April 20 is the cannabis world's unofficial holiday, and San Diego has historically celebrated it with pop-up markets, dispensary deals, and community gatherings. In 2026, the addition of a licensed consumption lounge at Sessions By The Bay gives the day a new dimension: for the first time, San Diego cannabis consumers have a legal, social venue to gather, share, and celebrate on 4/20 without the uncertainty of where or how to consume.

Here is a look at what the San Diego cannabis event calendar looks like throughout the year, what to expect at the landmark Sessions By The Bay, and how to participate in the growing culture around legal cannabis in the South Bay and beyond.

4/20 Weekend at Sessions By The Bay

Sessions By The Bay's grand opening weekend in April 2025 fell on the 4/20 holiday, and the result was a packed, celebratory debut that set the tone for everything that followed. In 2026, the venue is positioned as the anchor for San Diego's 4/20 celebration, with extended lounge hours, curated menus, and events that bring together brands, artists, and cannabis enthusiasts from across the region.

The rooftop bar at Sessions By The Bay offers one of the most scenic settings in the county for an outdoor cannabis experience, with sweeping views of San Diego Bay. On major event days, the venue typically features live music or DJ sets, specialty menu items, and collaborations with cannabis brands that want direct access to engaged consumers in a legal, licensed setting.

Cannabis Pop-Up Markets

Beyond 4/20, pop-up markets have become a regular fixture in the San Diego cannabis calendar. These events typically feature licensed dispensaries and brands offering product samples, merchandise, and educational programming in curated settings. Some pop-ups focus on specific categories like cannabis and wellness or cannabis and art, while others are general markets that bring together a broad range of licensed operators.

Pop-up markets must comply with all state and local regulations around cannabis sales and consumption. Legitimate events will have licensed vendors, age verification at entry, and clear signage about consumption rules. If an event lacks these basics, approach with caution.

Brand Launch Events and New Product Drops

As the San Diego cannabis market matures, brands are increasingly using the region as a launch market for new products and partnerships. Sessions By The Bay has hosted several brand launch events since its opening, leveraging its combination of dispensary retail space, lounge, and dining to create immersive brand experiences that media and consumers remember.

For consumers, these events often mean access to limited-edition products before they hit the general menu, direct interaction with brand representatives who can answer detailed product questions, and promotional pricing on featured items. Following your favorite dispensary and brands on social media is the best way to stay informed about upcoming launch events.

Cannabis and Wellness Events

One of the fastest-growing segments of the San Diego cannabis event calendar is the intersection of cannabis and wellness. Yoga classes, meditation sessions, sound baths, and nutrition workshops that incorporate or acknowledge cannabis are increasingly popular. These events draw a demographic that might not identify as a traditional cannabis consumer but is curious about cannabis as a wellness tool for stress, sleep, and recovery.

These events typically take place at wellness studios, private venues, or in the outdoor spaces that San Diego's climate makes available year-round. Check community boards, cannabis-friendly event platforms, and the social media accounts of local cannabis brands for information about upcoming wellness programming.
