I myself don't smoke but I've successfully converted 5 people to e-cigarettes. I always gave them a cheap egos and asked them what they liked an disliked about it. If there was enough "smoke" taste, nicotine etc. I made diy liquids especially for them. This worked really well, but now I have a special case, the person has been smoking van nelle for about 20 years. He tried what I gave him but dislikes the taste of the liquid. If I can make one that tastes similar to his van nelle tabbacco he would use it though. I've tried google but I couldn't find anything so far. Hopefully somebody can help, I only wanna make an extract of the van nelle tabbacco as last resort.
