Ngokutsho kophononongo olutsha ngu Iziko elitsha loMhlaza laseRoswell Park ipapashwe kwi Uphando lweNicotine kunye noTuba, ngokusebenzisa i-e-cigarette endaweni yecuba, abatshayayo baya kuba namanqanaba eempawu zeemveliso ezinetyhefu ezifana nezo zibonwa kwiintshayi eziyeka ukutshaya.
OKUNGATSHAYI OKANYE UKUVUKA: IZIPHUMO EZIFANAYO KWIMPILO?
Olu phononongo luqhutywe yi UNjingalwazi M. Goniewicz ilinganisa i-metabolites ezisixhenxe kunye ne-17 biomarkers yokuvezwa kwi-carcinogenic okanye i-agent eyityhefu kumchamo wabantu abamalunga namashumi amabini amadala abatshayayo ababeqalile. kwi-vaping iiveki ezimbini ngo-2011.
Uthi " Ngokolwazi lwethu, olu phononongo kunye nabatshayayo lolokuqala ukubonisa ukuba ukutshintshwa kwecuba kunye necuba ze-elektroniki kunokunciphisa ukuvezwa kwezinto ezininzi eziyityhefu kunye ne-carcinogenic ezikhoyo kwicuba. »
Kolu phando luqhutywe phakathi NgoMatshi nangoJuni 2011, I-20 yabantu abadala abatshayayo abasempilweni babonelelwe nge-e-cigarettes kunye ne-20 cartridges ye-e-liquid enencasa yecuba. Abathathi-nxaxheba kuphononongo baye batshaya imidiza yesintu i-avareji yeminyaka eli-12, kwaye i-95% yabo yathi bazimisele ukuyiyeka. Bonke abathathi-nxaxheba bacelwa ukuba batshintshe i-cigarettes yabo eqhelekileyo kunye ne-e-cigarettes ezimbini ezinikezelwayo.
« Kwi-12 kwezili-17 zeempawu zebhayoloji ezilinganisiweyo, bekukho ukwehla okubonakalayo kokuchanabeka kwityhefu xa abathabathi-nxaxheba betshintsha ukusuka kwicuba eliqhelekileyo ukuya kwivaphu. Ukwehla kwezinga le tyhefu kwakufana nokuhla okubonwa kwiintshayi xa ziyeka ukutshaya yachaza ingxelo yeZiko kumaphephandaba. Ngaphandle koku abamakishi be-nicotine metabolites bahlala bengatshintshi kuninzi lwabathathi-nxaxheba.
« Amanqanaba e-nicotine epheleleyo kunye ne-polycyclic aromatics hydrocarbon metabolites awazange atshintshe emva kokutshintsha kwicuba ukuya kwi-e-cigarettes. Zonke ezinye ii-biomarkers zehle kakhulu emva kweveki ye-1 ye-vaping (p <.05). Emva kweveki ye-1, ipesenti enkulu yokunciphisa amanqanaba e-biomarker yabonwa kwi-1,3-butadiene metabolites, benzene kunye ne-acrylonitrile. Iyonke i-NNAL, i-metabolite ye-NNK, iyancipha ngo-57% kunye ne-64% emva kwe-1 kunye neeveki ze-2, ngelixa amanqanaba e-3-hydroxyfluorene ancipha ngo-46% ngeveki ye-1, kunye ne-34% ngeveki ye-2. ".
galela UNeal Benowitz, Unjingalwazi kwiYunivesithi yaseCalifornia, eSan Francisco kunye nombhali-mbhali wesifundo " Iziphumo zibonisa ukuba ukusetyenziswa kwe-e-cigarettes kunokunciphisa ngokufanelekileyo 
ukuba sesichengeni kwizinto eziyityhefu kunye ne-carcinogenic kubantu abatshayayo abatshintshela ngokupheleleyo kwi-vaping».
Ngokutsho kwe UNjingalwazi M. Goniewicz « Isiphakamiso esiphambili sophononongo sijolise kubantu abatshayayo kwaye ngakumbi abo baye bazama ukuyeka amaxesha amaninzi kwaye abazange baphumelele.". "Siyazi ukuba eyona ndlela yokunciphisa umhlaza kukuyeka ukutshaya, kodwa siyayazi kuphando lwethu ukuba inzima kangakanani le nto kwaye ngokucacileyo sicinga ngeendlela ezintsha. »
Uphando olongezelelweyo ngokuqinisekileyo luya kufuneka ukuvavanya ukuvezwa kweentshayi zevape.
