I have smoked for approximately 23 years with bouts of chewing tobacco, quit immediately after trying my first e cig, threw the balance of my pack of smokes in the garbage and haven’t looked back, no cravings, no withdrawal symptoms just a true pleasure in vaping and satisfying nicotine cravings, now i am almost of nicotine but that was never the intent, i do see myself going off nicotine but continuing to vape. i had tried many NRT’s they were awful and dangerous, the gum resulted in several horrible nicotine overdoses, its very difficult to bite bite stop. i had symptoms of a heart attack with cold sweats, low blood pressure and almost fainting spells – with gum its difficult to control nicotine intake. I am happy and healthier on the road to recovery, i have since stopped snoring and lung capacity and breathing quality has improved dramatically. Thank you for bringing this amazing product and technology to the public.
