An infused pre-roll looks like an ordinary joint, but it is a very different smoke. Along with the flower, it carries an extra layer of concentrate: oil, kief, hash or crystals, blended through the joint or coated on the outside. The result is a much stronger, slower-burning pre-roll that has become one of the fastest-growing formats in Canada. This guide explains what infused pre-rolls are, the main types, how they are made, how strong they are, how to smoke one properly, how to pick a good one, and how the infused pre-rolls we carry compare.
Infused pre-rolls at a glance
| What they are | Pre-rolled joints that contain cannabis concentrate as well as flower |
|---|---|
| Common infusions | Distillate or CO2 oil, kief, hash, live resin, THCA crystals |
| Strength | Much stronger than a regular joint of the same size |
| Burn | Slower and hotter; can run or “canoe” if lit unevenly |
| Flavour | Unflavoured (tastes of the flower and concentrate) or flavoured with added terpenes |
| Who they suit | Experienced smokers, or groups sharing one joint |
What is an infused pre-roll?
A regular pre-roll is ground flower rolled in paper, ready to light. An infused pre-roll adds a concentrate to that flower. Because concentrates are several times stronger than bud, even a small amount changes the experience completely. A typical infused joint delivers far more THC per puff than a regular joint, and it usually lasts longer because oils and resins burn slower than dry flower.
Types of infused pre-rolls
Oil or distillate infused
The flower is mixed or coated with THC distillate or a full-spectrum oil, such as CO2-extracted oil. Distillate adds strength; full-spectrum oil adds strength plus more of the plant’s original flavour.
Kief infused or kief coated
Kief, the loose trichome powder from cannabis flowers, is blended into the flower or rolled onto the outside of a joint that has been lightly coated in oil. Kief-coated joints have that frosty, golden look.
Hash infused
Hash, or loose hash powder, is mixed through the flower. Solventless hash is made without chemical solvents and keeps a rich, traditional flavour.
Diamond and live resin infused
THCA crystals or live resin are threaded through the centre of the joint. These are usually the strongest and most expensive infused pre-rolls.
Moon rock style
Moon rocks are buds dipped in oil and rolled in kief. “Moonrock” pre-rolls borrow that idea by combining flower, oil and kief in one joint.
How infused pre-rolls are made
There are two basic approaches. The first blends the concentrate through the ground flower before it is rolled, which gives the most even burn and strength from first puff to last. The second places concentrate on the inside or outside of the joint: a line of oil or crystals down the centre, or oil painted on the paper and rolled in kief. Outside coatings look impressive but burn less evenly. Many quality makers prefer to blend throughout, and product descriptions will often tell you which method was used.
Terpenes and flavour
Infused pre-rolls come in two flavour styles. Unflavoured joints taste of the flower and the concentrate itself; hash-infused ones lean earthy and spicy, while oil-infused ones taste of the strain the oil came from. Flavoured joints add terpenes or flavouring for tastes like strawberry, caramel or vanilla ice cream. Flavour is personal: if you want to taste the cannabis, choose unflavoured; if you want something sweeter and smoother, a flavoured option is the way to go.
Are infused pre-rolls stronger?
Yes, much stronger. Regular flower is commonly around 18% to 28% THC, while distillate is commonly 80% or more and kief often 40% to 60%. Adding even a small share of concentrate pushes the overall strength of the joint well above flower alone. That is why infused pre-rolls are usually labelled for experienced smokers.
Infused vs regular pre-rolls
- Strength: infused joints are far stronger per puff.
- Burn time: infused joints burn slower, so one lasts longer or goes further between friends.
- Flavour: regular joints taste of the flower; infused joints taste of the flower plus the concentrate or added flavour.
- Value: infused joints cost more each, but deliver more THC per joint.
How to smoke an infused pre-roll
- Toast the tip evenly. Rotate the joint while you light it so the whole end catches at once. This prevents canoeing, where one side burns faster than the other.
- Take slow, gentle pulls. Infused joints burn hotter, and big hits can be harsh.
- Pause between puffs. Let the effects build before you keep going, especially the first time you try a new product.
- Do not rush to relight. Oils can make the cherry smoulder slowly; give it a moment before reaching for the lighter again.
- Share it. One infused joint is often plenty for two or three people.
What to look for when buying an infused pre-roll
- What it is infused with. A good product page tells you exactly what is inside: distillate, full-spectrum oil, kief, solventless hash or crystals. Vague descriptions are a warning sign.
- How the infusion is applied. Concentrate blended through the whole joint burns more evenly than a coating on the outside.
- The flower underneath. Infusion adds strength, but the base flower still decides much of the flavour and smoothness. Look for the flower grade if it is listed.
- Flavoured or unflavoured. Decide whether you want to taste the cannabis or a sweeter added flavour.
- Size. Compare weights, such as 1 g or 1.2 g, when you compare prices.

What are the strongest infused pre-rolls?
Generally, joints infused with THCA crystals, distillate or a mix of oil and kief are the strongest, and hash-infused joints sit a little lower while offering a more traditional flavour. Our Cosmic Rock and Moonrock Canada specialty pre-rolls are both described on their product pages as much stronger than a plain joint and made for experienced smokers.
How to store infused pre-rolls
Keep them in their tubes or packaging, in a cool, dark place. Heat can make the oils inside soften and seep into the paper, and dry air makes the flower burn faster and harsher. Do not leave them in a car or a sunny window, and keep them away from children and pets.

FAQ
What is an infused pre-roll?
A pre-rolled joint that contains a cannabis concentrate, such as oil, kief, hash or crystals, as well as flower.
Are infused pre-rolls stronger?
Yes. The concentrate pushes the overall THC far above a regular joint, so take slow puffs and wait between them.
What are the strongest infused pre-rolls?
Those infused with THCA crystals, distillate or oil plus kief are usually the strongest. Hash-infused joints are a little milder with a more traditional flavour.
What’s the difference between a regular pre-roll and an infused pre-roll?
A regular pre-roll is flower only. An infused pre-roll adds concentrate, so it is stronger, burns slower and usually costs more per joint.
How do you stop an infused pre-roll from canoeing?
Toast the tip evenly while rotating the joint, take gentle pulls, and avoid relighting too quickly. If one side runs, touch the flame briefly to the slower side.
Are infused pre-rolls worth it?
If you want a strong, long-lasting joint with no rolling, yes. If you are new to cannabis, a regular pre-roll is a gentler place to start.
How long does an infused pre-roll last?
Smoking time depends on size and how fast you pull, but infused joints burn noticeably slower than regular ones, so a 1 g to 1.2 g infused pre-roll often lasts through several sessions if you put it out between them. Unopened, stored cool and dark in its tube, it keeps well for months.
