Txawm hais tias qhov tseeb tias kev haus luam yeeb e-luam yog suav tias tsis muaj kev phom sij, cov kws tshawb fawb tsis tau nrawm nrog cov lus pom zoo li no. Ntawm qhov tsis sib xws, lawv hais tias kev nqus pa ntawm cov pa ua rau muaj kev puas tsuaj rau lub ntsws, lwm yam hu ua "popcorn disease".

Vapers (xws li cov neeg haus luam yeeb e-luam yeeb) ua rau lawv tus kheej muaj kev pheej hmoo ntawm kev tsim tus kab mob "popcorn lung disease." Qhov kev txiav txim siab no tau ua los ntawm cov kws tshawb fawb tom qab lawv pom cov tshuaj lom neeg hauv 75% ntawm cov tshuaj tsw qab e-luam yeeb.

Diacetyl, tshuaj uas siv los ua cov roj tsw qab hloov hauv cov zaub mov, tau ua rau bronchiolitis obliterans. Tus kab mob no tau pom yav dhau los hauv cov neeg ua haujlwm ntawm lub tuam txhab paj kws.

Diacetyl ntseeg tau tias tuaj yeem noj tau, tab sis US National Occupational Safety Institute tau hais tias cov tshuaj yuav ua rau muaj kev phom sij yog tias nqus tau ntev. Diacetyl ua rau mob, caws pliav, thiab nqaim ntawm cov pa me me hauv lub ntsws, lwm yam hu ua bronchioles. Vim li ntawd, tus neeg ntawd tsis tau txais oxygen txaus. Yuav tsum tau ua sai sai los soj ntsuam kom raug raws li qhov ua tau raws li qhov uas cov khoom txaus ntshai kis tau ntawm cov luam yeeb flavorings, cov kws tshawb fawb hais tias.

"Kev lees paub txog kev phom sij ntawm kev nqus cov tshuaj tau pib nrog qhov tshwm sim ntawm cov kab mob paj kws paj kws tshaj li kaum xyoo dhau los," tus thawj coj tshawb fawb Joseph Allen, tus xibfwb ntawm Harvard Tsev Kawm Ntawv Kev Noj Qab Haus Huv. "Txawm li cas los xij, diacetyl siv ntau yam khoom qab zib - tsis tsuas yog los tsim cov ntxhiab ntawm cov paj kws kib, tab sis kuj muaj cov txiv hmab txiv ntoo, cawv thiab khoom qab zib, thiab, raws li peb tau kawm, hauv e-luam yeeb flavors uas tsw zoo li khoom qab zib."

E-luam yeeb siv cov cartridges uas xa cov tshuaj nicotine xav tau. Cov koob tshuaj no tau txais los ntawm cov neeg haus luam yeeb los ntawm kev nqus cov pa uas tsis muaj tar thiab lwm yam tshuaj carcinogenic. Cov kws tshawb fawb thiab cov thawj coj tseem tsis paub meej tias kev haus luam yeeb no puas muaj kev nyab xeeb. Nyuam qhuav pib lub xyoo no, Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv Askiv tau hais kom cov neeg haus luam yeeb hloov mus rau e-luam yeeb vim tias lawv muaj kev nyab xeeb dua li kev haus luam yeeb ib txwm muaj. Txawm li cas los xij, Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv, cov kws tshawb fawb los ntawm London Tsev Kawm Ntawv Kev Noj Qab Haus Huv thiab Tshuaj Kho Mob thiab cov neeg ua haujlwm hauv University of Liverpool tseem txhawj xeeb txog kev nyab xeeb ntawm e-luam yeeb.

Dr. Allen thiab nws cov npoj yaig tau sim 51 cov luam yeeb thiab cov kua tsw qab uas muag los ntawm cov khoom lag luam rau diacetyl, acetoin thiab 2,3-pentanedione, cov tshuaj tsw qab uas tuaj yeem ua rau muaj kev pheej hmoo rau lub ntsws ntawm cov neeg haus luam yeeb thiab cov neeg nyob ib puag ncig nws.

Txhua lub e-luam yeeb tau muab tso rau hauv lub kaw lus kaw thiab cov kwj ntawm huab cua tau dhau los ntawm nws rau yim vib nas this. Tom qab ntawd, tom qab 15-30 vib nas this, huab cua tau dhau mus, thiab tom qab ntawd dhau mus rau kev tshuaj xyuas.

Tsawg kawg yog ib qho ntawm peb cov tshuaj tau pom nyob rau hauv 47 ntawm 51 cov tshuaj tsw qab. Diacetyl tau pom hauv 39 cov qauv, acetoin hauv 46, thiab 2,3-pentanedione hauv 23.

"Vim tias feem ntau ntawm cov teeb meem nyob ib puag ncig e-kev haus luam yeeb yog nyob ib puag ncig nicotine, peb paub tias tseem muaj ntau yam peb tsis paub txog e-luam yeeb," hais tias kev tshawb fawb co-sau Dr. David Christiani, tus xibfwb ntawm ib puag ncig genetics.

Ntxiv rau qhov tseeb tias e-luam yeeb muaj ntau yam tshuaj nicotine - ib qho tshuaj alkaloid - lawv kuj muaj cov tshuaj carcinogenic xws li formaldehyde. Tsis tas li ntawd, peb cov kev tshawb fawb tau pom tias cov ntxhiab tsw hauv e-luam yeeb tuaj yeem ua rau muaj kev phom sij thiab ua rau lub ntsws puas.

Txawm hais tias txoj kev tshawb no tau ua nyob rau hauv Tebchaws Meskas, cov kws tshawb fawb Greek tau ua haujlwm zoo ib yam li xyoo tas los. Tom qab ntawd lawv pom tias diacetyl pom nyob rau hauv 70% ntawm European hom tshuaj tsw qab. Ob qho tib si Asmeskas thiab European cov kua haus luam yeeb muaj muag.
