Fumare le sigarette elettroniche? Non ne vale la pena. Troppo rischiose per il sistema cardiovascolare. Lo sostengono i ricercatori dell'Ohio State University, che hanno trovato sempre più dati sui loro effetti collaterali.
"Le e-cig contengono nicotina, particolato, metalli e aromi, non solo dell'innocuo vapore acqueo - commenta Loren Wold, coordinatrice dello studio pubblicato sulla rivista "Cardiovascular Research" -. Dagli studi sull'inquinamento atmosferico sappiamo che il particolato fine entra in circolazione e ha effetti diretti sul cuore. I dati sulle sigarette elettroniche vanno in questa direzione".
Le prove dei loro effetti dannosi sul cuore e i vasi sanguigni si vanno accumulando. La nicotina aumenta la pressione del sangue e il battito cardiaco, mentre il particolato fa indurire le arterie, con effetti sui polmoni.
"Molti studi hanno esaminato gli effetti acuti dello svapo, ma l'effetto dell'esposizione cronica non è stato analizzato", aggiunge. Inoltre gli ingredienti e il modo di rilascio non sono standardizzati.
