Researchers to study long-term effects of vejpning

Major study on how e-cigarettes affect the lungs - in non-smokers

Researchers in Italy and the US are preparing a study to see how vejpning affects the lungs of non-smokers. The researchers are looking for hundreds of participants from around the world. The study will last six years.

“Nästan alla studier som tittar på hälsoeffekter av e-cigaretter bygger på användare som är tidigare rökare. Det har varit omöjligt att skilja små effekter från  vejpningen från långtidseffekter orsakade av rökningen. I den här studien testar vi hypotesen att e-cigaretter i sig inte orsakar mätbara hälsoeffekter” the researchers write in an appeal.

Long-term effects of e-cigarettes

Riccardo Polosa, an Italian doctor and professor, will lead the study. Polosa has previously published results of a similar study, limited to a small number of non-smokers in Italy who use e-cigarettes. The results showed that people who had not previously smoked cigarettes regularly did not show signs of lung damage, even after five years of 1TP8 use.

“Samtidigt antyder vissa labbtester på möss att ångan från e-cigaretter har potential att skada lungorna. Men det är ytterst oklart hur detta fungerar under verkliga förhållanden.” skriver forskarna.

Not harmless - but less toxic

The study is an important contribution to research on e-cigarettes and their potential health effects, say the researchers. 

“Vi vet att ångan inte är helt harmlös, men att den innehåller betydligt färre koncentrationer av gifter än cigarettrök. Den här studien hjälper oss att förstå de absoluta långtidsriskerna med e-cigaretter. Om det finns några.” skriver forskarna bakom studien.

Volunteers are currently being recruited from all over the world. In total, 16 countries are represented (not Sweden, yet). But more can be added. Registration for the study can be done via Veritas website
