The STIGMA

The 2026 STIGMA Halloween run has separate evening sessions on October 22, 23 and 24 at Thunder Studios in Long Beach. Each session runs from 8 p.m. to midnight and has its own RSVP page. Weedmaps describes a four-chamber test of speed, perception, instinct and reaction with a different brand lineup across the three dates. No earlier edition or annual return is claimed.
