Vaping is the labeled as one of the best weening techniques for treating someone's nicotine addiction. E-liquids commonly come in 24mg, 18mg, 12mg, 6mg, and of course 0mg. If there is zero nicotine you will not feel anything. Zero nicotine is useless, unless of course you are "stepping" down in an effort to treat your nicotine addiction, in which it is utilized as an oral fixation. A large majority of the people that vape 0mg because it's the not-so-new "cool" thing to do. Don't be one of those people.
Depending on the nicotine level and of course your tolerance to nicotine, vaping can certainly put you on your ass for a few minutes. Personally, I would rather dip tobacco rather than vape for a source of nicotine. I vaped for two years and stepped down from 18mg to 0mg within a few months. Then simply I used vaping as an oral fixation before I picked up dipping. I will certainly vape again when I choose to quit dipping.
