Cannabis Hash: What It Is and How to Use It
Cannabis hash is pressed trichomes with 20% to 60% THC. Learn how it's made, how to smoke it, how to store it, and how it compares to kief and rosin.
To smoke cannabis hash, crumble a piece about the size of a peppercorn, place it on a metal screen in a pipe or bong, or mix it with a little flower, then draw a gentle flame near the hash without torching it directly. Hash is concentrated resin, so it burns hotter and slower than flower and delivers more THC per hit. Start with one small hit and wait 10 to 15 minutes before taking more.
Hash, short for hashish, is made by collecting and pressing trichomes, the resin glands that hold most of the cannabinoids in cannabis. That concentration means hash usually tests higher in THC than the flower it came from. It also burns differently because it is dense and resinous, so it needs airflow and steady, low heat rather than a quick hard flame.
Solid chunks smother themselves and waste material. A loose, crumbly texture gives you an even burn and a smoother hit.
Beginners should aim for about 10 to 25 mg of THC, which is often a single small hit or a fraction of a peppercorn-sized piece. Hash can be two to five times stronger than flower, so the amount you would normally use of bud can be too much. Wait at least 15 minutes before deciding whether to take another hit.
Any inhaled combustion creates tar and carbon monoxide, and hash smoke is no exception. Vaporizing at lower temperatures reduces those byproducts while still releasing cannabinoids. People with respiratory conditions should talk to a doctor before inhaling any cannabis product.
Keep hash in an airtight glass jar away from heat, light, and air. Cool, dark storage at around 60 to 70 F preserves terpenes and keeps the resin from drying out or turning brittle.
