Vaping Illness Update: Stop Using THC Vaping Products

FDA strengthens warning to public to stop using THC-containing vaping products and any vaping products obtained off the street.

Audience:

Purpose:

In its continued efforts to protect the public, the U.S. Food and Drug Administration (FDA) is strengthening its warning to consumers to stop using vaping products containing THC amid more than 1,000 reports of lung injuries—including some resulting in deaths—following the use of vaping products. The FDA is working closely with the U.S. Centers for Disease Control and Prevention (CDC), as well as state and local public health partners to investigate these illnesses as quickly as possible.

While the work by federal and state health officials to identify more information about the products used, where they were obtained, and what substances they contain is ongoing, the FDA is providing members of the public with additional information to help protect themselves.

Problem and Scope:

A majority of the samples tested by the states or by the FDA related to this investigation have been identified as vaping products containing THC. Through this investigation, we have also found most of the patients impacted by these illnesses reported using THC-containing products, suggesting THC vaping products play a role in the outbreak.

Recommendations for the Public:

FDA Actions:

More information is needed to better understand whether there is a relationship between any specific products or substances and the reported illnesses. To help gather and analyze as much information as possible, the FDA is working closely with federal and state partners to identify the products or substances that may be causing the illnesses.

The FDA’s Forensic Chemistry Center is using state-of-the-art technology to analyze hundreds of samples submitted by a number of states for the presence of a broad range of chemicals, including nicotine, THC, other cannabinoids, and opioids along with cutting agents/diluents and other additives, pesticides, poisons, heavy metals and toxins.

No one substance has been identified in all of the samples tested. Importantly, identifying any compounds that are present in the samples will be one piece of the puzzle but will not necessarily answer questions about what is causing these illnesses.

Federal and state partners are following any potential leads. The FDA is committed to taking appropriate actions as the facts emerge and keeping the public informed as we have more information to share.

How to Report a Problem:

CDC and the FDA encourage the public to provide detailed information related to any unexpected tobacco- or e-cigarette-related health or product issues to the FDA via the online Safety Reporting Portal.
