Guide to Attending Local Cannabis Expos and Finding Vendor Booths
Discover how to make the most of local cannabis expos, from identifying the right ones to locating vendor booths.
The Emerald Cup is the best cannabis event for connoisseurs. It is a judged flower competition first and a festival second, which means exhibitors compete on aroma, flavor, and effect instead of booth size. The event runs at the Sonoma County Fairgrounds in Santa Rosa, California, and pulls in small craft farms that rarely show up at brand-heavy trade expos.

Three other events round out the list for anyone who judges weed by terpenes and cure rather than by packaging.
How we ranked these cannabis events
Ranking came down to four signals: whether flower is judged blind, how many craft and single-source farms attend, whether consumers can actually sample or buy, and how much of the floor is devoted to education versus swag.
- Judging format: blind panels and lab-tested entries outrank pure popularity contests.
- Grower density: small-batch cultivators per square foot of floor space.
- Consumer access: sample passes, consumption zones, and direct sales.
- Programming: terpene talks, solventless demos, and cultivar history panels.
1. The Emerald Cup (top pick)
The Emerald Cup has run since 2003 and built its reputation on blind judging of sun-grown flower. Entries are scored by a panel that includes breeders, hash makers, and longtime cultivators, and winners often sell out within days of the announcement.

Who it is for
Connoisseurs who care about living soil, heirloom genetics, and full-term outdoor flower. If you can describe the difference between a 2010 OG cut and its modern crosses, this is your room.
What to expect
A large consumption area, hash and rosin vendors, and panels on cultivation and policy. The crowd skews toward Northern California growers, so bring cash and a plan for the Santa Rosa heat.
2. Hall of Flowers
Hall of Flowers is a curated trade show with consumer-facing days in Palm Springs and Santa Rosa. Brand curation is the point: buyers walk a tightly edited floor instead of a hundred booths of the same vape hardware.
Consumer days give enthusiasts access to new drops before they hit dispensary shelves. Check the schedule, because trade-only days are not open to the public.
3. Spannabis (Barcelona)
Spannabis is the largest cannabis expo in Europe and the best excuse for a connoisseur trip abroad. The floor leans heavily toward hash, rosin, and European seed companies, with a separate competition for concentrates.
Expect a dense international crowd and equipment vendors mixed with breeders. Cannabis laws in Spain differ from US rules, so read the local regulations before you travel.
4. High Times Cannabis Cup
The Cannabis Cup now runs as state-by-state judging competitions rather than one giant festival. Judges buy a kit, score entries, and results are published by category, which makes it the most accessible entry point for a first-time connoisseur.
The trade-off is geography. You get a curated box of local flower instead of a weekend on a show floor, so pick a state with a strong craft scene such as California, Oregon, or Colorado.
Comparison at a glance
- Best overall: The Emerald Cup, for judged flower and craft grower density.
- Best for new product discovery: Hall of Flowers, for curated brand debuts.
- Best international: Spannabis, for hash and European genetics.
- Best low-effort option: High Times Cannabis Cup, for at-home judging kits.
Which events to skip
Pure business conventions such as MJBizCon are built for operators, not for tasting. Headshops and vape hardware expos also tend to have thin flower representation. Save your ticket money for events where cultivators are the main attraction.
FAQ
Are cannabis events legal to attend?
Yes, in jurisdictions that allow adult use, though rules on onsite consumption and sales vary by venue and state. Always confirm the event's consumption policy before booking travel.
Can you buy flower at a connoisseur event?
Some events include licensed dispensary partners and allow direct sales, while others are sample-and-learn only. Gifted or shared samples may be restricted depending on state law.
Which event is best for solventless hash?
Spannabis and the Emerald Cup both have deep rosin and hash representation. The Emerald Cup's concentrate categories make it the stronger pick for US-based hash heads.
What should a first-timer bring?
Cash, a water bottle, a notebook for cultivar names, and a sealed container for anything you purchase. Comfortable shoes matter more than you think at a multi-hall expo.
