ash catchers than a 10mm joint.
Water
Tap water works. Cold water and ice make the hit smoother, though ice causes more condensation and more cleaning. Fill to just above the bottom of the downstem.
Ground cannabis
A bong bowl needs ground flower, not whole nugs. Whole nugs burn uneven and clog airflow. A medium grind pulls heat through the bowl at an even rate and gives you a full hit.
Resin-heavy or sticky flower gums up a bowl fast. If your bud feels wet, leave it out for ten minutes before you grind.
A lighter or hemp wick
A standard lighter is fine. Corner the bowl and pull the flame to the edge of the herb rather than torching the middle. Hemp wick burns cooler and adds no butane taste.
Optional Gear That Helps
- Screen: keeps ash and small bits out of the water. Brass or stainless steel, sized to your bowl.
- Ash catcher: traps ash before it reaches the main chamber. Keeps the water clear longer.
- Poker or dab tool: loosens a clogged bowl without digging at it with a key.
- Grinder: even particle size, less mess on the table.
- Airtight jar: keeps flower from drying out between sessions.
- Rolling tray or mat: catches crumbs and protects the table.
- Cleaning kit: isopropyl alcohol, coarse salt, and pipe cleaners.
How to Set Up and Smoke a Bong
- Fill the bong with water until the downstem sits about half an inch underwater.
- Grind your flower to a medium consistency.
- Load the bowl with a light pack. Do not press it down tight.
- Hold the bong with one hand and the bowl with the other.
- Spark the herb at the edge while you inhale. Pull slow and steady.
- Clear the chamber by lifting the bowl or pulling the carb.
- Inhale the smoke, then exhale.
- Empty the bowl and dump the water after the session.
How Much Water Goes in a Bong?
Pour in enough water to cover the bottom of the downstem by about 0.5 inches (1 to 2 cm). Too little water and the smoke stays hot. Too much and you get splashback against your lips.
Test it before you load a bowl. Inhale with an empty bowl and listen for a light bubbling sound. If water hits your mouth, pour some out.
Do You Need a Screen?
No, but a screen makes cleanup easier. Without one, small pieces of flower and ash drop into the water and cloud it fast. A pack of brass screens costs a few dollars and lasts months.
If you forget a screen, a small piece of unlit flower placed at the bottom of the bowl does the same job. Skip broken glass, foil, or paper.
Do You Need to Grind Your Weed?
Yes, if you want an even burn. Finger-broken nugs create air pockets, and air pockets mean uneven toasting and a harsh finish. A cheap 2-piece grinder handles it in seconds.
Cleaning Supplies You Should Keep
Bong water gets foul in a day, and resin coats the glass, holds smell, and cuts flavor. Clean your piece at least once a week with heavy use, or after every few sessions with light use.
- Isopropyl alcohol, 91% or higher
- Coarse salt (kosher or rock salt work well)
- Pipe cleaners for the downstem and percolators
- Hot tap water
- Paper towels or a clean drying rack
Shake salt and alcohol in the chamber, let it sit ten minutes, shake again, then rinse with warm water. Salt scours the glass without scratching it.
Common Mistakes New Bong Smokers Make
- Packing the bowl too tight. Air cannot move, and the hit feels like work.
- Filling water past the downstem. Splashback on the first pull.
- Lighting the whole bowl at once. You burn the greens and waste flower.
- Leaving water in the bong. Mold and bacteria grow within days.
- Using a dirty piece. Resin buildup makes every hit taste harsh.
- Skipping the carb or bowl pull. Smoke sits in the chamber and turns stale.
Can You Smoke a Bong Without Water?
You can, and people call it a dry pipe. It hits hot and rough because nothing cools the smoke. If you are out of water, take small hits and expect more throat burn.
Is There Anything Else You Need?
Grab a glass of water, a snack, and somewhere comfortable to sit. Cannabis can hit harder through a bong than through a joint, so start with a small bowl. Set a limit before you start, especially if you are new to smoking or new to a high-THC strain.
What About the Weed Itself?
Bong hits work with flower, hash, and some concentrates, but not with everything. Vape cartridges and edibles need their own devices. If you buy flower at a dispensary, ask the budtender about moisture content and grind consistency.
For legal flower in the US, bring a valid ID. Federal law sets 21 as the minimum purchase age, and every legal state checks it. Look for lab-tested flower with a harvest date on the label.
Where to Get the Gear and the Flower
Head shops and dispensaries carry bongs, screens, and lighters. Eden Cannabis sells legal flower online and in store, and staff can point you to a strain that grinds well and burns even.
Bring a government ID. Legal cannabis sales in the US require proof of age 21 or older.
FAQ
What do you need to smoke a bong?
A bong, water, ground cannabis, a lighter, and a flat surface. A screen, grinder, and cleaning supplies make the process smoother but are optional.
How much weed goes in a bong bowl?
Most bowls hold 0.1 to 0.3 grams. Start near 0.1 grams if you are new to bongs, since a bong delivers more smoke in one hit than a joint.
Do you put ice in a bong?
Some bongs have an ice pinch. Ice cools the smoke, though it also increases condensation and cleaning. Cold water in the base gives a similar effect with less mess.
Can you smoke a bong without a screen?
Yes. A screen only keeps ash out of the water. Many smokers skip it and clean the piece more often.
How often should you change bong water?
Every session, or at minimum once a day. Old water grows bacteria and makes every hit taste used.
Is a bong better than a joint?
A bong filters some tar and particles through water, and it burns no rolling paper. It still sends smoke to your lungs, so it carries the same respiratory risks as any inhaled cannabis.
