Nyuka icuba ngonaphakade ekhuselekileyo?

Icuba - yeyona imveliso elisemthethweni kuphela xa athe asetyenziswa ngokomyalelo ebulala abantu. Ngoko ke ndiyacinga nje kuphela abo basebenza kukhathalelo lwempilo. Kuba amashumi eminyaka, ihlabathi lwezenzululwazi wafumana ubungqina obubhaliweyo zokwenzakalisa umsi wecuba. Siyazi ukuba imidiza ezibangela ngaphezu kokuba iintlobo kweshumi somhlaza, iingxaki intliziyo, ukufa kwamalungu omzimba, isifo yokuphefumla kunye nezinye izifo. Kutheni nangoku ngokusemthethweni zivaliwe ukutshaya? Ngaba zonke ezi siyibeka sinokuze sipheliswe kwaye ingaba izazinzulu uya kunyuka nge iisigarethi ekhuselekileyo?

carcinogens icuba kuyingozi kakhulu

Kwelinye icala, kukho abantu abakuthandayo ukutshaya, kwelinye - iqela lonke zizifo ezahlukahlukeneyo yingozi. Ngokutsho umqeshwa University of Minnesota Stephen Hecht, akukho zinto zifuneka kuqala ukuze yokuba kwixa elizayo, izazinzulu ziya ceba indlela ekhuselekileyo ukutshaya. Ingcali osebenza kwiziko Oncology uhlola nefuthe emzimbeni wakhe ukuba carcinogens icuba. Enyanisweni, umsi wecuba - cocktail entsonkothileyo ukuba iqulathe amacandelo amawaka amane. Ngenxa yokuba zonke ezi khemikhali yaye khompawundi nobudlova carcinogens ubuncinane 70 baziwa. Uluntu uyatshaya kumakhulu amaninzi eminyaka. Noko ke, kude kube ngoku akukho namnye owasungula umdiza ezinomthamo kuyehla iimveliso eziyingozi.

Kwisiqingatha senkulungwane namashishini athengisa icuba kukuqwalasela umba wayengavumi

Enyanisweni, ishishini icuba lisebenza nzima ukwenza i yecuba ekhuselekileyo kangangeminyaka engama-50. Nangona izindululo impikiswano ngohlobo iinketho ukukhanya, ngoku icacile: akukho zinto zifuneka kuqala ukuze nhlanganiso. Kubonakala ekhuselekileyo ukhetho ukutshaya efuna zixingile. On amalinge ukudala umdiza ingenangozi wathi intatheli Will Storr. Impazamo iphambili umenzi kugxininiswa kwiindlela ukwenza icebo lokucoca ekhuselekileyo. Ngelishwa, oku akunakwenzeka, kuba akukho inyathelo ekwenziweni kweziveliso zecuba ayikwazi ukugcina imveliso evela carcinogens, ekuqaleni eziqulathwe kule amagqabi. Nkqu izama ukusebenzisa njenge lokucoca into enzima afana asbestos, ubunzima ukusilela epheleleyo. Xa itshiswa icuba ekugqibeleni kuba eshiywe ngayo sulphur emlonyeni wakho zivutha iiplastiki kunye namalahle.

Angemi carcinogens kumagqabi icuba

Abanye into enzima afumaneka icuba amagqabi ngexesha lokuvuna. Okumangalisayo kukuba, izityalo ukufunxa zonke izinto eziyingozi, isinyithi kunye metalloids equlethwe lomhlaba, amanzi kunye nomoya. Icuba zidla iarseniki kunye kwimigqomo nezichumiso. Namagqabi nezityalo kweenwele ezincangathi leyo yaqokelelwa amasuntswana emoyeni lweziqalelo radioactive, ezifana ಪೇನ್ ipheyini-210.

ingqalelo kwandisa kwezi zigaba zilandelayo

Ngokubhekele phaya, xa iyoma amagqabi icuba, efumaneka izinto zabo imichiza isakhiwo zitshintshele ibe iikhompawundi ezithile - nitrosamines. Ke ngoko, xa otshayayo izibane icuba kwaye asibeke kwi emlonyeni, evuthayo icuba ezalise carbon monoxide, hydrogen benqanda kwaye yonke cocktail carcinogens, kubandakanywa - hydrocarbon polycyclic enuka kamnandi. Kwakhona emsini wecuba kukho izinto ezililize formaldehyde kunye benzene. Ngoko ke, lo gama umntu etshaya umdiza, imiphunga ezele qhu kweekhemikhali eziyingozi.

iimpembelelo indlela nto

Ayiyomfihlo ukuba ezinye carcinogens zoqhagamshelwano zidweliswe ezifumaneka ekutyeni. Noko ke, baye unyango ubushushu xa upheka yaye ibile kwisiqwenga zesisu. Kwaye kuphela ngoko ke amasalela iikhemikhali eziyingozi egazini. Ixhwele kwakhona iyavuleka icuba engcolisa ngqo umzimba wakho.

Kutheni izihluzi icuba musa ukusebenza?

Amanye amanyathelo ngokwahlukileyo ngokumandla ukunciphisa isixa carcinogens emsini. Umzekelo, izihluzi carbon ukuba ufunxe izinto ezililize. Kodwa akukho namnye amanyathelo ecetywayo akanako kuchaphazela uluhlu iphela iikhompawundi ezinobungozi.

gum nicotine

Asizange ndingathethi lizwi malunga inicotine, njengoko ayibubo umhlaza. Ingxaki kukuba gum intshongo ayiyekeki wokutshaya. Ngaphezu koko, ukwandisa izinga intliziyo, constrict imithambo yegazi kuze kuphakanyiswe amanqanaba cholesterol. Enyanisweni, inicotine yenza umntu ikhoboka kwaye yenza imihla Tsalani zonke iikhompawundi eziyingozi, nto leyo nathi ngazo ngaphambili.

Ingaba zikhona iindlela ezikhuselekileyo?

Ukuba umsi wecuba iqulethe carcinogens kakhulu, kutheni ungezi ukuhlafuna owanyayo okanye isnuff ukhetho? Akukho namnye iindlela okudalwe ngoku kuwukhulula abantu izinto ezinzima ekuqaleni eziqulathwe amagqabi icuba. Le Ngaphandle kuphela luthathwe Snus, lawula ngopfu kwimarike Swedish. Ngokutsho kweengcali, i Scandinavians kufuneka amazinga aphantsi umhlaza wemiphunga xa kuthelekiswa namazwe apho ukutshaya yemveli kwenziwa.

imidiza Electronic theory zisekhona ikhuseleke ngaphezu Snus. Noko ke, akukho bani waziyo ukuba otshayayo uyalinandipha nezingcoliso ngexesha iphefumlelwe. Yinto eyaziwayo ukuba imveliso ye e-icuba akulawulwa, nto leyo ethetha ukuba le ndlela akana- kuthenjwa. Kubonakala ukuba uluntu ngeke ingxoxo engunaphakade ikrakra.
