Many people see vaping constantly as a problem but in all actuality, nicotine is not the enemy. Nicotine is not the reason we all switched from analogs to e-cigs. We switched because of all the tar, plaque, carcinogens, and many other health reasons. Nicotine is NOT carcinogenic, medical research shows that it can make us feel better, improve concentration, memory and help prevent and combat a number of serious diseases.
