What a hash hole is

A hash hole is a cannabis cone with a core of hash running down the center. Flower forms the outer wall. Hash, most often bubble hash, dry sift, or rosin, sits in a channel in the middle. When lit, the hash melts and the flower burns around it. The cherry forms a ring of resin that looks like a donut. Another name for the build is a donut joint.

What you need

Steps to roll one

  1. Grind the flower to a medium cut. Fine dust clogs airflow. Large chunks leave gaps.
  2. Pack a small amount of flower into the cone base. Tamp it with the packing tool. This layer keeps the hash from blocking the airway.
  3. Add flower in thin layers. Leave open space down the center.
  4. Drop the hash into the channel. A thin snake of hash works better than one solid ball. A ball traps heat and stops the draw.
  5. Cover the hash with flower. Fill until the top sits about 3 mm below the paper rim.
  6. Press a skewer down the middle from the top to the base. Pull it out. This opens the air path.
  7. Twist the paper closed. Let the joint sit for 10 to 15 minutes so the flower and hash settle.

Ratio of flower to hash

A 3:1 build by weight is common. That means 1 g of flower with 0.33 g of hash. Builds above 1:1 burn uneven and need relights. Rosin runs at a lower melt point than flower burns, so a rosin core can seep through the paper. Bubble hash and dry sift hold their shape better.

How to light and draw

Toast the tip with a hemp wick or a torch held 2 to 3 inches away. Keep the flame off the hash core. Pull with a steady draw. The hash melts first, then the cherry spreads out from the flower. Rotate the joint as you pull. If one side of the paper stops burning, that side has a gap in the pack.

Storage

Keep the joint in a glass jar at 62% relative humidity. Store rosin in the fridge and add it just before you smoke. A rolled hash hole holds for about a week in a sealed jar.

Safety notes

Combustion creates tar, carbon monoxide, and benzene. The CDC notes that smoking cannabis can harm the lungs. Hash carries a higher THC level than flower, so a hash hole delivers more THC per puff than a plain joint. Take one or two puffs and wait 10 minutes before the next. THC can raise heart rate and cause anxiety or paranoia in some users.
