It's kind of bizzare how if you think of someone who smokes, you think of someone who smokes WAY TOO MUCH. Like for some reason you're either a pack-a-day chain-smoker or disgusted by cigarettes. I used to smoke maybe a pack a month. I haven't bought cigarettes in a long time but I still like to have one now and again if I'm offered one. I don't know why it's assumed there is no grey area between total abstinance and horrible addiction.

When it is said that smoking is extremely hazardous to your health, there is no qualifier for "smoking" to say exactly HOW MUCH smoking would be extremely hazardous. Of course heavy smoking is bad for you. But eating Hamburgers is extremely hazardous to your health if you eat TWENTY A DAY.
