How to Fix a Cigar Burning Unevenly: Canoeing & Runs

You light up, settle in, and a few minutes later you notice it: one side of the cigar is racing ahead while the other lags behind. A cigar burning unevenly is one of the most common little frustrations for new smokers — but here's the reassuring part: it's almost always fixable right there in your chair, with nothing more than your lighter. Let's name the three types, figure out why they happen, and fix them.

The Three Kinds of Uneven Burn

An uneven burn shows up in three recognizable ways. Knowing which one you've got tells you how to fix it.

• Canoeing — one side burns faster than the other, leaving a long, lopsided shape like a hollowed-out canoe. The most common issue by far.
• Tunneling — the inside (the filler) burns faster than the outer leaf, so the cigar burns down the middle and leaves a hollow ring of unburned wrapper (the outer leaf) around the edge.
• Runs — a thin line of burn shoots ahead up the side of the wrapper, like a fuse running up the cigar.

All three boil down to one half of the cigar burning faster than it should. Fixing them means helping the slow part catch up.

Why Cigars Burn Unevenly

Before you fix it, it helps to know what caused it — so you can avoid it next time. There are three usual suspects.

1. An uneven light to start

This is the number one cause. If you don't toast the foot — the open end you light — evenly, the cigar starts life burning crooked and stays that way. A rushed or one-sided light almost guarantees a wonky burn. Taking your time getting a full, even glow before that first puff prevents most problems. If your lights tend to come out lopsided, our guide on how to light a cigar walks through doing it evenly.

2. Humidity that's off

A cigar that's stored too moist or too dry won't burn evenly. Too humid and it burns sluggishly, often canoeing or struggling to stay lit. Too dry and it can burn too fast and hot, encouraging runs. The sweet spot most people aim for is around 65–70% relative humidity — our cigar humidity guide covers how to hit and hold it. If a stick has dried out completely, rehydrating a dry cigar slowly can bring it back before you ever light it.

3. How it was packed and rolled

Sometimes it's just the cigar. If the filler is packed unevenly — denser on one side, looser on the other — the loose side draws more air and burns faster. Tunneling in particular often comes from a too-tight pack or from puffing too gently to keep the wrapper burning along with the core. There's not much you can do about the roll itself, but you can touch it up as you smoke.

How to Fix It with Your Lighter

Here's the actual repair. The principle is simple: apply heat to the part that's lagging behind to bring it level with the rest.

1. Find the slow side. Look at the burn line. The part that's furthest back is what you're correcting.
2. Touch up with the flame. Hold your lighter so the flame just kisses the slow-burning edge — you're toasting it, not roasting it. A few seconds is usually enough.
3. Don't scorch the wrapper. Keep the flame near, not jammed against the cigar, so you don't burn the outer leaf or leave a black mark.
4. Take a gentle puff. Once the lagging side is glowing, a slow puff evens everything out. Now the burn line should be roughly level again.

For tunneling, aim the flame at the unburned wrapper edge ringing the hollow center, toasting it until it catches up with the core. For runs, a quick touch-up to the rest of the burn line usually lets it even back out on its own.

How to Avoid It Next Time

A little prevention saves a lot of touching up:

• Light evenly and patiently. Most uneven burns are born at the foot.
• Don't puff too fast. Hard, rapid puffing overheats one side and throws off the burn (and makes the smoke bitter). Aim for a puff every 30–60 seconds.
• Store at the right humidity. A well-kept cigar simply burns better.
• Smoke out of strong breezes. Wind pushes the burn sideways and causes canoeing.
• Rotate the cigar occasionally so it's not always facing the same way.

The Recap

A cigar burning unevenly comes in three flavors — canoeing, tunneling, and runs — and all three trace back to lighting, humidity, or packing. The fix is the same idea every time: gently touch the lagging side with your lighter to bring it level, then take a slow puff. Light evenly, keep your cigars at the right humidity, and don't rush your puffs, and you'll see uneven burns far less often.
