Cannabis Keychain Pipe: The Short Answer
A cannabis keychain pipe is a hand pipe with a loop, ring, or hole at one end that takes a keyring. Most models run 2 to 3.5 inches long and hold 0.1 to 0.3 grams of ground flower per bowl. Common materials are metal, glass, silicone, and wood. Many models have a cap or slide lid that covers the bowl and keeps ash and smell inside. Metal and silicone models survive pocket carry. Glass models break when dropped on concrete.

Parts and Specs
- Bowl: 8 to 14 mm across on most keychain sizes, 0.1 to 0.3 g capacity.
- Air path: 2 to 4 inches.
- Mouthpiece: 6 to 12 mm opening.
- Cap or slide lid: standard on metal and silicone models.
- Attachment: split ring, carabiner clip, or swivel loop.
Materials
Metal
Aluminum and stainless steel. Weight runs 20 to 60 grams. Aluminum heats fast and cools fast. Steel holds heat and scratches less. Anodized finishes last longer against keys.

Glass
Borosilicate glass, 15 to 40 grams. Glass adds no taste of its own. Glass chips and cracks on impact. A padded pouch or hard case cuts breakage.
Silicone
Food-grade silicone, 10 to 30 grams. Silicone flexes and resists drops. Many silicone models take a glass or metal insert. The insert is the part that gets hot, not the body.

Wood
Maple, walnut, and cherry, 25 to 50 grams. Wood insulates, so the outside stays cooler than metal. Wood absorbs resin and takes burn marks. Do not soak wood in alcohol.
How to Use
- Grind flower into 2 to 3 mm pieces.
- Fill the bowl and leave 1 mm of space at the top. A packed bowl pulls harder.
- Hold flame near the bowl edge, not in the hole. Draw over 3 to 5 seconds.
- Cover the bowl with a finger or the cap between draws. This limits smoke loss.
- Tap ash out after each session. Resin sets in 24 to 48 hours.
Cleaning
Metal and glass: soak in 91% isopropyl alcohol for 30 to 60 minutes, scrub the bowl with a brush or pipe cleaner, rinse with warm water, then dry. Silicone: warm water and dish soap, or alcohol for heavy resin. Wood: scrape the bowl with a wood pick and wipe the inside. Clean a daily pipe every 3 to 7 days. Resin narrows the air path, and draw gets harder.
US Legal Notes
Federal law lists cannabis as a controlled substance, and 21 U.S.C. 863 covers drug paraphernalia. States with legal cannabis license pipes for legal use. The purchase age is 21 in adult-use states. Medical rules vary by state. Resin in a bowl changes the legal category in most jurisdictions, so an empty pipe and a used pipe are not the same item to law enforcement. Check state and city rules before carrying one in public.
Travel
Do not fly with a used pipe. TSA screens bags, and a pipe with resin falls under federal law. Keep a pipe at home for flights. In a car, store it in a closed container in the trunk, away from the cabin and the driver.
Safety
Smoke irritates the lungs. The CDC links cannabis smoke to coughing, wheezing, and bronchitis. Metal and glass parts reach temperatures that burn skin. Let a pipe cool for 1 to 2 minutes before you touch the bowl. Do not share a pipe with someone who is sick, and clean between users.
