Before ECigarettes Starter Kits I was smoking 10 to 20 Marlboro a day. I've been using my e-cig for 4 days and I've only smoked 5 Marlboro. Before I bought my e-cig I knew I wouldn't completely quit at 1st because I'm not only addicted to nicotine I'm also addicted to all of the other junk they put into Marlboro but I am definitely on my way to a smoke free life. I ordered the 18mg cartridges 1 lasts me 3 days. I enjoy the throat hit, it makes the experience almost like the real thing.
