Do I have to be present for the whole session for it to work?

Yes. The session is designed to first prepare your unconscious and then use hypnosis to provide it clear instruction about becoming a nonsmoker. Each portion builds upon the next.

Can everyone be hypnotized?

Hypnosis is a natural state that we go in and out of throughout the day, so everyone can be hypnotized as long as they want to be. The people that may not receive the full benefit of the hypnosis are those who are on mind altering medications or drugs.
