I occasionally use a 2mg piece of nicotine gum as a pick me up if I've already had too much caffeine or if it's late at night (or if I'm at a conference where I'm getting little sleep), and I certainly feel the stimulant effect and nothing else. Never had any sort of tolerance, never felt any draw to take it except in the sense of "Boy I'm really dragging, I need a stimulant. Should I get coffee or a piece of gum?".
Most weeks I use none, some conferences I've used 2 pieces a day every day for 4-5 days straight. No problems stopping afterward.
