I have been vaping for about 2 months. I started with a auto Smoketip kit. I purchased low nicotine cartridges because I am an extremely low nicotine cigarette smoker. I smoke Carlton Menthol. There is less than 1.5mg of nicotine in an entire pack of cigarettes with very low carbon monoxide. This is the lowest cigarette available but it does have a very strong throat hit, stronger than any of the other cigarettes that I used to smoke such as Virginia Slims Menthol and Marlboro Menthol. I have now ordered manual KR batteries and higher nicotine carts and I like them better but I still can't quit. Any suggestions? I would hate to go above 11mg of nicotine!!
