I believe it ends up why one was smoking (or using any substance in any way) in the first place.
If you're enjoying and it just becomes a (not super healthy-but not my point here) everyday habit, sure, you probably won't have withdrawal symptoms.
If you're using something to get away from some reality in life that is too unbearable, and that unbearable thing is still a matter when you want to quit, then it'll be hard. But it's not actually the substance (excluding hard/chemically super addicting class of substances like heroin or sugar) but the fact of facing the problems.
