Nicotine gum comes in 2mg or 4mg strength. It is meant to be used periodically and as needed to help with cravings. The gum must be used properly (not like regular chewing gum) in order for it to work. There is a schedule of use for the gum inside the package instructions. Smokers are usually advised to use up to 1 piece per hour (without exceeding the daily max. dose of 24 pieces) for the first several weeks, and then taper use of the gum gradually (use less gum over time).
