Hashish (Hash)

Hash (short for hashish) is a type of cannabis concentrate. It's made by collecting and pressing the sticky, crystal-like stuff that grows on the buds and leaves of the cannabis plant. This sticky stuff is called resin, and it comes from tiny glands called trichomes. Trichomes kind of look like mushrooms under a microscope.

These little trichomes are what hold most of the THC, the main chemical that makes people feel high when they use cannabis.

⚠️ Just so you know: This guide is meant to help people understand how hash is made — not to encourage its use. Cannabis is illegal or age-restricted in many places, and it's not recommended for anyone under 18.

Why Make Hash?

Even after harvesting cannabis, some parts like leaves and small bits (called "trim" or "skuff") still have some trichomes on them. These parts don't taste great when smoked, but they can be used to make hash, so nothing goes to waste. Making hash is a way to get the most out of a cannabis harvest.

Different Ways to Make Hash

1. Flat Screening (Simple, Cheap, but Messy)

This method uses a fine screen (like a window screen) and a flat surface like glass or a mirror.

  • Dry the skuff, but don't make it too crumbly.

  • Rub it gently over the screen.

  • The tiny trichomes fall through the screen onto the glass.

  • Collect the powder and press it into hash.

👉 This method is easy and cheap, but the hash might contain some plant bits.

2. Drum Machine (Better Quality, More Expensive)

This is like a small clothes dryer with a screen inside. It gently tumbles the skuff until the trichomes fall off.

  • Put the dry skuff inside the drum.

  • Let it spin for a while (a few minutes to an hour).

  • The trichomes fall out as powder.

  • Collect the powder and press it into hash.

👉 This method makes cleaner hash but requires buying or building a machine like the Pollinator, which is still popular today.

3. Ice Water Hash (Also Called "Bubble Hash")

This method uses ice water and a blender to knock the trichomes off.

What you need:

  • Blender

  • Ice

  • Cold water

  • Skuff

  • Coffee filter or fine mesh

  • A big jar

Steps:

  1. Blend skuff, water, and ice until it's frothy (like a smoothie).

  2. Filter the mix into a jar.

  3. Let it sit in the fridge so the trichomes sink.

  4. Pour off the water.

  5. Filter out the trichomes and dry them.

This method is super popular in 2025 because it makes clean hash without using chemicals. It's called bubble hash because it often bubbles when you heat it — a sign of purity.

Using Bubble Bags (For Cleaner Hash)

A more advanced version of the ice water method uses Bubble Bags — special bags with screens that filter trichomes by size.

You need:

  • At least two buckets

  • Ice, cold water, skuff

  • A hand mixer

  • Bubble Bags (different screen sizes)

How it works:

  • Mix everything with the hand mixer in one bucket.

  • Pour into the bags layered in another bucket.

  • Each bag catches a different quality of trichomes.

  • Scoop out and dry the trichomes to make different grades of hash.

👉 Pro tip: The finest screen (25 microns) gives you the strongest but smallest amount of hash. The average yield is about 10 grams of hash from 200 grams of skuff.

Pressing the Hash

Once you have the powdery trichomes, you need to press them into a solid block or ball.

How to press hash:

  • Make sure the powder is completely dry (moist hash can get moldy).

  • Wrap it in plastic and wet newspaper.

  • Heat it gently in a frying pan or with a hair straightener.

  • Use a rolling pin or something heavy to press it flat.

  • Let it cool and dry.

Congratulations — now you've made your own hash!

In Summary:

  • Hash is made from the trichomes on cannabis plants.

  • You can make it by rubbing, tumbling, or using cold water and filters.

  • The cleaner the method, the better the hash.

  • Always dry and press the powder before storing it.

  • ✅ Today, bubble hash is one of the most popular and clean ways to make hash. It's safe (no chemicals), high-quality, and used worldwide.
