Smoking involves inhaling the smoke of burning tobacco in cigarettes, pipes, and cigars. It is both a physical and psychological addiction with serious health consequences. People smoke for various reasons like looking mature, fitting in with friends, relaxation, and coping with problems. Smoking can cause immediate effects like loss of appetite and coughing as well as long term health issues like cancer, heart disease, and infertility. Quitting smoking requires mental preparation by setting a date, informing others, and removing smoking-related items from one's home to adjust to becoming a non-smoker.
