Rosin is a solid form of resin that is obtained from pine trees and other coniferous plants. It is produced by heating and distilling the resin extracted from these trees. Rosin has a wide range of uses, including in music (for string instruments like violins and cellos), in sports (to improve grip in activities like gymnastics and weightlifting), and in various industrial applications.

In the context of weed rosin refers to a solventless concentrate that is made by applying heat and pressure to cannabis flower or hash to extract the cannabinoids and terpenes. This process results in a sticky, sap-like substance that is rich in THC, CBD, and other compounds found in cannabis. Rosin is popular among weed enthusiasts for its purity, potency, and versatility.

Consumers may use rosin by dabbing it (vaporizing and inhaling the concentrate), adding it to jointsor bowls for an extra kick, or incorporating it into edibles or topicals. As with any cannabis product, it's important to use rosin responsibly and in moderation to avoid potential adverse effects.
