Delta 8 vs. Delta 9 THC: What's the Difference?
Quick takeaway: Delta 8 and Delta 9 THC are nearly identical molecules. The only difference is where one double bond sits. Delta 9 is the main THC compound in cannabis and is generally considered the stronger of the two. Delta 8 occurs in hemp only in trace amounts, so most Delta 8 on the market is made by chemically converting CBD. Both are intoxicating, both can cause a positive drug test, and both are regulated differently from state to state. This guide walks through how they compare on strength, source, lab testing, drug tests and legal status, so you can make an informed choice.
If you've shopped for hemp-derived THC in the last few years, you've almost certainly seen both Delta 8 and Delta 9 on the shelf. The names sound interchangeable, and the marketing around them can be confusing. Some brands describe Delta 8 as "THC lite." Others call hemp-derived Delta 9 the "real thing." Neither shorthand tells the whole story.
At Royal Remedies, we've made both. We sold Delta 8 products for years before focusing entirely on hemp-derived Delta 9 gummies. So this isn't a theoretical comparison for us. It's a question our customers have asked us thousands of times.
This guide is about how the two compounds differ: chemistry, strength, production, testing and regulation. It is not medical advice, and everyone responds to THC differently.

The Chemistry, in Plain Language
THC stands for tetrahydrocannabinol. "Delta 8" and "Delta 9" describe where a double bond sits in the molecule's carbon chain: at the 8th position for Delta 8, and the 9th position for Delta 9. Otherwise, the two molecules have exactly the same atoms. Chemists call compounds like this isomers.
That one small shift matters. It changes how strongly the molecule binds to CB1 receptors, the cannabinoid receptors in the brain and nervous system that are responsible for THC's intoxicating effects. Delta 9 binds more strongly, which is the main reason it feels stronger at the same milligram amount.
Stability
The double bond position also affects stability. Delta 8 is more chemically stable and less likely to break down over time. Delta 9 can slowly degrade, especially with heat, light and air, and part of it can convert into CBN. This is one reason we recommend storing Delta 9 gummies in a closed jar in a cool, dry place out of direct sunlight.
Strength: How Do They Compare?
Delta 9 is generally considered the stronger of the two. People who have tried both often describe Delta 8 as milder or more "mellow," and Delta 8 is commonly described as roughly half to two-thirds as strong as Delta 9 at the same dose. That's a rough rule of thumb, not a precise conversion, and individual experiences vary widely.
You can see this difference in how products are labeled. Delta 8 gummies often contain 25mg, 50mg or more per piece. Hemp-derived Delta 9 gummies are usually 5mg or 10mg. Royal Remedies gummies contain 10mg of Delta 9 each.
If you're switching from Delta 8 to Delta 9
This is the most important practical point in this guide. Don't assume your usual Delta 8 dose translates directly. If you're used to a 25mg Delta 8 gummy, a 25mg Delta 9 serving could feel much stronger than you expect. Start with half of one of our 10mg gummies (about 5mg), wait at least 90 minutes, and adjust from there. Our serving size guide walks through it step by step.
How Each One Is Made
Delta 9: extracted and refined
Hemp naturally contains small amounts of Delta 9 THC. Manufacturers extract cannabinoids from hemp, then refine that extract into a high-purity Delta 9 distillate. Because the THC content of distillate can be measured precisely, it can be dosed into an exact amount per gummy. Our gummies are made with hemp-derived Delta 9 distillate. For more on how distillate differs from other extracts, see Live Resin vs. Distillate.
Delta 8: mostly converted from CBD
Delta 8 is a different story. Hemp contains so little natural Delta 8 that extracting it directly isn't practical at scale. Instead, nearly all Delta 8 sold today is made by chemically converting CBD using acids, solvents and heat. When done carefully, the result is mostly Delta 8. When done poorly, the process can leave behind residual solvents, acids, or other byproducts that aren't fully understood.
That conversion step is the main reason Delta 8 has drawn so much attention from regulators. The FDA has issued consumer warnings about Delta 8 products, citing concerns about manufacturing practices, labeling and products that appeal to children. Several states have restricted or banned Delta 8 specifically because it is produced through chemical conversion.
Lab Testing: What to Look For
Whichever cannabinoid you choose, a Certificate of Analysis (COA) from an independent, accredited lab is the most reliable way to know what's actually in the product. A good COA should:
- Match your batch. The batch or lot number on the COA should match the one on your package.
- Come from an accredited lab. Look for ISO/IEC 17025 accreditation.
- Show a full cannabinoid profile. It should list Delta 9, Delta 8 and other cannabinoids, with amounts per serving or per gram.
