Following a multi-year planning and development process, we are excited to replace our current website on September 26 with a new design that will serve as a digital gateway to a wide variety of public services and information.


Vaping devices11/21/19 Update: CDC has identified vitamin E acetate as a chemical of concern among people with e-cigarette or vaping product use associated lung injury (EVALI). Recent CDC laboratory testing of fluid samples collected from the lungs from 29 patients with EVALI submitted to CDC from 10 states found vitamin E acetate in all of the samples. Vitamin E acetate is used as an additive, most notably as a thickening agent in THC-containing e-cigarette or vaping products.

CDC recommends that people should not use THC-containing e-cigarette or vaping products, particularly from informal sources like friends, or family, or in-person or online dealers. While this investigation is ongoing, vitamin E acetate should not be added to e-cigarette or vaping products.

In addition, people should not add any substance to e-cigarette or vaping products that are not intended by the manufacturer, including products purchased through retail establishments. CDC will continue to update guidance as appropriate as new data become available from this outbreak investigation.

10/17/19 Update: The Oregon Court of Appeals has granted a temporary stay of Oregon Health Authority’s temporary rules banning flavored vaping products.

10/11/19 Update: OHA, OLCC file rules banning flavored vaping sales, including online. Read the press release here for more details.

9/26/19 Update: The Oregon Health Authority has issued a public health warning urging people to stop vaping immediately, after another death in Oregon. Read the press release here for more details.

As of November 20, 2019, 47 deaths — including two in Oregon — and 2,290 cases of lung illness have been associated with the use of vape devices (such as JUUL, Suorin and SMOK) and e-cigarettes across the country.

Patients have reported symptoms such as cough, shortness of breath, chest pain, nausea, vomiting, diarrhea, fatigue, fever and abdominal pain. Some patients have reported that symptoms developed over a few days, while others reported that it took several weeks. So far, investigators have not identified a specific vape product or substance that is causing the lung illness. 

We urge people not to vape or use any type of e-cigarettes until health officials understand the cause of the illness.


Parents, please talk to your kids about the dangers of vaping. You can find tips on CDC’s website: E-Cigarettes: Talk to Youth About the Risks. Despite all our best efforts, some youth are still going to vape.

What parents should watch out for

  • Symptoms: Coughing, trouble breathing, chest pain, nausea, vomiting, abdominal pain or fever after vaping could be serious. Seek medical attention right away.
  • Equipment: You may find devices that look like flash drives, pods that contain e-juice, which is the flavored fluid that is used inside vaping devices, e-juice bottles or product packaging.
  • Purchases: Online, packages in the mail, store purchases.
  • Scent: While the odor from vaping is faint, you may catch a whiff of a flavoring where there appears to be no other source (e.g., cotton candy, berry, mint, crème brûlée.).
  • Increased thirst or nose bleeds: Some of the chemicals used in e-juices dry out the mouth and nasal passages. As a result, some kids drink more liquids or seem more prone to nose bleeds.
  • Decreased caffeine use: Some teens and young adults who vape develop a sensitivity to caffeine.
  • Vaping lingo: You may see lingo in text messages such as “atty” for an atomizer, “VG” for vegetable glycerin found in e-juice, or “sauce” referring to e-juice. 
  • Social media: Pictures or videos on Instagram, YouTube or Twitter accounts.
  • Appearance and/or behavior changes: Trust your instincts and be aware of any unusual changes.

Again, because we don’t know yet which types of e-cigarettes or vaping device are causing this serious illness, the safest thing is to not vape at all.

This advice goes for adults as well. If you choose to vape, never buy vape products off the street or from unofficial online vendors. Do not modify a vape device or add or alter the substances provided by the manufacturer.

For more information on the outbreak and recommendations, please see the FDA’s consumer update on vaping illnesses.

If you or someone you know would like to quit using tobacco or nicotine products, visit, call 1-800-QUIT-NOW, or see a health care provider about FDA-approved nicotine replacement and cessation options, such as skin patches, gum, lozenges, inhalers and prescription medications.
