Celebrate 420 at Voodoo 420 Market, a cannabis-friendly block party presented by Swade at Atomic in St. Louis. Join us on April 19, 2026 from 1PM to 6PM for an afternoon packed with live music from Sean Canan’s Voodoo Players, local vendors, great food, and a dedicated consumption lounge. Whether you’re here for the music, the community, or to explore what local vendors have to offer, this is your chance to experience one of the most unique 420 celebrations in the city. This is a free event, so come out, bring your friends, and spend the day with us at Atomic.
