yes... you can get different levels of nicotine, from retardedly high (36mg/ml) to none (0mg/ml)
it is essentially a nicotine inhaler
so it can be used like the patch and as a step down device
or it can be used as a replacement for smoking
i have some friends who use them about 50% of the time and cut back on regular smokes
i have been using mine exclusively since easter sunday... i smoked one clove at claytons party... and that was simply because i like cloves... other than that i havent had a regular cigarette in a month
it is not exactly like smoking, but it is close enough that i do not miss cigarettes at all... this is actually a big part of why i bought the model i did... it looks and feels very similar to a regular cigarette, so it doesnt feel like a novelty or toy to me... there are several other models out there, some similar, some drastically different, most performing different as well... some better, many worse...
there were a few times when i first started using it that i kinda wanted a regular cigarette... but the feeling went away after a few seconds... now, i couldnt give a shit about having a regular cigarette... in fact i think they smell like shit now
i am not of the belief that electronic cigarettes are "healthy"... but i know that i do feel considerably better since i started using them rather than regular cigarettes... and seriously, they
cant be worse
i bought mine as a cigarette replacement... i like smoking and did not want to quit... i use it the same way that i would a regular cigarette... i do not smoke in my car, i do not smoke inside... i enjoy having smoke breaks at work, i enjoy having a smoke after eating, i enjoy having a smoke at the bar, i enjoy having a smoke while drinking coffee with friends
i do notice that i smoke this less than a regular cigarette... it is not uncommon for me to take 1-3 drags and put it away, rather than the 10+ it would take me for a regular cigarette... i also find that i smoke it less often... probably smoking the equivalent of a pack every 3-4 days
the model i have is a 2 piece design (loong totem) with disposable atomized cartridges (as opposed to the more common 3 piece designs) i got it from epuffer.com
i also got some of the liquid so that i can refill my cartridges and get the full life out of the atomizers in them... i can generally get about a week on 1 cartridge now... i top off the carts with 2-4 drops of fluid at night and they are generally good for the whole next day... 1 cart costs me about $1.70 including refill liquid for the week, as opposed to about $35+ i was spending (or $15ish i would be spending at my current smoking level) on Marbs... so after my initial buy in, i am definitely spending less money (i am actually ahead of the game now, if i was buying cigarettes i would have spent the money it cost me to get the e-cig starter kit and the liquid by now)
there are a LOT of options out there, i found out about these last summer, and have done a lot of research on the different models and brands since then... if anyone has any questions, please ask... there are a lot of shitty models and companies that would be best left alone
the model i have works well for me... it is not the model i would recommend to everyone though
there are different designs and models that would work better based on your wants and needs...
its not cheap to get into... but so far, i have no regrets
