i have never been a habitual smoker. but i am a nervous, anxious person and occasionally smoke cigarettes for the calming effect. its got me through getting my drivers license. there are things i do to keep myself from becoming addicted. (First advantage is I never tried it when I was a teen, thats probably the biggest help) I never smoke for work/daily related stress and on the occasion that i do have a cig i make sure to not have another that same day. Cigarettes are gross and i've never had the urge to have a smoke for the smoke's sake.
The 1 thing the nay sayers have against ecigs is its still addictive. But that argument means nothing to me since I'm not an addict.
I wouldn't even care if the same restrictions applied to e-cigs as regular cigs. Just let me buy them. They are not available in my town, and online stores won't ship them here.
