A one-hitter is a term to describe a small, slender smoking device that is often shaped and colored to mimic the look of a cigarette. Users often have a little stash box the one-hitter fits in, sometimes with the spring-activated lid that pops it up when you open it. Then it’s easy to grab your one-hitter and cram it into the other section where you’ve got some ground-up flower to pack the bowl and light up just like you would a cigarette. A one-hitter is sometimes called a bat, chillum, or a “oney”, and hold a small amount of weed used for discreet, on-the-go smoking sessions. They hold less weed but are easier and more discreet to use than a pipe (bowl).
