Elektroniskā cigarete (saīsinājumā e-cigarete) jeb veips (no angļu: vape, saīsinājums no vaporizer — 'iztvaikotājs') ir ierīce, kas imitē tabakas smēķēšanu. Tas sastāv no izsmidzinātāja, barošanas avota, piemēram, akumulatora, un konteinera, piemēram, kasetnes vai tvertnes. Dūmu vietā lietotājs ieelpo tvaikus.[1] Tādējādi e-cigarešu lietošanu bieži sauc par "veipošanu".[2] Izsmidzinātājs ir sildelements, kas iztvaicē šķidru šķīdumu, ko sauc par e-šķidrumu[3], kas ātri atdziest par sīku pilienu, tvaiku un gaisa aerosolu.[4] Tvaiki galvenokārt satur propilēnglikolu un/vai glicerīnu, parasti ar nikotīnu un aromatizētāju. Tās precīzais sastāvs atšķiras un ir atkarīgs no vairākām lietām, tostarp lietotāja uzvedības.

Dažādi e-cigarešu veidi no 2015. gada, tostarp vienreizējās lietošanas e-cigarete, uzlādējama e-cigarete, vidēja izmēra tvertnes ierīce, liela izmēra tvertnes ierīces, e-cigārs un e-pīpe

E-cigaretes tiek aktivizētas, ieelpojot vai nospiežot pogu.[2][5] Dažas izskatās kā tradicionālās cigaretes,[2][6] un lielākā daļa veidu ir atkārtoti lietojamas. [8]

Nikotīns izraisa lielu atkarību.[9][10][11] Lietotāji kļūst fiziski un psiholoģiski atkarīgi.[12] Zinātnieki nezina, cik kaitīgas ir e-cigaretes ilgtermiņā[13][14], jo ir grūti nošķirt tvaicēšanas ietekmi no veipošanas sekām, kad tik daudz cilvēku gan veipo, gan smēķē. [a][15] E-cigaretes nav izmantotas pietiekami plaši vai pietiekami ilgi, lai pārliecinātos.[16][17][18]

Veipošana, visticamāk, ir daudz mazāk kaitīga nekā smēķēšana, taču tomēr kaitīga.[19][20] E-cigarešu tvaiki satur mazāk toksīnu nekā cigarešu dūmi, zemākā koncentrācijā. Tvaiki satur kaitīgu vielu pēdas, kas nav atrodamas cigarešu dūmos.[20] Nikotīnu saturošas e-cigaretes ir efektīvākas par nikotīna aizstājterapiju (NAT) smēķēšanas atmešanai.[21][22] Tomēr e-cigaretes nav tikušas pakļautas tikpat stingrām pārbaudēm kā lielākajai daļai nikotīna aizstājterapijas produktu[23], un brīdinājumi par ietekmi uz veselību var mudināt smēķētāju atmest veipošanu.[24]
