To make a doob tube for travel, cut a wide plastic straw or clean cigar tube a bit longer than your pre-roll, seal one end, slide the joint inside tip-first, then seal the other end so it cannot shift or rattle. Add an odor barrier and a label, and you have a light, crush-resistant case that drops into a pocket or dopp kit.
Waterproof Travel Tube for Cannabis: What Actually Matters
A doob tube is simply a rigid, narrow tube sized to hold one joint. You can buy them, but making one takes about five minutes and costs almost nothing. The builds below use items most people already have at home.

What a Travel Doob Tube Needs to Do
- Keep the pre-roll straight so the wrapper does not crack.
- Protect the twisted tip and the filter end from crushing.
- Slow air exchange so the joint does not dry out in a day.
- Cut odor enough that it does not announce itself inside a bag.
- Stay slim enough for a pocket, glovebox organizer, or toiletry pouch.
No homemade tube does all five perfectly. A straw tube is light and cheap. A screw-cap tube handles odor and crush protection better. Choose based on how long you will be away and how far you are going.

Method 1: Plastic Straw Doob Tube
This is the fastest option and the one most people mean when they search for how to make a doob tube for travel.
- One wide smoothie straw or reusable silicone straw
- Scissors
- Tape, either electrical or painter's tape
- A cotton ball or a scrap of tissue
- Optional: a strip of Mylar from a coffee bag
- Pick a straw with an inner diameter just wider than the joint so the pre-roll slides in without force.
- Cut it about an inch longer than the joint.
- Seal one end. Flatten the last half inch, fold it over twice, then wrap it with tape.
- If you seal the end with heat instead, hold the flattened tip with pliers and touch it to a flame for about a second. Melted plastic gives off fumes, so do that step outdoors or skip it.
- Let the end cool fully before anything goes inside.
- Slide the joint in tip-first so the twisted end stays intact.
- Pack a small piece of cotton at the open end to stop rattling, then flatten and tape the second end.
- Wrap the finished tube in a strip of Mylar for extra odor control.
Method 2: Cigar Tube or Test Tube
A plastic or aluminum cigar tube with a cap is basically a doob tube already. Rinse it, dry it fully, and check that the joint fits without bending. Drop a small piece of foam or cotton in the bottom, add the pre-roll, then top it with another small piece so nothing slides. Screw the cap on and write the strain or date on a piece of tape on the outside. Glass test tubes with cork or screw caps work the same way and clean up easily.
Method 3: Pill Bottle With a Foam Insert
This version carries two or three joints and is the sturdiest of the three.
- Use a clean, dry pill bottle. Never reuse a bottle that still has a prescription label on it, since mix-ups with medication are a real risk.
- Cut a piece of craft foam, cork, or pool noodle to fit inside the bottle.
- Press the pre-rolls into the foam to form channels, or cut slots with a craft knife.
- Set the joints into the slots, close the cap, and tape the lid shut for travel.
How to Make It Travel-Ready
- Odor: A tube alone is not smell-proof. Put it inside a smell-resistant pouch or zip bag along with the Mylar wrap.
- Moisture: Air exchange dries a joint out. A tight seal slows that down, which is all a tube is meant to do.
- Rattle: Cotton or foam at both ends keeps the joint from knocking around and cracking the wrapper.
- Label: Mark the tube with contents and date. It saves you from opening three tubes at a rest stop.
- Kids and pets: If children or animals are around, use a child-resistant container instead of a straw tube and store it out of reach.
Check the Rules Before You Pack
Cannabis remains illegal under federal law in the United States, and carrying it across state lines is prohibited even when both states have legalized it. Airports, federal land, and international borders follow federal rules. Check the destination state's possession limit, stay within it, and never take cannabis across an international border. A doob tube keeps a joint intact. It does not change the law where you are standing.
How Long Does a Doob Tube Keep a Joint Fresh?
A sealed tube slows drying for a few days, which is enough for a weekend trip. It is a carrier, not long-term storage. For a week or more, keep pre-rolls in an airtight glass jar and load the tube the morning you leave.
