Solvent-based products are often more efficient and cost-effective (while solventless concentrates are becoming more common because of their purity), natural flavor profiles, and perceived safety. Some of the products usually crafted with solventless extraction include rosin (rosin jam), bubble hash, and kief. Rosin pressing, for example, involves applying heat and pressure to squeeze out cannabinoids, resulting in a potent and flavorful product without any solvent residue.
