Final answer:
The fastest-acting nicotine substitute is not the nasal spray. Nicotine replacement therapy includes methods like chewing gum, lozenges, and skin patches.
Step-by-step explanation:
False. The fastest-acting nicotine substitute is not the nasal spray. One approach to combat nicotine addiction is nicotine replacement therapy, which includes methods like chewing gum, lozenges, and skin patches. These methods provide a dose of nicotine that is enough to overcome cravings but too small to produce a high. Nasal spray is not commonly used as a nicotine substitute, and other methods are more effective.
