I am 21 years old and I have got a bad habit of smoking 1-2 cigarettes a day. The reason I smoke is that it helps me to relax and relaxes my brain for sometimes but I want to quit smoking because I can feel I have lost my stamina very much. What are the options available for me and also do tell me about nicotine gums. And also how could I make my lungs healthy and reduce tar. I have been smoking for 3 years.
