Infused pre-rolls are pre-rolled joints that pair cannabis flower with a concentrate such as kief, hash, rosin, distillate or THC diamonds. The concentrate can sit inside the cone, coat the outside or both. Because concentrates carry far more THC than flower, an infused joint usually hits harder than a standard one. Here's what's inside, how makers build them, how to roll your own and how to enjoy one at a careful pace.
What Makes a Pre-Roll "Infused"
A standard pre-roll is ground flower in a paper cone. An infused pre-roll adds a second ingredient that boosts potency, flavor or both. That might be a cannabinoid-rich concentrate, a resin such as rosin, or cannabis-derived terpenes for aroma. The flower still does most of the burning.

How Makers Infuse: Inside, Outside or Both
There are three basic builds:
- Inside the cone. Kief or hash is blended into the flower, or a sticky concentrate is layered in or laid down the center as a thin rope before the cone is packed.
- On the outside. The finished joint is brushed with oil or distillate and rolled in kief, which gives it a dusty, golden coat.
- Both. A concentrate core plus a coated exterior. These builds pack the most concentrate.
Inside infusions tend to burn more evenly because the paper stays clean. Outside coatings look striking, but they can get sticky, drip and make the burn harder to control.
Infusion Types
Here's what makers typically use:
| Infusion | What it is | Good to know |
|---|---|---|
| Kief | Loose trichome heads sifted from dried flower | Blends in evenly; our kief guide explains how it's collected |
| Hash and bubble hash | Kief pressed into a solid, or trichomes separated with ice water | Earthy flavor and a solid potency boost |
| Wax | A soft, opaque solvent extract | Usually layered or roped inside |
| Rosin | Resin pressed from flower or hash with heat and pressure, no solvents | Rich flavor; a solventless option |
| Diamonds | Crystalline THCA, often paired with a terpene-rich sauce | Very high potency |
| Distillate | Refined cannabinoid oil with little natural flavor | Common for outside coatings |
| Moon rocks | Buds coated in oil and rolled in kief | Sometimes crumbled into a joint for a dense, heavy hit |
CBD-Infused vs. THC-Infused
Most infused pre-rolls use THC-rich concentrates, but CBD-rich versions exist. Keep in mind that a CBD infusion adds CBD, not THC. If the flower is THC-rich, the joint still carries all of that THC. For a lower-THC experience, look for a joint where both the flower and the infusion are CBD-dominant. Michigan labels list THC and CBD content, so compare those numbers rather than relying on the product name.
Concentrate-Infused vs. Terpene-Infused
This one trips people up.
- Concentrate-infused pre-rolls add a cannabinoid-rich concentrate, so the THC per joint goes up.
- Terpene-infused pre-rolls add aromatic terpenes, which change the smell and taste but add essentially no THC.
A terpene-infused joint is close to a regular joint in strength. Check the label to see which kind you're holding.
Why People Choose Infused Pre-Rolls, and Who Should Wait
Experienced consumers reach for them for a few reasons: more potency per joint, a concentrate's flavor without a rig, and the convenience of something ready to light. Potency is the big difference. In Washington State's legal market, an analysis of millions of sales found that concentrates averaged 68.7% THC, compared with 20.6% for flower. Swap even a little flower for concentrate and the total climbs fast.
Here's simple math for a 1-gram joint:
| Joint | Flower | Concentrate | Total THC |
|---|---|---|---|
| Standard | 1 g at 20% THC | None | About 200 mg |
| Infused | 0.8 g at 20% THC | 0.2 g at 70% THC | About 300 mg |
These are illustrations, not product specs, and you won't inhale every milligram. The jump is still real.
If you're new to cannabis, haven't used it in a while or aren't sure how THC affects you, start with a standard pre-roll instead. The same goes if a regular joint has ever left you uncomfortably high, since an infused one will likely feel stronger. Our pre-roll buyer's guide can help you choose one. Skip cannabis if you're pregnant or breastfeeding, and check with a clinician if you take medications.
At Home: Making an Infused Joint
Adults 21 and older can make their own in Michigan for personal use. Keep it simple and start light. A kief joint is the easiest version:
- Grind your flower and measure out a small pinch of kief for your first try.
- Lay out a paper and add a crutch, a small rolled filter tip.
- Spread a thin layer of flower, sprinkle the kief down the middle, then cover it with more flower.
- Roll, tuck and seal as usual. Our joint-rolling walkthrough covers each step in detail.
- Pack the end lightly and twist it closed.
For a stickier concentrate such as wax or rosin, roll a thin rope between sheets of parchment paper and lay it down the center before you roll. Use clean hands or a dab tool, never a lighter or torch. Heating concentrate near an open flame can scorch it or ignite the paper before you're ready.
If you carry cannabis in Michigan, the limit is 2.5 ounces, and no more than 15 grams of that may be concentrate.
Responsible Use: Pacing, Sharing, Uneven Burn
- Pace yourself. Take one or two small puffs, then wait. Inhaled THC takes effect within minutes and peaks in about 20 to 30 minutes, so give it time before deciding on more. An infused joint doesn't need to be finished in one sitting.
- Share thoughtfully. Tell friends it's infused before you pass it, since a regular-joint pace can be too much. Never share with anyone under 21.
- Expect an uneven burn. Rotate as you draw, relight gently and let it rest between puffs.
- Pick the right place. Enjoy it on private property where it's allowed. Using cannabis in public isn't allowed in Michigan, and neither is smoking it in a vehicle on a public road.
- Don't drive. Stay put or get a ride.
- Store leftovers safely. Make sure a half-smoked joint is fully out, then keep it in a sealed container, away from heat and out of reach of kids and pets.
