The leftover, burnt material that builds up in pipes, bongs, and other smoking devices after repeated use. This “resin” is typically dark, sticky, and contains tar, ash, and small amounts of cannabinoids. Some people scrape and reuse it, though its quality and flavor are far inferior to fresh cannabis.
