Ucwaningo lwakamuva olwenziwe yiNyuvesi yaseCalifornia luthole ukuthi amakhemikhali athile kugwayi we-elekthronikhi ahlobene nokulimala kwamehlo. Ucwaningo olunesihloko esithi "Inhlangano Phakathi Kokusetshenziswa Kwe-E-Cigarette kanye Nokukhubazeka Okubonakalayo e-United States" ibisebenzisa idatha eqoqwe phakathi kuka-2016 no-2018 kubantu abadala abangu-1,173,646 abaneminyaka engu-18 neminyaka engu-50.
Ukuhlaziywa kwedatha kubonise ukuthi abantu abasebenzisa i-e-cigarettes babengama-34% athanda ukuthola ukukhubazeka okubukwayo. Labo abangazange babe ne-vape babenethuba elingu-14% lokuthola ukukhubazeka kokubona. Ithimba elenza lolu cwaningo liphethe ngokuthi okutholwe kwalolu cwaningo kuwubufakazi bokuthi ezinye zezinto ezincibilikisa emikhiqizweni ekhipha umhwamuko zilimaza iso ngamakhemikhali. Bakholelwa ukuthi ama-solvents ku-e-cigarettes abangela ukucindezeleka kwe-oxidative emzimbeni wabantu abasebenzisa imikhiqizo yokuphefumula futhi balimaze imigudu yezinyembezi. Lokhu kokubili kuhlobene nokuwohloka kancane kancane kwamehlo omuntu.
Olunye ucwaningo olushicilelwe ku-Journal Nicotine and Tobacco Research olwenziwe yi-UCLA lubheke izinzuzo zokusebenzisa ugwayi we-elekthronikhi kanye nemikhiqizo yokukhipha umphunga phezu kukagwayi wendabuko. Ucwaningo luphinde lwaphenya umthelela wokudambisa ugwayi we-e-cigarette ekwehliseni izingozi zezifo zenhliziyo nemithambo yegazi. Ucwaningo lwaphetha ngokuthi i-e-cigarettes yayiphephile uma kuqhathaniswa.
Ucwaningo olwenziwe yithimba labacwaningi baseBoston University, University of Texas kanye ne-UCLA olunesihloko esithi “Izinhlangano Zokusebenzisa Ugwayi Okungenantuthu Nengozi Yezifo Zenhliziyo: Imibono Evela Ekuhloleni Kwabantu Bogwayi Nocwaningo Lwezempilo” ujule endimeni ye-e-cigarette ekunciphiseni izingozi zenhliziyo nemithambo yegazi. Ucwaningo luphinde lwasebenzisa isampula ezweni lonke elinikeze imiphumela elinganiselayo.
Ithimba labacwaningi ligxile ekuhlaziyeni idatha eqoqwe kubantu abadala abangu-4,347 kuzwelonke abanikeze amasampula egazi labo nomchamo ukuze kuhlolwe inani labantu ocwaningweni lukagwayi kanye nezeMpilo (Indlela) ngo-2013-2014. Kumasampula aqoqiwe, amasampula angama-975 kwakungabangabhemi abangakaze basebenzise noma imuphi umkhiqizo kagwayi, angama-338 asebenzisa imikhiqizo yokuphefumula kuphela kanti angu-3,034 asele abhema ugwayi kuphela.
Ucwaningo luveza ukuthi nakuba amasampula avela kubo bobabili ababhemayo nabasebenzisa ugwayi we-e-cigarette ayenamazinga afanayo e-nicotine, lawo avela kubasebenzisi be-e-cigarette ayenama-biomarker aphansi ezifo ezihlukahlukene. Umcwaningi oholayo uProfesa Mary Rezk-Hanna wathi: “Okutholakele kubonisa ukuthi naphezu kokuba nenani eliphakeme le-nicotine, abantu abasebenzisa ugwayi ongenayo intuthu kuphela babenezinga eliphansi kakhulu lokuvuvukala nezimpawu zokucindezeleka kwe-oxidative kunalabo ababhema ugwayi. Amazinga alezi zimpawu ze-biomarker phakathi kwabasebenzisi bakagwayi abangenantuthu ayefana nalawo 'abangakaze' babheme.”
