People who do not smoke, often can not figure out why someone would start smoking, or continue to do so, when the dangers and side effects of it are so obvious. nnNon smokers don’t understand why smokers don’t simply throw away their cigarettes and be done with it. Smokers do not do this because smoking tobacco isn’t simply a bad habit. It is incredibly addictive. Health professionals believe that it is just as addictive as any street drug, and because it is legal, people tend to believe that it is less harmful then it really is.nnWhen the chemicals in cigarettes are inhaled, they reach the smoker’s bloodstream, lungs and brain, which has long lasting effects that are very addictive.
