\nVaparea, adic\u0103 procesul de inhalare a aburilor creat de \u0163ig\u0103rile electronice, poate afecta vasele de s\u00e2nge, s\u0103 reduc\u0103 ritmul circula\u0163iei s\u00e2ngelui \u015fi s\u0103 creeze toxine periculoase, potrivit unui studiu recent care a ap\u0103rut \u00een publica\u0163ia Radiology.

\nPentru derularea studiului, cercet\u0103torii de la Universitatea de Medicin\u0103 Perelman din Pennsylvania au efectuat un RMN pe 31 de non-fum\u0103tori s\u0103n\u0103to\u015fi at\u00e2t \u00eenainte, c\u00e2t \u015fi dup\u0103 ce au vapat \u0163ig\u0103ri electronice, f\u0103r\u0103 nicotin\u0103. Participan\u0163ii la studiu au inhalat de 16 ori, timp de c\u00e2te trei secunde, vaporii \u0163ig\u0103rilor electronice care aveau arome de tutun \u015fi \u00eendulcitor, potrivit NBC News.<\/p>\n
\nCercet\u0103torii au descoperit c\u0103 dup\u0103 vapare, ritmul circula\u0163iei s\u00e2ngelui a sc\u0103zut \u00een artera femural\u0103 – principala arter\u0103 care \u201elivreaz\u0103\u201d s\u00e2nge spre coapse \u015fi picior. De fapt, participan\u0163ii la studiu au avut o circula\u0163ie mai proast\u0103, artere mai pu\u0163in flexibile \u015fi mai pu\u0163in oxigen \u00een s\u00e2ngele lor.\u201eRezultatele studiului nostru combat ideea c\u0103 vaparea \u0163igaretelor electronice nu este d\u0103un\u0103toare\u201d, spune Felix Wehrli, cel care a condus studiul, potrivit Wired. Mai exact, cercet\u0103torii au o observat o reducere cu 34% a dilat\u0103rii arterei femurale. Au observat de asemenea c\u0103 vaparea a condus la o reducere cu 17,5% a ritmului de circula\u0163ie a s\u00e2ngeului \u015fi cu 20% a oxigenului din vene, potrivit unei declara\u0163ii de pres\u0103.<\/p>\n

\nAutorul studiului, Alessandra Caporale, a spus \u00eentr-o declara\u0163ie de pres\u0103 c\u0103 aceste descoperiri sugereaz\u0103 faptul c\u0103 vaparea poate cauza schimb\u0103ri importante \u00een componen\u0163a interioar\u0103 a vaselor de s\u00e2nge. \u201e\u0162igaretele electronice sunt promovate ca fiind deloc d\u0103un\u0103toare, iar mul\u0163i utilizatori sunt convin\u015fi c\u0103 doar inhaleaz\u0103 vapori de ap\u0103\u201d, a spus Caporale \u00eentr-o declara\u0163ie. \u201eDar solven\u0163ii, aromele \u015fi aditivii din lichidul folosit, dup\u0103 evaporare, expun utilizatorii asupra multor riscuri pentru tractul respirator \u015fi vasele de s\u00e2nge.\u201d<\/p>\n
Ideea c\u0103 \u0163igaretele electronice nu sunt d\u0103un\u0103toare a \u00eenceput s\u0103 genereze reac\u0163ii negative pentru promovarea \u00een acest fel dup\u0103 ce copii au \u00eenceput s\u0103 inhaleze lichidele dulci. Recent, aproximativ 100 de adolescen\u0163i din 14 state americane au raportat probleme cu pl\u0103m\u00e2nii dup\u0103 vapare, inclusiv unele care au generat internarea, potrivit organiza\u0163iei EcoWatch. Problema a devenit at\u00e2t de grav\u0103 \u00eenc\u00e2t Centrul pentru Controlul Bolilor (Centres for Disease Control) din Statele Unite va lansa o investiga\u0163ie asupra consecin\u0163elor de s\u0103n\u0103tate ale fum\u0103rii \u0163ig\u0103rilor electronice. \u00cen timp ce anumi\u0163i doctori cred c\u0103 vaparea este mai s\u0103n\u0103toas\u0103 pe termen lung, efectele necunoscute pe o perioad\u0103 mai lung\u0103 ale inhal\u0103rii aromelor, particulelor, metalelor \u015fi altor componente incluse \u00een \u0163ig\u0103rile electronice ridic\u0103 \u00eengrijor\u0103ri, scrie CNN.<\/p>\n
\n\u00cen prim\u0103vara acestui an, un alt studiu publicat de CNN a indicat faptul c\u0103 aromele \u0163ig\u0103rilor electronice sau sucurile folosite pentru acestea au efecte toxice, inclusiv referitoare la supravie\u0163uirea celulelor. \u201eS\u0103 inhalezi substan\u0163e chimice \u00een pl\u0103m\u00e2ni este periculos\u201d, a spus Erika Sward, un purt\u0103tor de cuv\u00e2nt al Asocia\u0163iei Americane a Pl\u0103m\u00e2nilor (American Lung Association), care nu recomand\u0103 nim\u0103nui s\u0103 foloseasc\u0103 \u0163ig\u0103ri electronice, scrie Wired.<\/p>\n
\u201eNimeni nu \u015ftie ce va face inhalarea acestor vapori \u00een mod repetat. Este un experiment, sincer\u201d, a spus Dr.Robert Jackler, fondatorul unei organiza\u0163ii care cerceteaz\u0103 modul \u00een care se promoveaz\u0103 produc\u0103torii de produse din tutun (Stanford Research Into the Impact of Tobacco Advertising), la o audiere care a avut loc \u00een iulie. \u201eVom afla, peste ani, rezultatele acestui experiment\u201d, concluzioneaz\u0103 el.<\/p>\n
