Quick Answer
Delta-8 THC is a psychoactive cannabinoid that is chemically similar to delta-9 THC (the compound that causes marijuana’s “high”) but is usually made from hemp-derived CBD through a chemical conversion process. The FDA has not evaluated or approved delta-8 THC products for safe use in any context, and its legal status depends on your state and can change quickly. Before buying or using any delta-8 product, check your state’s current law and look for third-party lab testing.
Warning Signs That Need Immediate Attention
The FDA has received reports of serious reactions to delta-8 THC products, most often from food items like gummies and brownies. Seek emergency care or call Poison Control at 1-800-222-1222 if someone shows:
- Hallucinations or sudden confusion
- Repeated vomiting
- Tremors or loss of coordination
- Severe anxiety or panic
- Dizziness that doesn’t go away
- Loss of consciousness
Call 911 right away for any symptom that feels like an immediate danger to health. These reactions have happened in both adults and children, and delta-8 products should always be stored out of reach of kids and pets.
What Is Delta-8 THC?
Delta-8 THC (delta-8-tetrahydrocannabinol) is one of more than 100 naturally occurring cannabinoids in the cannabis plant. It occurs in only tiny amounts in raw hemp, so manufacturers typically convert hemp-derived CBD into concentrated delta-8 THC through a chemical process. This is different from simply extracting a cannabinoid that’s already abundant in the plant, and it’s a key reason regulators are paying close attention to how these products are made.
Delta-8 THC vs. Delta-9 THC: What’s the Difference?
Delta-8 and delta-9 THC are close chemical cousins. The name refers to the position of a double bond in the molecule’s carbon chain, which sounds technical but has real effects on how the compound behaves in the body.
- Delta-9 THC: The primary psychoactive compound in traditional marijuana. It produces the intoxicating “high” most people associate with cannabis.
- Delta-8 THC: Has psychoactive and intoxicating effects similar to delta-9 THC, according to the FDA, though many users report the effects feel different in intensity.
- Natural abundance: Delta-9 THC occurs in much higher natural concentrations in the cannabis plant. Delta-8 THC is naturally scarce and is usually lab-converted from CBD.
- Federal framing: Delta-9 THC is regulated based on concentration under federal hemp rules. Delta-8 THC’s legal status is less settled and varies more by state.
Because historical, real-world experience with cannabis mostly reflects naturally occurring cannabinoid levels, the FDA has noted that this experience can’t be reliably used to judge the safety of concentrated, lab-converted delta-8 THC products.
Is Delta-8 THC Legal?
Legal status here is jurisdiction-specific and changes over time, so treat this as a general starting point, not a final answer for your state. The 2018 Farm Bill removed hemp and its derivatives from the federal definition of marijuana, provided the product meets the legal hemp definition. That opened a gray area that many delta-8 products have been sold under. However:
- A number of states have passed their own laws that restrict, regulate, or ban delta-8 THC products, separate from federal hemp rules.
- State rules can change from one legislative session to the next, and enforcement varies by state and even by city.
- A product being sold online or in a store is not proof that it’s legal in your specific location.
Before purchasing, check your state attorney general’s office or state health/agriculture department website for the current rule where you live. Our Cannabis and Cannabinoid Science section covers related hemp and cannabinoid topics as we publish them.
Delta-8 THC vs. CBD vs. CBG vs. Delta-9 THC: Key Terms
These terms get mixed up often. Here’s a plain-language breakdown:
- CBD (cannabidiol): A non-intoxicating cannabinoid. It does not produce a “high.”
- CBG (cannabigerol): Another naturally occurring cannabinoid, generally found in smaller amounts in the plant, and typically marketed as non-intoxicating.
- Delta-8 THC: A psychoactive cannabinoid usually made by converting CBD, as described above.
- Delta-9 THC: The main psychoactive compound in traditional marijuana; also the THC form addressed by the federal hemp concentration limit.
- Full spectrum: Contains a wide range of the plant’s naturally occurring compounds, which may include trace THC.
- Broad spectrum: Contains multiple cannabinoids but is processed to remove detectable THC.
- Isolate: A single, purified cannabinoid with other plant compounds removed.
Safety Concerns With Delta-8 THC Products
The FDA has flagged several specific concerns about delta-8 THC products currently on the market:
- No FDA safety evaluation: Delta-8 THC products have not been evaluated or approved by the FDA for safe use in any context.
- Manufacturing chemicals: Converting CBD into delta-8 THC can involve household chemicals that may leave behind harmful byproducts if the process isn’t tightly controlled.
- Inconsistent manufacturing settings: Some products are made in uncontrolled or unsanitary conditions, raising contamination risk.
- Variable potency and labeling: Product formulations and stated concentrations can vary widely from one brand to the next.
- Adverse event reports: The FDA logged 104 adverse event reports tied to delta-8 THC between December 2020 and February 2022, and national poison control centers logged thousands of additional exposure cases in the same period, including cases involving children.
- Marketing that appeals to children: Products packaged as gummies, chocolates, and cookies can be mistaken for regular candy or snacks.
Checklist: Before You Buy Any Delta-8 Product
- Is delta-8 THC currently legal to buy and possess in my state?
- Does the seller provide a current, batch-specific Certificate of Analysis (COA) from an independent lab?
- Does the COA show tested THC concentration and check for contaminants like heavy metals, pesticides, and residual solvents?
- Is the packaging clearly labeled as containing THC, not disguised as ordinary candy or snack food?
- Is the product stored somewhere children and pets cannot access it?
- Have I talked to a healthcare provider if I take medication or manage a health condition?
Who Should Use Extra Caution
Because delta-8 THC is intoxicating and not FDA-evaluated, extra caution is warranted for:
- Anyone who is pregnant or breastfeeding
- Children and teens
- People taking prescription medications, who should ask a pharmacist or doctor about possible interactions
- People managing an existing health condition
- Pet owners, since animal poison control centers have reported rising accidental exposures
- Anyone planning to drive or operate machinery
This is general education, not medical advice. A qualified healthcare provider is the right resource for personal guidance, including any decision about starting, stopping, or changing a medication or supplement routine.
What the Evidence Does and Doesn’t Show
What’s established: Delta-8 THC is psychoactive and intoxicating. The FDA has documented real adverse events tied to delta-8 THC products, concentrated most heavily in food items like gummies. Manufacturing quality varies significantly across brands.
What’s still uncertain: There isn’t FDA-approved safety data on delta-8 THC for any use. Long-term effects, safe dosing ranges, and full interaction risks with medications haven’t been established through FDA review. Legal status is also actively evolving at the state level, so any specific legal claim can go out of date.
Frequently Asked Questions
Is delta-8 THC the same as marijuana?
No. Delta-8 THC is a specific cannabinoid, usually converted from hemp-derived CBD. Marijuana is a type of cannabis plant material that naturally contains higher levels of delta-9 THC along with many other compounds.
Will delta-8 THC show up on a drug test?
Standard THC drug tests are generally designed to detect THC metabolites broadly, and delta-8 THC can potentially trigger a positive result. Anyone concerned about drug testing should treat delta-8 use the same as delta-9 use for that purpose.
Is delta-8 THC safer than delta-9 THC?
This hasn’t been established. The FDA has not evaluated delta-8 THC products for safety, and its adverse event data shows real risks, including reactions serious enough to require emergency care.
How do I know if a delta-8 product is high quality?
Look for a current, batch-specific Certificate of Analysis from an independent lab that confirms both potency and the absence of contaminants. A brand that can’t produce this documentation is a red flag.
