Ya they help people quite but there also an alternative to real cigs, they get rid of all the nasty shit in cigs like cow shit tar and carcinogens. There only water vapor and nicotine so you can even smoke them in doors. Plus its a million times cheaper then smoking. Im 20 by the way and dont plan on smoking them for ever i just cant quite and they dont make you hack all sorts of nasty shit up or fuck with your breathing.
heres a few ecigs i have.
