Smoking

Do you think smoking is taught? Some of the smokers that I know pretty much all of their parents smoke (I don't know a lot of smokers so I'm not trying to be over dramatic these are just my experiences). Do you think this nasty habit is learned through them? Do you think children see smoking as a normal thing and when they can smoke they will or they are more prone to start smoking themselves? Also do you smoke and did your parents smoke?
