Kief - hybrid
When you grind flower, the grinding will cast off some dust or powder. It will gather on your fingers or cast off into trays of grinders. This residue includes the debris from trichomes, those bulbous glands found on every surface of a cannabis plant. It’s those wispy white hairs loaded with THC. Kief makes a fine joint material or packed into a bowl or used in a bong. But veteran smokers mix the powder with their smoking leaves or add it to tobacco. You should remember kief has potency, so you should hold your breath with each draw and space out your puffs.
