The first time you vape could already have an impact on your body, according to a small international study. Previous research shows both tobacco and e-cigarettes increase your levels of cellular oxidative stress (COS), which can assist in the development of many diseases. Researchers tested the level of COS in a group of 32 people before and after either vaping or 'sham vaping,' puffing on a straw without nicotine. Of the 11 participants who had not previously smoked or vaped, the researchers recorded an increase in COS in those who vaped in the experiment but not in those who sham-vaped. For the participants who were regular tobacco smokers or e-cigarette users, the researchers did not record an increase in COS after one vaping session, however their baseline COS levels were higher than non-smokers.
