Don't smoke it, it shortens your life span by 10 years and that doesn't even include the increased chance for lung cancer. But then again smokers will literally do anything except quit smoking. One time I was at a hospital and I saw a woman coughing, take a spray from an inhaler, stop coughing, then immediately pulled out a cigarette took a puff and cough so hard blood came out. Quitting smoking is extremely difficult so it's best to just not get addicted to begin with.
