A one-hitter is a small, discreet cannabis smoking pipe designed to be loaded with just enough flower or concentrate for a single inhalation or “hit.” One-hitters provide ultra-portability and stealthiness, often resembling pens, cigarettes or other innocuous items used for concealment. Their straight-through airflow design omits a carb. For best results when smoking flower, lightly grind a small amount to expose surface area and inhale slowly. Resin gradually builds up and can clog one-hitters over time, so regular cleaning with alcohol and pipe cleaners maintains open airflow and effectiveness. Portable and convenient, one-hitters allow for quick, discreet hits on the go with minimal odor. They also help moderate dosage and conserve weed. However, their tiny size necessitates repacking constantly.
