Hi. I want to quit smoking analogs. I'm 26 yo now, and ive started smoking when i was 6, since 9 it was more than one pack per day

Im very addicted, when im not smoking for couple hours I feel physical pain, and e-cigarette sounds like a good way to quit smoking for me. But... ive already tried e-cigarette once, some lady who was selling them on the street offered couple puffs for free, and it didnt have any effect on me. Ive made more than dozen very deep puffs, until I've got headache, but still my physical need for cigarette was unsatisfied. Before when i was trying to quit smoking, Ive used snuff and other tobacco products and nicotine chewing gums, also with no luck - they didnt have any effect when I was starting feeling bad.
I think that maybe im not addicted to nicotine, but to tar, or other chemicals in cigarettes. What do You think? Does real e-cigarette (not cheap, disposable one, which this woman offered me to try) gives me any chance of quiting smoking? Are there any e-liquids available with real, breath-taking taste of strong cigarettes?
This post may sound like provocation, but it isn't.
