What is the recommended dosage of nicotine gum for someone smoking more than 25 cigarettes a day?

For individuals who smoke more than 25 cigarettes a day, using a higher dosage of nicotine gum is recommended to effectively manage withdrawal symptoms and cravings during the quitting process. The rationale behind suggesting 4 mg of nicotine gum for heavy smokers is that this dosage provides a sufficient amount of nicotine to match the higher dependence on nicotine due to their smoking habits.

Using the 4 mg gum helps to mimic the nicotine intake they would typically receive from cigarette smoking and reduces the likelihood of relapse by adequately satisfying cravings. The 2 mg gum is generally more appropriate for lighter smokers, and higher doses like 6 mg or 8 mg are not standard for nicotine replacement therapy, as they could lead to excessive nicotine intake and potential side effects. Hence, the correct recommended dosage for someone smoking over 25 cigarettes a day is indeed 4 mg.
