Ua helu ʻia ka honi ʻana i nā paka uila he uahi lua?

ʻO ka noiʻi ʻana i nā nitrosamines ʻaʻole kānalua ka ʻāpana koʻikoʻi o nā haʻawina he nui.Wahi a ka World Health Organization papa inoa o nā carcinogens, ʻo nitrosamines ka carcinogen mua loa.Loaʻa i ka uahi paka ka nui o nā nitrosamines pili i ka paka (TSNA), e like me NNK, NNN, NAB, NAT… I waena o lākou, ua ʻike ʻia ʻo NNK a me NNN e ka WHO he mau kumu kumu nui o ka maʻi kanesa, ʻo ia ka carcinogens nui. o ka paka a me ka pilikia o ka uahi lua.ʻO ka "hewa".

Loaʻa i ka uahi paka uila nā nitrosamines pili i ka paka?I ka pane ʻana i kēia pilikia, ma 2014, koho ʻo Kauka Goniewicz i nā huahana e-cigarette kiʻekiʻe 12 ma ka mākeke i ka manawa no ka ʻike ʻana i ka uahi.Hōʻike nā hualoaʻa hoʻokolohua ʻo ka uahi o nā huahana cigareti uila (ʻo ka hapa nui o ke kolu o ka hanauna o ka uahi paka uila) i loaʻa i nā nitrosamines.

Pono e hoʻomaopopo ʻia ʻoi aku ka haʻahaʻa o ka ʻike o ka nitrosamines i ka uahi e-cigarette ma mua o ka uahi paka.Hōʻike nā ʻikepili i ka ʻike NNN i ka uahi e-cigarette he 1/380 wale nō o ka NNN maʻiʻo o ka uahi paka, a ʻo ka maʻiʻo NNK he 1/40 wale nō o ka NNK maʻiʻo o ka uahi paka."Haʻi mai kēia haʻawina iā mākou inā e hoʻololi ka poʻe puhi paka i ka e-cigarettes, hiki iā lākou ke hōʻemi i ka lawe ʻana i nā mea ʻino pili i ka paka."Ua kākau ʻo Kauka Goniewicz ma ka pepa.

I Iulai 2020, ua hoʻopuka ka US Centers for Disease Control and Prevention i kahi palapala e hōʻike ana he haʻahaʻa loa ke kiʻekiʻe o ka nitrosamine metabolite NNAL i loko o ka mimi o nā mea hoʻohana e-cigarette, e like me ke kiʻekiʻe o ka NNAL i ka mimi o nā mea puhi ʻole. .ʻAʻole wale kēia e hōʻoia i ka hopena hōʻemi nui o ka e-cigarettes ma ke kumu o ka noiʻi ʻana a Kauka Goniewicz, akā hōʻike pū ʻia hoʻi ʻaʻole i loaʻa i nā huahana e-cigarette nui ka pilikia o ka uahi lua mai ka paka.

Ua mau ke aʻo ʻana no 7 mau makahiki a hoʻomaka e hōʻiliʻili i ka ʻikepili epidemiological e pili ana i ka hoʻohana ʻana i ka paka i ka makahiki 2013, me nā ʻano hoʻohana, nā ʻano, nā maʻamau, a me nā hopena olakino.ʻO ka NNAL kahi metabolite i hana ʻia e ke kino o ke kanaka e hana ana i nā nitrosamines.Hoʻomoʻa ka poʻe i ka nitrosamines ma o ka hoʻohana ʻana i nā huahana paka a i ʻole ka uahi lua, a laila hoʻopau i ka metabolite NNAL ma o ka mimi.

Hōʻike nā hopena o ke aʻo ʻana ʻo ka awelika o ka NNAL i loko o ka mimi o nā mea puhi paka he 285.4 ng / g creatinine, a ʻo ka awelika o ka NNAL i loko o ka mimi o nā mea hoʻohana e-cigarette he 6.3 ng / g creatinine, ʻo ia hoʻi, ka ʻike. o NNAL i loko o ka mimi o nā mea hoʻohana e-cigarette he 2.2% wale nō o ka huina.