- Be recent. Testing dates should line up with when the product was made.
For Delta 8 products, it's especially worth looking for testing on residual solvents and other contaminants, since the conversion process can introduce them.
Not sure how to read a COA? Our guide How to Read a COA covers the four things to check. You can see the results for every Royal Remedies flavor on our Lab Results page.
Drug Tests
Both Delta 8 and Delta 9 can cause a positive drug test. Standard drug tests look for THC metabolites, the compounds your body produces as it breaks THC down. Delta 8 and Delta 9 produce very similar metabolites, and common screening tests generally can't tell them apart.
"Hemp-derived" on a label won't protect you on a test. If you're subject to drug testing for work, sports, the military or any other reason, avoid both. We go deeper in Will Delta 9 Show Up on a Drug Test?
Legal Status
Hemp-derived cannabinoid laws are complicated and changing quickly, at both the state and federal level. A few general points:
- Federal rules. Under the 2018 Farm Bill, hemp was defined as cannabis containing no more than 0.3% Delta 9 THC by dry weight. Federal hemp rules are scheduled to change in late 2026, which will affect many hemp-derived THC products.
- State rules. Many states have their own laws. Some restrict or ban Delta 8, some restrict hemp-derived Delta 9, some restrict both, and some set age, labeling or potency limits.
- Age. Royal Remedies sells only to adults 21 and older.
Because these rules vary and change, we only ship to states where we can deliver, and our checkout won't accept an address outside them. Learn more on our Shipping page. Nothing in this article is legal advice.
Which One Is Right for You?
That depends on what you're looking for, where you live, and how you respond to THC. A few practical considerations:
- If you want a predictable, measured experience, look for a product made with a well-tested distillate and clear milligrams per serving.
- If you're new to THC, start with a low dose of either, and be especially careful with Delta 9 because it's stronger per milligram.
- If you're coming from Delta 8, expect Delta 9 to feel stronger at the same number on the label.
- If lab testing matters to you, check for a batch-matched COA from an accredited lab before you buy.
Why Royal Remedies Makes Delta 9
We sold Delta 8 for years. Today we make one thing: hemp-derived Delta 9 gummies. We chose to focus on Delta 9 because it can be extracted directly from hemp and refined into a consistent distillate, which lets us measure every gummy to 10mg and test every batch.
Every jar contains 30 gummies, each with 10mg of hemp-derived Delta 9 THC. They're vegan, made with a pectin base instead of gelatin, naturally flavored, and colored with fruit and vegetable extracts. They come in four flavors: Super Strawberry, Mango Madness, Rowdy Raspberry and Mellow Melon. Meet the flavors.
Frequently Asked Questions
Is Delta 8 or Delta 9 stronger?
Delta 9 is generally considered stronger. Delta 8 is often described as roughly half to two-thirds as strong at the same dose, though individual experiences vary.
Is Delta 8 natural?
Delta 8 occurs naturally in hemp, but only in trace amounts. Nearly all Delta 8 sold today is made by chemically converting CBD.
Is hemp-derived Delta 9 the same as Delta 9 from marijuana?
The molecule is the same. The difference is the plant source and the laws it's sold under. Learn more in What Is Delta 9 THC?
Can I switch from Delta 8 to Delta 9?
Yes, but start low. Delta 9 will likely feel stronger at the same milligrams. Try half of a 10mg gummy and wait at least 90 minutes before taking more.
Will Delta 8 or Delta 9 show up on a drug test?
Both can. Standard drug tests detect THC metabolites and generally can't distinguish between Delta 8 and Delta 9.
How long do Delta 9 gummies take to kick in?
Usually 30 to 90 minutes, and sometimes up to 2 hours. See How Long Do Delta 9 Gummies Take to Kick In?
Is Delta 8 legal?
It depends on your state, and the rules are changing. Many states have restricted or banned Delta 8. Check your state's current laws before buying any hemp-derived THC product.
Why do Delta 8 gummies have more milligrams than Delta 9 gummies?
Because Delta 8 is milder per milligram, manufacturers typically use higher amounts to produce a comparable experience.
Does Royal Remedies still sell Delta 8?
No. We now focus entirely on hemp-derived Delta 9 gummies.
Final Thoughts
Delta 8 and Delta 9 are close chemical cousins, but they aren't interchangeable. Delta 9 is stronger per milligram and can be extracted and refined directly from hemp. Delta 8 is milder and is usually made by converting CBD, which is why testing and regulation get so much attention.
Whichever you choose, the same rules apply: buy from a brand that publishes batch-matched lab results, start with a low dose, give edibles time to work, and know your state's laws. If you're new to Delta 9, our beginner's guide is a good next read.
