What a chillum is

A chillum is a straight tube with a wide bowl and a narrow mouthpiece. Most are 4 to 6 inches long. Clay and terracotta are traditional materials. Glass, stone, wood, and metal versions also sell. The bowl holds about 0.3 to 0.5 grams. You load from the wide end and draw from the narrow end. There is no carb. Most chillums have no screen, so a glass or metal screen, or a small plug, keeps herb and ash out of the mouth.

Advantages of a chillum

• Cost. Clay and glass chillums sell for $5 to $20 at most shops.
• Size. A 5-inch chillum fits in a pocket.
• One piece. No O-rings, no downstem, no water to spill.
• No rolling. Loading takes a few seconds.
• Dose per bowl. A 0.3 gram load gives a short session.
• Durability. Metal and stone versions resist drops.
• Smoke path. A joint burns between puffs. A chillum burns while you draw.

Disadvantages of a chillum

• Heat. The flame sits close to the herb and the smoke path is short. The first hit can be hot.
• No filtration. There is no water chamber and no percolator.
• Ash pull-through. Screens help, but ash and resin can reach the mouth.
• Cleaning. Unglazed clay is porous and traps resin. Glass and metal clean with isopropyl alcohol. Clay does not.
• Heat on the hand. Tubes under 4 inches get hot near the bowl.
• Sharing. Mouth contact passes saliva. Many users keep a chillum personal.
• Reloads. A group session needs a reload after each bowl.
• Combustion. Burning plant matter makes tar, carbon monoxide, and irritants. A chillum does not filter these.

Chillum compared with a joint and a one-hitter

A joint holds 0.5 to 1 gram and burns between puffs. A chillum holds less and burns while you draw. A one-hitter is a small metal or glass pipe with a bowl of about 0.1 to 0.2 grams. A chillum bowl is larger. A one-hitter loads one dose at a time. A chillum needs a screen and a longer draw.

How to use a chillum with less irritation

1. Fit a screen or a small glass plug.
2. Grind coarse. Fine grind pulls through.
3. Hold the tube at about 45 degrees.
4. Light the edge of the bowl, not the center.
5. Stop when ash reaches the screen.
6. Clean glass and metal with isopropyl alcohol after each session.

Legal note for US buyers

Chillums count as drug paraphernalia under many state laws. Sale and possession rules differ by state. Cannabis remains illegal under federal law. Check state law before you buy.
