In recent years, e-cigarettes, or vaporizers, have been increasingly marketed as a safe alternative to smoking. E-cigarettes are classified as electronic nicotine delivery systems and operate through the use of a heating element that heats fluid contained in the device and creates a vapor which is then inhaled by the user. While research has not yet been able to conclude for certain if using e-cigarettes is safer than smoking tobacco, there may be reason to believe that they pose a risk to public health.
For those using e-cigarettes as an alternative to smoking, or in an effort to quit smoking all together, there is some information that should be considered. While the nicotine-containing fluid that is converted to vapor contains far fewer toxic ingredients than tobacco products, e-cigarettes are not yet regulated by the FDA and much about the devices remain unknown. There may be less overall toxins in e-cigarette vapor, but the concentrations of certain dangerous compounds that users can be exposed to have caused concern among scientists. Just recently, a study showed that levels of formaldehyde, a known carcinogen generated by vaporizers at a high voltage greatly exceeds that contained in traditional cigarettes.
Beyond the chemicals produced through the use of e-cigarettes, the vapor particles they produce are similar to the size found in traditional cigarette smoke. This allows them to reach small, deep airways much like cigarette smoke. These particles could also pose a risk to those exposed to secondhand vapor. Exposure to secondhand vapor is also more likely than tobacco smoke as there is currently little regulation of e-cigarette use, allowing many to use them indoors where traditional smoking bans exist. One study has shown that among other nanoparticles, a high concentration of heavy metals has been observed in e-cigarette vapor. The same study suggested these concentrations were derived from the heating element that consists of nickel-chromium wire, coated in silver, and soldered with tin.
Another possible risk associated with e-cigarettes concerns the nicotine refill cartridges, which can be unintentionally consumed, particularly by children. The number of these unintentional consumption events has been increasing in recent years according to a study by tobacco control. The amount of nicotine in some refill solutions could potentially be lethal to children.
While e-cigarettes could potentially be safer than traditional cigarettes, they certainly deserve regulatory action in order to ensure that human health is protected. For those that are looking for a safe method to quit smoking, e-cigarettes should be avoided until definitive research concludes they are safe. Until that time, it is probably wise to utilize other methods that are FDA-approved.
								
In July of 2013, an explosion occurred at the WTI/Heritage Thermal Services (HTS) hazardous waste incinerator in East Liverpool, OH. Incinerator ash that had built up on the inside of the incinerator stack suddenly fell off causing a huge cloud of dust contaminated with heavy metals and other toxic substances to be released from the stack. An estimated 800 to 900 pounds of ash were released into the surrounding community. The plant manager advised residents to wash fruits and vegetables from their gardens and to replace food and water for pets and farm animals. Save Our County, a local group that has been fighting to shut down the incinerator for more than 20 years and other local residents were quite alarmed by what happened and asked whether this latest accident further put their health at risk.

s out its plan for continuing to address environmental justice in the context of the agency’s work. EPA is hoping to build on its EJ 2014 Action Agenda and expand that work through commitments that will continue over the next five years. EPA is seeking input on the draft EJ 2020 Action Agenda framework. The public comment period runs from April 15 to June 15. The agency is planning to conduct informational and dialogue sessions during this comment period and is encouraging the public to submit written comments. For more details, see:
