Quick Answer: A hash hole is a pre-roll with a rope of concentrate, usually rosin or hash, running through the center of the flower. As it burns, the core melts into the surrounding bud and leaves a hollow, donut-shaped ash ring, which is where the name comes from. Hash holes hit harder and burn slower than a regular joint. In Florida, adults 21 and older can buy hemp-derived versions online, such as Mellow Fellow’s THCa hash hole pre-rolls.

Key Takeaways

• A hash hole is a joint built around a center strip of concentrate, most often solventless rosin or hash.
• The core burns slower than the flower around it, which creates the signature donut-shaped ash ring.
• Hash holes are stronger per gram than flower-only joints because every pull draws through concentrate.
• Kief and hash both come from trichomes. Kief is loose powder; hash is pressed or processed into a solid.
• Hemp-derived hash holes are sold online to Florida adults 21 and older, but hemp rules change, so check the current law before buying.

What Is a Hash Hole?

A hash hole is a type of infused pre-roll. The roller lays a thin rope of concentrate down the middle of a bed of ground flower, then wraps the flower around it so the concentrate sits in the exact center of the joint. Most premium hash holes use solventless hash rosin, a concentrate pressed from cannabis using only heat and pressure.

The format is young. LA-based cultivator Shant Damirdjian, founder of Fidel’s Hash Holes, is credited with rolling the first one in March 2018, according to LA Magazine. The name stuck because of what happens when you smoke one: the concentrate melts into oil as it burns and soaks into the flower, leaving a hole in the middle of the ash. You will also see them called donut joints or hash donuts.

Mellow Fellow’s own guide to what a hash hole is walks through the build in more detail.

Hash Hole vs. Regular Joint vs. Infused Pre-Roll

All three look similar in the pack. The difference is where the concentrate sits, if there is any at all.

For a side-by-side from the brand’s point of view, see Mellow Fellow’s breakdown of a hash hole vs. a regular joint.

Types of Infused Pre-Rolls

“Infused pre-roll” is an umbrella term. Hash holes are one of four common builds:

• Hash hole: a rope of rosin or hash runs through the center.
• Kief-coated: loose trichome powder coats the outside of the joint, usually over a sticky layer.
• Distillate-dipped: the joint is coated in cannabinoid oil, often rolled in kief afterward.
• Infused flower: concentrate is blended into the ground flower throughout the joint.

Because the concentrate is sealed inside, a hash hole tends to deliver its potency more evenly from first pull to last than a coated joint, where much of the concentrate sits on the outer layer.

Kief vs. Hash: What’s the Difference?

Kief and hash both come from trichomes, the tiny resin glands on cannabis flowers that hold most of the plant’s cannabinoids and terpenes. The difference is what happens after collection.

Rosin, the core most hash holes use, is a solventless form of hash made by pressing. Mellow Fellow covers the topic in more depth in its kief vs. hash guide.

How Strong Are Hash Holes?

Hash holes are among the strongest pre-roll formats because they pair a full flower fill with a concentrate core. Exact strength depends on the cannabinoids in the flower and the core, so the only reliable way to compare products is the lab report.

Here is what the published certificates of analysis (COAs) show for Mellow Fellow’s 2g THCp hash holes, each tested as a finished product by ACS Laboratory, an ISO/IEC 17025 accredited lab:

Delta-9 THC tested below the lab’s limit of quantitation in all three, and each batch passed pesticide, heavy metal, mycotoxin, residual solvent, and microbial screening. For the THCa line, Mellow Fellow lists 920mg of THCa per 2g Daydream hash hole on the product label.

Two things make these numbers matter more than they look:

• THCp is unusually potent. In the study that first isolated it from cannabis, THCp bound to the brain’s CB1 receptor about 33 times more strongly than Delta-9 THC in lab testing (Citti et al., Scientific Reports, 2019).
• THCa becomes Delta-9 THC when lit. Heat converts THCa into Delta-9 THC through decarboxylation, so a THCa hash hole delivers a traditional THC high once smoked (acidic cannabinoid decarboxylation review). OutSFL’s explainer on whether THCA gets you high covers this in detail.

