A number of other health effects are also worrisome: The recent tragic and alarming cases of severe lung disease are clearly cause for concern. For example, are lung problems more common among vapers who already have breathing problems (such as asthma) or who use marijuana? Is it more common among younger individuals? Does use of e-cigarettes cause the lung disease? Or is an added substance (such as marijuana) or another contaminant the culprit? Since the FDA does not actively regulate e-cigarettes, it’s particularly difficult to get answers. It’s not clear how often vaping might lead to lung trouble or who is at highest risk. What we don’t know about vaping and lung disease

The FDA, CDC, and state health officials are investigating these cases to determine the specific cause(s) and how to prevent and treat them.

The lung disease has not been linked to a specific brand or flavor of e-cigarette.

Typically, symptoms have started gradually, with shortness of breath and/or chest pain before more severe breathing difficulty led to hospital admission.

Possibilities include chemical irritation, or allergic or immune reactions to various chemicals or other substances in the inhaled vapors.

Experts aren’t sure if vaping actually caused these lung problems, but believe the most likely culprit is a contaminant, not an infectious agent.

Most cases were among teens and young adults.

Nearly 200 e-cigarette users have developed severe lung disease in 22 states (and the numbers keep rising - a Washington Post story put the number at 354).

You may have seen news reports of lung problems, including two deaths - one in Illinois and another in Oregon- linked to vaping. And while that fact is prominently displayed in advertising, we know from experience with regular cigarettes that warnings don’t always work! Recent reports link vaping to lung disease These devices heat up various flavorings, nicotine, marijuana, or other potentially harmful substances. And nearly seven million adults 18 or older use e-cigarettes, according to a 2017 survey by the CDC.Į-cigarettes use a battery-powered device that heats a liquid to form vapors - or, more accurately, aerosol - that the user can inhale (thus 'vaping'). Certainly, age restrictions - it’s illegal to sell e-cigarettes to anyone under 21 (18 or 19 in some states) - aren’t preventing use among teens and young adults.

An estimated 2.1 million middle school and high school students reported using e-cigarettes in 2017 that number jumped to 3.6 million in 2018. According to a recent study, about 37% of high school seniors reported vaping in 2018, up from 28% the year before.

The rising popularity of vaping has been dramatic, especially among teenagers.
