About 420 Expo

420 Expo is free and open to the public all three days of the event. It includes over 100 merchants, designated outdoor smoking areas, food trucks, celebrity appearances, live music, educational sessions, and panels. There is a rigid 21+ rule in place at the 40 Expo. In light of this, the 420 Expo has you covered for a fun weekend of all things marijuana-related, whether you enjoy "wake and bake," consider yourself a casual user or a cannabis connoisseur, want to learn more about cannabis and CBD, or just want to check out some dope vendors, eat some good food, and listen to some great music. Looking to meet and take pictures with some of your favorite cannabis-friendly celebrities? Yeah, they're working on that too! For those who need to satisfy their hunger, they also have their extremely cool Munchy Court. Not to mention, this show will draw some of the best viewers on the East Coast.
