[Are they the same in meaning? Which one means that he decided not to smoke from now on? Which one means that he quit smoking completely and that he will never smoke again?]

2. "He quit smoking" also means that he decided to stop smoking. However, it carries a stronger connotation that he has completely given up the habit and does not plan to smoke again in the future.

3. "He gave up smoking" has a similar meaning to "He quit smoking" in that it suggests he has permanently ended the habit. It implies that he has made a definitive decision to quit smoking and will not resume the habit.

In summary, all three phrases convey the idea that he has taken action to stop smoking. However, "He quit smoking" and "He gave up smoking" have a stronger implication that he has quit for good and will not smoke again in the future, while "He stopped smoking" is a more general statement indicating he has ceased smoking at the present.
