In the study, 22 healthy men and women smoked e-cigarettes with and without nicotine on two separate occasions.
Analyses from blood samples show that certain inflammatory markers of damage increase after only a few puffs. Those who smoke e-cigarettes take on average between 150 and 200 puffs per day.
We were surprised that we could see these effects on inflammatory activity and vascular damage as soon as after thirty puffs, says research leader Fariborz Mobarrez to SVT.
So far, researchers do not know enough about the long-term effects, but already now Mobarrez states that e-cigarettes are not as "harmless as one thought" and that they give "the same negative effects as smoking".
When the body is constantly exposed to nicotine's disruptions, it risks recalibrating its normal balance, which in turn can pave the way for everything from rheumatic disease to cardiovascular disease.
