Smokers and non-smokers have many differences, and very few similarities. I am one of those people who have been subject to addiction and got into the habit of smoking even though I do realize that us smokers are looked down upon by many people. Many restaurants and public places have become non-smoking, which prevents smokers from going certain places. Most people who smoke realize the harmful affects, but addiction is too strong to overcome that most of the time. For me I don't think it's as much the addiction, but how cigarettes help me relax and relieve stress.
One of the main reasons non-smokers look down on smokers is because most of them realize the harmful affects, but continue to smoke because they are addicted. People who smoke tend to spend a lot of money on cigarettes that they could be spending on something that is more necessary than cigarettes. People who smoke generally have a yellowish tint on their fingernails and teeth from the tar in the cigarettes. Bad breath is also a common trait to people who smoke, which could be helped by breath mints or gum, but most people who smoke don't carry those items around with them. Many people who smoke would like to quite smoking to prevent certain future health problems, but can't because they are addicted.
Non-smokers, however, do not understand us smokers because they have never experienced addiction for themselves. Non-smokers do not have to waste their money on cigarettes because they do not smoke. Non-smokers do not have to worry about stained fingernails or teeth either, which helps them have a somewhat cleaner appearance. They could, however, have bad breath depending on what kind of food they eat and how often they brush their teeth. In general non-smokers...
