I started vapeing about two weeks ago to replace my habit of casually smoking cigars and pipes. All research indicated I should opt for a 18mg nicotine level. Placed an order for some tobacco e-juice samples in 18 and became acclimate to the difference between grown tobacco and juice. I have never felt any nicotine addiction and basically smoked as a pastime and relaxation routine maybe two or three times a week. Some of my cigar and pipe tobacco selections have given me a nicotine rush in the past. Now I feel that the purity and % in the juice is too strong as I have a slight buzz going that has lasted for a few days now. I wake up in third gear as opposed to neutral (if you know what I mean). The 18mg samples have been passed on to a heavy cig smoking friend. Current issue I have is that another sampler was in the mail yesterday and it was thought at order time that 18 would be spot on. I am eager to see how the flavors pan out. My thought is to contact vendor and see if another sampler can be purchased at 0mg and packaged in double sized bottles so I can mix what I already have. Is this feasible and if so would I basically wind up with 9mg juice? Lastly given the purity of nicotine in juice could that newly adjusted level still potentially be to strong giving my past tobacco smoking experiences? I know that straight 0mg is an option, but I was hoping to accurate simulate the true smoking experience. So far I have been very impressed with some of the tobacco flavors that are really close to organically grown stuff.
