Vaping and the effect on the lungs
Inhaling vapor is less dangerous than smoking, that is not disputed. The question is whether vapors can be harmful to the lungs. Unfortunately, e-cigarettes do not exist long enough to give a definitive answer to this. Small-scale studies have been conducted in which the effects of vapors have been tested.
Is vaping healthier than smoking?
Dr. David Thicket is a breathing specialist, he works at the University of Birmingham, England. Although he acknowledges that vapor is less harmful than smoke, he does question the longer-term effects. Various scenarios were tested in a (very) small-scale study; smoke, vapor (with and without nicotine) and an alternative. This showed that vapor from an e-cigarette influences the cells in the lungs. This effect may not be reversible, which can lead to chronic conditions.
Chronic Obstructive Pulmonary Disease is a condition in which a chronic narrowing occurs in the lungs. There are various stages, the most serious of which is life-threatening. The question is whether long-term vapors can cause COPD. Unfortunately, too little data is available to draw firm conclusions, and large-scale tests have not yet been conducted. It cannot be excluded that fumes from e-liquid can cause damage to the lungs.
Vapors may not be labeled as a healthy alternative to smoking, but it does seem to be a less unhealthy alternative for the time being. In particular, the absence of the carcinogenic soot and tar substances is already a step in the right direction. We will keep a close eye on further developments and look forward to clear conclusions with interest.
