Vaping has quickly grown into a popular alternative to smoking, but uncertainty remains around its long-term impact on lung health. As vapes deliver nicotine, THC or CBD through an inhaled aerosol, questions naturally arise on how this affects the delicate respiratory system. This comprehensive guide examines the latest evidence on what vaping does to your lungs based on scientific data rather than myths.
Vaping’s Mechanism of Absorption
Like an asthma inhaler delivering medicine, vapes work by turning liquid into an aerosol that is inhaled into the lungs. Key ingredients like nicotine, THC or CBD in the vape juice, oil or herbs are rapidly absorbed into the bloodstream once the vapor enters the lungs.
This differs from ingestible forms that must pass through the digestive system. It also contrasts with skin patches that slowly diffuse ingredients through layers of dermis. Vaping provides quick delivery of active compounds directly to the lungs, blood and brain to produce effects.
The speedy absorption and lack of harsh smoke makes vaping an attractive alternative to combustible cigarettes for many users. However, placing any foreign substance into the lungs can potentially provoke damage or disease over time. Understanding exactly how vaping impacts respiratory health helps inform personal usage decisions.
Short-Term Effects of Vaping
The immediate effects of vaping depend largely on which substance the vape is delivering:
- Nicotine – Typical short-term effects include relaxation, mood lift, increased heart rate and lightheadedness.
- THC – Cannabis vapes induce common sensations like euphoria, sedation, pain relief and slowed perception of time.
- CBD – CBD vapes provide alertness, calmness and relief from inflammation without psychoactive properties.
While each substance produces distinct effects, all vaping presents possible lung risks ranging from coughing to lung inflammation. More research is needed to quantify damage potential and mechanisms from long-term use.
Analyzing the Popcorn Lung Controversy
Popcorn lung, or bronchiolitis obliterans, involves lung scarring from inhaling the chemical diacetyl. The condition was first observed in microwave popcorn factory workers constantly breathing diacetyl vapors.
Anti-vaping advocates quickly claimed e-juices also contain diacetyl and cause popcorn lung despite zero cases attributed to vaping thus far. However, a mistaken connection was made.
Major e-juice makers immediately stopped using diacetyl once inhalation risks emerged. No reputable companies currently include diacetyl or the related chemical acetyl propionyl. While diacetyl may exist in some black market products, quality nicotine e-juices do not contain this hazardous ingredient.
Cigarettes vs. Vapes: Contrasting Lung Damage
Cigarettes wreak havoc on nearly every bodily system, but especially the lungs. The over 7,000 chemicals created during combustion directly damage lung tissue, airways and alveoli. This leads to emphysema, asthma, COPD and lung cancer among a litany of other respiratory diseases.
Conversely, vapes do not burn material and create smoke. The vapor consists primarily of nicotine, flavorings and vegetable glycerin and propylene glycol carrier bases. While long-term data is limited, evidence clearly shows vaping poses dramatically lower threats to the lungs than cigarette smoking.
However, risks still exist. Any oil or solid particles in vape juice, THC oil or dry herb can provoke inflammation when inhaled regularly at high temperatures. More research must conclusively determine long-term effects, but vaping appears far less damaging than smoking based on current science.
CBD Vaping Considerations
Vaping is a popular delivery method for CBD, the non-psychoactive cannabis derivative widely used for its therapeutic qualities. Inhaling CBD vape juice or oil allows rapid absorption and quick relief versus edibles or tinctures.
But despite CBD’s perceived safety advantages over THC, the lung risks of any vaping remain. No long-term studies exist on CBD vaping, but inhaling hot vapors could potentially lead to chronic cough, excessive mucus or lung irritation over time.
Overall, CBD vaping appears far safer than smoking, yet likely carries more respiratory risks than alternative delivery methods. Those seeking fast-acting effects must weigh benefits against potential lung and throat irritation. Additional science is required to quantify these tradeoffs.
Warning Signs of Vaping-Related Lung Illness
A mysterious vaping lung disease dubbed EVALI caused 60 deaths in 2019. Patients exhibited symptoms including:
- Shortness of breath
- Persistent cough
- Chest pain
- Fever
But a key detail often omitted in media reporting is EVALI’s link to illicit THC vapes containing vitamin E oil as a thickening additive. Nicotine vaping was not implicated in any EVALI cases. Still, discontinuing vaping and seeking medical attention for any of the above symptoms is advisable.
Clearing Up Vaping Misconceptions
Many ballistic anti-vaping articles claim vape juice contains formaldehyde, diacetyl, acetone and other dangerous chemicals. However, these substances would be immediately detectable due to their noxious odors. No reputable e-juice maker utilizes such components.
Likewise, vaping critics allege nicotine e-liquids caused EVALI based on THC vape associations. In fact, vitamin E acetate and contaminants appear only in black market THC vapes, not quality controlled nicotine products. Such false conflations wrongly malign vaping.
The Bottom Line on Vaping and Lungs
Credible scientific evidence substantiates vaping’s comparative safety advantage over traditional smoking in lung health. But risks from direct inhalation of oils, nicotine and other chemicals likely exist to some degree based on preliminary data.
Prudent vaping habits avoiding chronic heavy use and black market products greatly mitigates potential harms. Still, the long-term effects of vaping require additional rigorous study to draw definitive conclusions.
In summary, vaping affects the lungs far less severely than smoking, yet likely poses more risks than other nicotine intake methods. Those seeking to quit cigarettes should strongly consider vaping combined with smoking cessation support. But non-smokers are wisely advised to avoid vaping entirely.
