Hash

Hash (hashish) is one of the oldest forms of cannabis concentrate, traditionally made by collecting and pressing the resinous trichomes (kief) from cannabis flowers. Modern hash includes traditional pressed hash, bubble hash (ice-water extracted), and dry-sift hash. Hash typically tests 30-60% cannabinoids.

Example: Bubble hash from this brand makes excellent solventless rosin starting material.

Etymology: Arabic 'hashish' (حشيش), meaning 'grass.'
