Kev nyab xeeb ntawm cov luam yeeb hluav taws xob pov tseg yog ib qho teeb meem kev txhawj xeeb heev. Raws li ib yam tshiab ntawm cov khoom luam yeeb, kev nyab xeeb ntawm cov luam yeeb hluav taws xob yuav tsum tau soj ntsuam los ntawm kev tshawb fawb pom. Kab lus no yuav tshawb txog kev nyab xeeb ntawm cov luam yeeb hluav taws xob pov tseg raws li cov pov thawj scientific uas twb muaj lawm.
Cov luam yeeb hauv hluav taws xob feem ntau suav hais tias yog ib qho kev nyab xeeb rau cov luam yeeb ib txwm muaj. Nws cov khoom tseem ceeb yog nicotine, propylene glycol thiab essence, uas tsim cov pa taws los ntawm atomization cua sov. Txawm li cas los xij, tseem muaj kev sib cav txog kev nyab xeeb ntawm cov luam yeeb hluav taws xob.
Ntawm qhov tod tes, qee qhov kev tshawb fawb tau pom tias e-luam yeeb tuaj yeem txo qis kev noj cov tshuaj phem rau tib neeg lub cev. Piv txwv li, ib txoj kev tshawb fawb hauv Tebchaws Meskas tau pom tias cov neeg haus luam yeeb hloov ntawm luam yeeb mus rau e-luam yeeb muaj yuav luag tib theem ntawm cov teeb meem hauv lawv cov zis thiab exhaled gases li cov neeg uas txiav luam yeeb tag. Lwm txoj kev tshawb fawb kuj qhia tau hais tias cov ntsiab lus ntawm polycyclic aromatic hydrocarbons nyob rau hauv cov pa exhaled ntawm e-luam yeeb cov neeg siv poob los ntawm 64.7% piv rau cov neeg haus luam yeeb, cov ntsiab lus ntawm acrylonitrile txo los ntawm 89%, thiab cov metabolites ntawm luam yeeb nitrosamines (TSNA), NNAL. thiab NNN, hauv cov zis txo los ntawm 64.2% thiab 74.1%, feem. Cov tshuaj no yog cov tshuaj carcinogenic tsim tom qab luam yeeb.
Ntawm qhov tod tes, tseem muaj qee qhov teeb meem hais txog kev nyab xeeb ntawm cov luam yeeb hluav taws xob. Piv txwv li, nicotine thiab lwm yam khoom tsis zoo hauv e-luam yeeb yuav muaj kev cuam tshuam tsis zoo rau kev noj qab haus huv. Tsis tas li ntawd, qee cov khoom lag luam e-luam yeeb yuav muaj teeb meem zoo, xws li kev pheej hmoo ntawm cov roj teeb tawg.
