 Delta-8 THC

What is Delta-8 THC?

The Cannabis Sativa plant contains hundreds of naturally occurring cannabinoids. The major cannabinoids in the plant are the psychoactive delta-9 THC and non-psychoactive cannabidiol (CBD). Delta-9 THC is the cannabinoid most responsible for producing the “high” from cannabis. Similarly, Delta-8 THC is a naturally occurring minor cannabinoid in the cannabis plant that is described as having half the “high” of delta-9 THC (marijuana).

Why is Delta-8 THC Poisoning Trending?

In 2021, CDC issued a health advisory regarding the increased availability of cannabis products containing delta-8 THC. These products may be sold legally in hemp or marijuana marketplaces and have been marketed as “weed light”. Delta-8 THC is in a number of products including edibles, extracts and vapes. FDA has not evaluated or approved delta-8 THC products for safe use. Since Delta-8 THC is found in such small quantities in the cannabis plant, it is often chemically made from CBD. As such, these products may contain other cannabinoids, terpenes, or chemical contaminants that are not on the product label.

As of June 30, 2024, Poison Centers have managed 1,194 Delta-8 THC related exposure cases.

From 2021 to 2024, Poison Centers have managed 9,182 Delta-8 THC related exposure cases.

What are the Signs and Symptoms of Delta-8 THC Poisoning?

Even though Delta-8 is marketed as having less of a high than regular cannabis, products often contain large doses which can cause similar effects to cannabis overdose. Similar to cannabis, children are more likely to experience severe toxicity from delta-8 THC poisoning. Symptoms include:

  • Drowsiness
  • Vomiting
  • Confusion/hallucinations
  • Uncoordinated movements, difficulty walking

Severe toxicity has been associated with changes in heart rate, low blood pressure, difficulty breathing, and coma.

  • Don’t purchase edible delta-8 THC products that look like other common branded food products your child may be used to eating or drinking.
  • Choose products packaged in child resistant containers.
  • Store products up, away and out of reach when not in use. Consider keeping them in a medication lock-box or locking cabinet.


Important notes about Poison Center data

America's Poison Centers maintains the National Poison Data System (NPDS), the national database of information logged by the country’s Regional Poison Centers serving all 50 United States, Puerto Rico, the District of Columbia, and territories. Case records in this database are from self-reported calls: they reflect only information provided when the public or healthcare professionals report an actual or potential exposure to a substance, request information, or request educational materials. As such:
  • America's Poison Centers is not able to completely verify the accuracy of every report made to member centers.
  • Additional exposures may go unreported to Poison Centers and data referenced from the association should not be construed to represent the complete incidence of national exposures to any substance(s).
  • Poison Center call volume about any given substance is influenced by the public’s awareness of the hazard or even the Poison Help line itself, which are heavily influenced by both social and traditional media coverage.
  • Poison data are considered preliminary and are subject to change until the dataset for a given year has been locked.
  • America's Poison Centers is continuously working to update the NPDS substance coding taxonomy to better serve the needs of America's Poison Centers' members and surveillance partners. As a result, substances may be reclassified within NPDS’ coding hierarchy, and case counts may change. This is particularly true for novel or emerging substances.

The term “exposure” means someone has had contact with the substance in some way; for example, ingested, inhaled, or absorbed a substance by the skin or eyes, etc. Exposures do not necessarily represent poisonings or overdoses.
