Happi has quietly racked up 13 industry awards and over 1,000 five-star reviews while most people in the THC drink space are still arguing about Cann vs. Wynk. Their seltzers hit the 5-10mg range with genuinely interesting flavors and functional ingredients like lion's mane and reishi mushrooms. Here's whether the hype matches the product.
What Happi Gets Right
The flavor range is outstanding. Raspberry Honeysuckle, Mango Sweet Basil, Lime Wild Mint, Blood Orange Ginger, Passionfruit Magnolia. These aren't just "fruit plus carbonation." The botanical pairings give each flavor a complexity that most THC seltzers lack. The Mango Sweet Basil received a 93-point rating from Tastings in 2025.
Happi also goes deeper than basic THC. Their functional lines include Happi Glow (daytime, with adaptogenic mushrooms) and Happi Nightcap/Dreams (evening, with calming compounds). The idea is that different times of day call for different formulations, and Happi builds each product around that premise rather than offering one formula in multiple flavors.
Dose options run from 5mg (standard) to 10mg (their Drift and Glow Up lines), giving you flexibility without needing to stack cans.
Where Happi Falls Short
Pricing is premium. An 8-pack runs $32.99 on ShopKanna, roughly $4.12 per can. That's competitive with Wynk but more expensive than Cycling Frog's 6-pack at $24.99.
The functional mushroom angle is interesting but unproven. Lion's mane and reishi have some promising research, but the doses in a single seltzer can are modest. Happi doesn't make therapeutic claims, which is the right move, but buyers should understand the mushroom addition is more about synergy than standalone effects.
No CBD in most formulations. If you prefer a balanced THC:CBD ratio like Just Chill or Cycling Frog, Happi is THC-forward.

Best For
Flavor-forward drinkers who want more than basic seltzer. People interested in functional ingredients alongside THC. Anyone who's tried the mainstream brands and wants something more interesting.
Not Ideal For
Budget shoppers (price per can is above average). People who want a THC:CBD balanced experience. Minimalists who prefer simple, three-ingredient seltzers.
The Bottom Line
Happi is the most interesting THC seltzer brand we've reviewed. The flavor creativity and functional formulations set it apart from the crowd. If you've been underwhelmed by basic seltzers, Happi's botanical pairings deliver something genuinely different.
