What type of intervention is considered effective for smoking cessation?

B is considered the correct answer because nicotine replacement therapy (NRT) combined with behavioral interventions has been shown through research to be one of the most effective approaches for smoking cessation. NRT helps to reduce withdrawal symptoms and cravings by providing the body with a controlled dose of nicotine without the harmful substances found in cigarettes. When combined with behavioral interventions, which may include strategies to change habits and cope with triggers, this approach addresses both the physiological and psychological aspects of nicotine dependence, leading to higher rates of successful quitting.

Behavioral interventions provide support in managing cravings, developing coping strategies, and reinforcing positive changes, thereby enhancing the effectiveness of NRT. This combined approach leverages the strengths of both complementary therapies to maximize the likelihood of long-term abstinence from smoking.

The other options do not offer the same level of effectiveness as the combination of NRT and behavioral interventions. Relying solely on behavioral therapy or medications prescribed by doctors, while potentially helpful, does not address the immediate withdrawal symptoms that many individuals face when quitting smoking. Additionally, support from family members can be beneficial but is often most effective when integrated with structured therapeutic approaches like NRT and behavioral strategies.
