Inhaling heated tobacco vapor through e-cigarettes increases chances of asthma and chronic obstructive pulmonary disease (COPD), conditions long shown to be caused by smoking traditional, combustible cigarettes.
The research data, published in the American Journal of Preventive Medicine, also suggest chances of developing COPD may be around six times greater among people who vape as well as smoke tobacco regularly, compared with those who don't use any tobacco products.
