Smoke Grenade Rust: Craft Cost, Turrets, Duration & Gun Powder Trick (2026)

The Smoke Grenade is the one grenade in Rust that does no damage at all. You pull the pin, throw it, and a few seconds later there is a big wall of grey smoke that nobody can see through. Not players, not auto turrets, not CCTV cameras. That makes it one of the most useful cheap tools in the game for raids, monument runs and fights in the open.

It is also the best scrap to gun powder trade in Rust. A smoke grenade costs 5 scrap at the Outpost and recycles into 21 gun powder. This smoke grenade Rust guide covers the craft cost, how long the smoke lasts, what it blocks and what it does not, where to buy and loot them, the recycling trick and the best ways to use smoke on a raid.

What Is the Smoke Grenade in Rust?

The smoke grenade is a thrown tool, not an explosive. The in-game description says it “produces a large cloud of opaque greyish white smoke”, and that is all it does. There is no blast, no fire and no damage to players, doors or deployables. What you get instead is cover you can carry in your pocket.

Anyone looking into the cloud sees only grey, and anyone standing inside it is blind too. Automated defences that need line of sight, like the auto turret, lose their target. That is why you see smoke at every stage of a wipe: crossing open ground at a monument, hiding a locked crate hack, covering the door while you place C4, and blinding a roof camper while your team pushes.

Smoke grenades were added in August 2018. Back then you could only buy them at the Bandit Camp. Today they are a normal Workbench 2 blueprint and one of the cheapest items in the Outpost vending machines.

How to Craft a Smoke Grenade in Rust

The smoke grenade is not a default blueprint. Put one in a Research Table with 40 scrap, or unlock it on the Workbench 2 page of the tech tree. Then craft it at a Workbench 2 from:

• 35 Gun Powder, which is 70 sulfur and 105 charcoal.
• 50 Metal Fragments.

Each one takes 10 seconds, or 5 at a Workbench 3. A stack of three costs 210 sulfur, less than two beancans. In practice most players never craft them, because buying them at the Outpost for 5 scrap is far cheaper than farming the sulfur. Our Rust crafting calculator works out bigger batches if you do want to craft.

How Long Does a Smoke Grenade Last?

Put the grenade on your hotbar, select it and throw it like any other grenade. About a second after it lands the canister starts pouring out smoke, and within a couple of seconds the cloud is big enough to hide a whole group. Most tests put the full cloud at roughly 45 seconds. The last part is thin and patchy, so plan on a bit over half a minute of solid cover from one grenade.

Three things to remember:

• It does no damage. You can drop it at your own feet safely.
• Bullets go straight through. Smoke blocks vision, not projectiles. A player who knows where you are can still spray into the cloud and hit you.
• It hides you, not your sound. Footsteps, reloads and gun shots still give you away. Keep moving inside the cloud.

Smoke Grenades vs Auto Turrets and Traps

This is the smoke grenade’s best use. The auto turret needs a clear line of sight to shoot, and a smoke cloud between you and the turret breaks it. If the turret itself sits inside the cloud it cannot target anything at all. CCTV cameras are blinded the same way and just show grey to whoever is watching.

Smoke does not help against everything:

The catch with turrets is timing. They lock on again the moment the smoke clears, so throw the next grenade before the first one fades, not after. Smoke buys time, it does not kill the turret. Pair it with a few F1 grenades or explosive ammo if the turret has to go.

How to Use Smoke Grenades on a Raid

• Smoke the door before C4. Placing a timed explosive charge leaves you standing still for a second. One or two smokes on the door stop defenders on the roof from picking you off.
• Blind turret windows. Throw one smoke per turret before you peek a window or hallway. Bases with turrets on every floor need a full stack.
• Cross open ground. Runways at the Airfield, the open yard at Launch Site and the walk up to a raid base are where most players get shot. A line of smokes gives you a corridor.
• Hide the locked crate. A locked crate takes 15 minutes to hack. Smoke on the crate makes it much harder for a third party to snipe you off it.
• Defend with it too. If raiders are firing rockets from a hill, smoke between them and your base blocks their view of where to aim. Defenders on the roof can smoke the ground so the raiders cannot see each other.

Where to Get Smoke Grenades in Rust

The easiest way to get smoke is to buy it. The Extra 1 vending machine at the Outpost sells one smoke grenade for 5 scrap, and it restocks fast. Loot drops are rare:

Loot chances are per container from the Facepunch wiki loot tables, so treat them as a bonus. If you need smoke for a raid, buy it.

The Smoke Grenade Gun Powder Trick

This is the reason smoke grenades sell out on every server. A smoke grenade has 35 gun powder in its recipe and you buy it for 5 scrap. Recycle it and you get most of that gun powder back with no sulfur farming at all:

So do not recycle them inside the Outpost. Buy a load, walk to the nearest monument recycler and you get 50% more gun powder than in the safe zone. The recycler tiers come from the Power Trip update, where powering the grid and the red Power Plant recycler raise the yield. 21 gun powder for 5 scrap is about 42 sulfur worth for 5 scrap, which beats almost any other way to spend spare scrap. The full breakdown is in our gun powder guide.

Smoke Grenade vs 40mm Smoke vs Supply Signal

Three items in Rust make smoke, and they do very different things:

Never throw a supply signal for cover. The purple smoke is easy to spot from across the map, and the plane overhead tells every player nearby where you are.

Smoke Grenade Tips

• Throw before you need it. The cloud takes a second or two to build. Smoke first, then move.
• Re-smoke early. Turrets and players can see again the moment the cloud thins, so throw the next one at around 30 seconds.
• Keep moving. Players can still shoot blind into the cloud. Change direction inside it and do not stand where it started.
• Carry a stack. Three smokes take one slot and cost 15 scrap. They are cheap insurance on any monument run.
• Use the enemy’s smoke. If someone smokes their push, spray the edge of the cloud where they have to come out.
• Recycle what you do not use. Spare smokes are 21 gun powder each at a powered monument recycler.
