Pharmacological treatment increases quit rates by approximately how many times?

• A. 1-2X
• B. 3-4X
• C. 2-3X
• D. 4-5X

Answer: (C)

Pharmacological aids for nicotine dependence raise the chance of quitting by about two to three times compared with placebo or no pharmacotherapy. This boost comes from addressing withdrawal and cravings, keeping nicotine levels steadier to prevent spikes in urges, and reducing the reinforcement of smoking, which helps people maintain abstinence during and after the quit attempt. Across common therapies—nicotine replacement options, bupropion, and varenicline—the typical improvement in abstinence at follow-up sits in the two- to three-fold range. Some agents in certain trials show higher gains, but two to three times is the best general estimate for typical practice.
