// Definition
Any cannabis extraction method that avoids chemical solvents, relying instead on mechanical separation techniques such as ice water agitation (bubble hash), heat and pressure (rosin), dry sifting, or static electricity. Solventless products are prized for purity and full-spectrum expression.
// From the Episode
Across multiple 420 episode discussions, solventless extraction was framed as the gold standard for preserving the plant's true expression. Bubbleman reflected on introducing water hash in 1998-1999 when people would literally lose consciousness from the unfamiliar potency. Adam Ill predicted the future would move toward even less intervention - possibly electrostatic separation in the field. Cherry Blossom cited processing over a million grams of bubble hash in four years as testament to the scale of modern solventless operations.