A 2g hash hole is a lot of product for one person. Treat it as a shared joint or a multi-session smoke.

How to Smoke a Hash Hole

Hash holes smoke like a joint, but the concentrate core changes the technique slightly.

1. Toast the end evenly. Rotate the tip in the flame until the whole end glows, so the core starts melting with the flower around it.
2. Take slow, gentle pulls. Hard draws overheat the core and can pull oil to the paper.
3. Rest between pulls. Give the cherry a few seconds so the core melts at the same pace as the flower.
4. Rotate if it runs. If one side burns faster (canoeing), turn the joint so the slow side faces down, or touch the fast side with a damp fingertip.
5. Pace yourself. Concentrate effects build quickly. Take a few pulls, wait several minutes, and decide from there.

Are Hash Holes Legal in Florida?

Hemp-derived hash holes can be sold to adults 21 and older in Florida. Florida law bars the sale of inhalable or ingestible hemp extract products to anyone under 21, and the state limits marijuana to registered medical patients, so dispensary hash holes require a medical card. OutSFL’s guide to whether THCA is legal in Florida covers the state rules in more detail.

Federal rules are changing. Public Law 119-37 rewrites the federal definition of hemp to a total-THC standard and caps finished hemp products at 0.4mg of total THC per container. The changes are phased in, starting with converted cannabinoids such as Delta-8 THC and most commercial THCp, then the rest of the definition, which covers THCa products, according to the Hemp Law Group. Congress can still revise these rules, so check the current status and the brand’s shipping page for your state before ordering.

Will a Hash Hole Show Up on a Drug Test?

Yes. THCa converts to Delta-9 THC when smoked, and standard drug tests look for THC metabolites without telling hemp and marijuana apart. Delta-8 and THCp products can also trigger a positive result. If you are tested for work or any other reason, skip hash holes altogether.

Frequently Asked Questions

What is a hash hole?

A hash hole is a pre-roll with a rope of concentrate, usually rosin or hash, running through the center of the flower. The core melts as the joint burns, leaving a hollow, donut-shaped ash ring. Hash holes are stronger per gram than flower-only joints.

Why is it called a hash hole?

The name comes from the hole left in the ash. As the concentrate core burns, it melts into oil and soaks into the flower around it, leaving a donut-shaped ring of ash with a hollow center. That is also why hash holes are sometimes called donut joints.

Are hash holes stronger than regular joints?

Yes. A hash hole adds a concentrate core to a full flower fill, so every pull draws through concentrate as well as flower. Mellow Fellow’s 2g THCp hash holes, for example, test at 446mg to 523mg of total cannabinoids per joint.

What is the difference between kief and hash?

Kief is the loose, powdery trichome heads sifted from dry cannabis. Hash is trichomes pressed or separated into a solid concentrate using heat and pressure or ice water. Rosin, the core of most hash holes, is a solventless pressed form of hash.

Are hash holes legal in Florida?

Hemp-derived hash holes can be sold to adults 21 and older in Florida, and dispensary hash holes require a medical marijuana card. Federal hemp rules are changing, so check the current status before you buy.

How long does a hash hole take to smoke?

Longer than a regular joint of the same size. The concentrate core burns slower than flower, and most hemp hash holes come in 2g sizes, so one hash hole is usually enough for a group or several sessions.

How do you keep a hash hole from canoeing?

Toast the end evenly before your first pull, take slow pulls, and rest between them. If one side starts burning faster, rotate the joint so the slow side faces down, or dampen the fast side lightly with a fingertip.

Can you make a hash hole at home?

Yes. Roll a thin rope of rosin or hash, lay it down the center of a bed of ground flower, and roll the paper tightly around it so the core stays centered. Mellow Fellow’s how to roll a hash hole guide shows each step.

The Bottom Line on Hash Holes

A hash hole is the most concentrated way to smoke a joint: flower outside, rosin or hash inside, and a slow burn that leaves a donut of ash. For Florida adults, hemp hash holes such as Mellow Fellow’s THCa and THCp hash holes are the ship-to-your-door option. Read the COA, start with a few pulls, and check the current hemp rules where you live.
