Cancer-Causing Chemicals in e-Cigarettes – NOT Harmless Water Vapor

e-cigarettes – NOT safe or harmless.

Electronic cigarettes (e-cigarettes) are battery-powered devices that deliver aerosolized nicotine and flavors.
While there are Zero Nicotine options delivering flavors they ARE NOT SAFE and they do deliver cancer-causing chemicals.

e-Liquid, aka eJuice, What else is being inhaled????

One brand, Candy King (looks like a juice box or candy)
Typical Ingredients
  • Alcohol
  • 70% Vegetable Glycerin
  • 30% Propylene Glycol.
  • 1% or less of Sucralose and/or Ethyl Maltol
  • Artificial or Natural Flavoring

“Ingestion of e-cigarette liquids containing nicotine can also cause acute toxicity and possibly death if the contents of refill cartridges or bottles containing nicotine are consumed.”

Vivek H. Murthy, M.D., M.B.A. U.S. Surgeon General



The advertising says, “Vivid Vanilla is deliciously sultry, inviting and lightly aromatic for a taste that’ll perfectly complement your relaxation time.”

Ingredients: nicotine (not in the 0% liquidpod), propylene glycol and vegetable glycerin, natural and artificial flavors.



Carcinogenic Delivery Systems Marketed and Packaged to Appeal to Kids and Teens

Vape Stats 2017-2018

  • 38% of high schoolers and 13% of middle schoolers have tried vaping – CDC
  • Vape vapor can cause inflammations in the mouth, eventually leading to gum disease







Source: Centers for Disease Control and Prevention 2013, 2014; unpublished data (data: NYTS 2015). Note: In 2014, modifications were made to the e-cigarette measure to enhance its accuracy, which may limit the comparability of this estimate to those collected in previous years. The dotted lines from 2013 to 2015 represent these differences. aIncludes those who responded “yes” to the following question: “Have you ever used an electronic cigarette or e-cigarette, even once or twice?”





Some vape devices look like a USB drive.


We know that’s not a new USB flash drive. That device that looks like a thumb drive is a way to get a nicotine fix. It plugs into a laptop to charge. Students carry these pocket-size vaporizers and swap out flavored nicotine juice cartridges that deliver a nicotine hit without any tobacco. We’ve heard about the kids who sit in the back of the class sneaking puffs while an unsuspecting teacher lectures. There are middle and high school bathrooms filled with vapor where kids go to vape between classes. It seems like everyone is doing it, right? ~Aisha Sultan,

DEADLY. The e-liquid vaped contains carcinogenic chemicals.

How it works: Fluids are heated in electronic cigarettes (“e-cigarettes“) creating “vaping” aerosols.
The aerosols can cause a wide range of chemicals as a result, called degradation reaction products.


Scientists have found a very harmful toxin is sometimes produced called benzene. Benzene causes cancer in humans.
Benzene has been shown to form from e-cigarette fluids containing propylene glycol, glycerol, benzoic acid, the flavor chemical benzaldehyde, and nicotine.

This study found compounds known to cause bladder cancer in the urine of e-Cig users.
Sci Rep. 2018 Jan 11;8(1):507. doi: 10.1038/s41598-017-19030-1.
This study found that e-cigarettes caused Significant oxidative DNA damage to cells (more than cigarettes).
e-Cigs are creating a potential long-term cancer risk for vapers and the general public.

31 Compounds Found – What are you inhaling?

These studies showed that aerosols generated with vaporizers contained 31 compounds, including nicotine (carcinogen), nicotyrine, formaldehyde, acetaldehyde (carcinogen), glycidol (probable carcinogen), acrolein (powerful irritant), acetol, diacetyl (carcinogen).

Heating/Vaporizing Glycerine creates glycol and acrolein.

This study found toxic metal concentrations in five, nationally popular brands of cig-a-like e-cigarettes

All of the tested metals (cadmium, chromium, lead, manganese and nickel) were found in the e-liquids analyzed

Electronic Cigarettes are Not Safe for Bystanders.


The cloud that people exhale from e-cigarettes exposes you to harmful chemicals that are not safe to breathe.



According to American Nonsmokers’ Rights Foundation,


  • Electronic smoking devices (ESDs) do not just emit “harmless water vapor.” 
  • Secondhand aerosol (incorrectly called vapor by the industry) from ESDs contains nicotine, ultrafine particles and low levels of toxins that are known to cause cancer.
  • ESD aerosol is made up of a high concentration of ultrafine particles, and the particle concentration is higher than in conventional tobacco cigarette smoke.
  • Exposure to fine and ultrafine particles may exacerbate respiratory ailments like asthma, and constrict arteries which could trigger a heart attack.
  • ESDs contain and emit propylene glycol. Short term exposure causes eye, throat, and airway irritation.  Long term inhalation exposure can result in children developing asthma.
  • Some studies show that heating propylene glycol changes its chemical composition, producing small amounts of propylene oxide, a known carcinogen.
  • FDA scientists found detectable levels of carcinogenic tobacco-specific nitrosamines in ESD aerosol.
  • Exhaled ESD aerosol contained propylene glycol, glycerol, flavorings, and nicotine, along with acetone, formaldehyde, acetaldehyde, propanal, diacetin, and triacitine.
  • Many of the elements identified in the aerosol are known to cause respiratory distress and disease.
  • Short term use of ESD has been shown to increase respiratory resistance and impair lung function, which may result in difficulty breathing.
  • Concentrations of formaldehyde are higher than concentrations of nicotine in some samples of ESD aerosol.
  • High doses of diacetyl, used to flavor buttered popcorn, have been shown to cause acute-onset bronchiolitis obliterans, a severe and irreversible obstructive lung disease when inhaled by workers exposed to particulate aerosolized flavorings containing diacetyl. Therefore, these chemicals cannot be deemed “generally recognized as safe” for inhalation.
