I do lean to a degree on the 'choice' side of the argument. It doesn't matter what it is, there's always a choice. Cigarette smokers are an example - you see a number who, when without quick access to one, will start asking around to anyone if they have a spare cigarette.
As a smoker, I've always considered this a bit rude - it's one thing to ask a friend who you may happily share things with, but pestering some random stranger on the street has never sat well with me. Do you need a smoke that badly?
Having a degree of dependency on something is one thing. How you handle that is another thing entirely.
