Tobacco withdrawal is best described as which of the following?

• A. Daily use of tobacco for at least several weeks
• B. Abstinence or reduction in tobacco use followed by 24 hours of signs or symptoms
• C. The signs or symptoms in B cause clinically significant distress or impairment
• D. Withdrawal signs last only 2-3 hours

Answer: (B)

Tobacco withdrawal occurs after stopping or reducing nicotine use, with symptoms appearing within roughly a day. The best description fits this pattern: abstinence or reduction in tobacco use is followed by signs or symptoms within 24 hours. This timing reflects the body's dependence on nicotine and the rebound effects when intake stops. The other statements miss the key point. Daily, long-term use describes regular consumption, not the withdrawal process. Symptoms lasting only a few hours underestimate the typical course, which lasts longer than 2–3 hours. And while withdrawal can cause distress or impairment, the defining feature is the emergence of withdrawal symptoms after cessation or reduction within about 24 hours, not the presence of impairment alone.
