How the Missouri Cannabis Events Calendar Works
The Missouri cannabis events calendar is a community-powered resource. While I do spend time regularly searching for and adding events myself, many listings also come directly from:
- Event hosts
- Venues
- Promoters
- Community members
Submitting your event is always free — and it helps keep the calendar accurate, useful, and growing.
New Service for Venues & Recurring Hosts
With the increase in event volume — especially around 4/20 — it is easier for events to be missed if they are not consistently submitted.
This optional service is designed for venues and hosts who want:
- Their website or social pages checked regularly
- Events identified and added consistently
- Less manual work and less risk of missing dates
To be clear: submitting your own events is still 100% free.
