These Cheech and Chong's Up In Smoke grinders are branded to match the movie as we roll up on 40 years since the iconic film hit the screens. The four part design uses diamond shaped teeth to make sure your herbs are finely ground without getting squashed. The sifter screen in the bottom will collect your keef as you use it meaning you'll build up a hidden gold mine. Available in a variety of colors, this is a great way to commemorate these two legendary stoners.
