By now, you’ve probably seen them in your local store or on social media — colorful cans of Delta-8 THC drinks promising a mellow buzz and a new way to unwind. But what exactly are these “drinkables,” and are they really as harmless as they look?

We asked Godfrey Pearlson, MD, director of Olin Neuropsychiatry Research Center at Hartford HealthCare’s Institute of Living, to break it down for us.

1. First thing’s first: What is Delta-8 THC?

Most people are familiar with Delta-9 THC — it’s the main compound in marijuana that gets you high. Delta-8 THC is a close cousin. It’s chemically similar and can still make you feel high, just typically less so.

But here’s where it gets tricky. Delta-8 is made from legal hemp-derived CBD through a chemical process. That puts it in a legal gray area — not exactly legal, not exactly illegal.

“Delta-8 is outlawed in 13 states, but available in others,” explains Dr. Pearlson. “It hasn’t been approved or evaluated by the FDA for safe use, so there’s very little oversight. And worse, the concentrations of THC stated on the labels are often inaccurate, so you can’t always be sure what you’re getting.”

In short? Just because it’s on a store shelf doesn’t mean it’s been proven safe.

2. Here’s how it works.

Traditionally, THC needs fat to be absorbed by the body — think edibles like brownies or butter-based candies. But recently, scientists figured out how to “micro-encapsulate” THC so it can dissolve in water. That’s what makes Delta-8 sodas and other drinks possible.

It’s clever science, but don’t let the fun packaging fool you.

“People need to realize this is still THC,” says Dr. Pearlson. “Even though it’s in a soda can, it’s not like drinking a regular soft drink.”

3. Is it safe?

It’s the million-dollar question — and right now, the science just isn’t there.

“Because Delta-8 is so new, there are virtually no scientific publications on it,” says Dr. Pearlson. “We assume the risks are similar to Delta-9 THC, including intoxication, cannabis use disorder, increased risk of schizophrenia in adolescents, and problems during pregnancy.”

In terms of harm, THC ranks lower than alcohol on global drug harm scales. But that doesn’t make it safe.

“You shouldn’t drink Delta-8 if you’re pregnant, under 18, or plan to drive,” he adds.

4. What can go wrong?

Besides the legal murkiness and lack of regulation, side effects can include anxiety, paranoia and disorientation — especially if you overdo it.

“Because the high from drinkables takes time to kick in, people might think it’s not working and keep drinking more,” warns Dr. Pearlson. “That can lead to a much more intense, or even dangerous, experience than they were expecting.”

And remember — Delta-8 products are often mislabeled. Without FDA oversight, that “10mg” on the can hasn’t been vetted.

5. There might be healthier options available.

If you’re thinking about swapping alcohol for Delta-8 drinks, consider your goals.

“They’re two different drugs with very different effects on the brain,” says Dr. Pearlson. “Some people may prefer the effects of THC to alcohol, but again, there’s no good research comparing the two head-to-head.”

The good news is that drinkables are safer for your lungs than smoking. Just don’t combine Delta-8 drinks with alcohol or other substances — the effects may multiply rather than add.

“If you’re looking for a healthy alternative to alcohol, there are probably better places to start. Mocktails are becoming increasingly popular, making it easy to enjoy social events without any pressure to drink. If you’re looking for a calming beverage to relax after work, herbal tea might be an option,” says Dr. Pearlson.

If you’re going to try it…

Dr. Pearlson offers these tips:

  • Start low, go slow. Begin with a single can or serving and give it time to take effect.
  • Understand what you’re taking. THC in any form comes with risks. Be prepared for significant anxiety or paranoia, and make sure you’re in a safe place before trying it.
  • Keep it away from kids. The cans often look like regular soda and could be easily mistaken.
  • Don’t drive. Even if you feel fine, THC can impair your ability to operate a vehicle.
  • Don’t assume it’s harmless. Just because it’s legal (ish) and comes in a bubbly can doesn’t mean it’s risk-free.

Bottom line? Delta-8 drinks might seem like the next trendy way to chill, but proceed with caution — and stay informed.
