Resin may refer to the dark to light brown substance which is scraped off the surface of the trichomes of a cannabis plant. Further, it is widely used to describe the by-product that sticks by the sides of a bowl or other cannabis holding pieces after smoking the product over a period of time. Some people scrap the resin off their paraphernalia, roll it into balls and smoke. It consists of tar, ash, carbon, and less potent cannabinoids, and is considered unhealthy for smoking.
A resin is a solid or highly viscous liquid that can be converted into a polymer. Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds insoluble in water, predominantly terpenes. Technically, resins should not be confused with gums, which consist predominantly of water-soluble polysaccharides, although these two terms are often interchangeable in the less formal context. Common resins include pine oleoresins, amber, hashish, frankincense, myrrh and the animal-derived resin, shellac. Resins are used in varnishes, adhesives, food additives, incenses and perfumes.

Resins protect plants from insects and pathogens, and are secreted in response to injury. Resins repel herbivores, insects, and pathogens, while the volatile phenolic compounds may attract benefactors such as predators of insects that attack the plant.
