When people talk about THC – you know, the part of cannabis that actually does something – they’re usually talking about Delta-9. It's the main active compound in cannabis that gives you that classic euphoric, relaxed, sometimes giggly feeling. But what exactly is it?

Let’s break it down.

So, What Is Delta-9?

Delta-9 (short for Delta-9-tetrahydrocannabinol) is the big-name cannabinoid in both cannabis and hemp. It’s the one responsible for the psychoactive effects, or the “high,” that cannabis is known for.

When you consume Delta-9, it interacts with your body’s endocannabinoid system (yes, that’s a real thing), specifically targeting receptors in your brain and nervous system that influence mood, memory, appetite, and more. Translation? It can make you feel lifted, relaxed, or just more tuned in to the moment.

Wait – Is This the Same THC That’s in Weed?

Yes. Delta-9 is THC. Same chemical structure, same effects, same everything. Whether it comes from cannabis or hemp, your body processes it the exact same way. The difference lies in how much of it is present and how it’s extracted.

How Do You Get Delta-9?

Delta-9 can be extracted from either hemp or cannabis. Cannabis plants naturally contain higher levels of Delta-9, but hemp plants (which are basically cannabis’ more chill cousin) contain enough to work with—if you know how to extract it properly.

Once extracted, Delta-9 can be infused into everything from edibles and gummies to tinctures, vape pens, and of course… seltzers. The beauty of hemp-derived Delta-9 is that it gives you the same vibe as cannabis-derived THC, but in a format that’s legal in more places—and often lighter, smoother, and more functional.

Why Delta-9 in a Seltzer?

Good question. A Delta-9 seltzer delivers a controlled, consistent, and fast-acting experience. Thanks to nano-emulsification (fancy term, we know), Delta-9 in liquid form is absorbed faster than traditional edibles, meaning you’ll feel the effects within about 15–30 minutes.

Plus, there’s no smoke, no sugar crash, and no next-day haze—just clean, crisp bubbles and good vibes.

The Bottom Line

Delta-9 is the real deal. Whether it’s coming from hemp or cannabis, it’s the same exact molecule doing the same exact job—delivering that classic THC experience in whatever form you enjoy most. At hi Seltzer, we just made it bubbly.

So next time you crack open a can, know this: you're not sipping on some knockoff. You're getting the good stuff—just in a chiller, lighter, and fully legal form.
