The goal of this article is to determine whether reducing cigarette consumption increases the likelihood of future cessation. Data from 3,385 participants who originally took part in the Community Intervention Trial for Smoking Cessation completed detailed tobacco use phone surveys in 1988, 1993, and 2001. Between 1988 and 1993, 15% of smokers reduced their daily cigarette consumption by 50% or more, and 9% of the entire baseline sample maintained this reduction in 2001. Those who reduced more than 50% were 1.7 times more likely to quit smoking by 2001 compared with those who did not reduce. Few smokers are able to reduce their consumption by 50% or more, although those who do are more likely to quit compared with those who do not.
本文的目的是确定减少香烟消费量是否会增加未来戒烟的可能性。3385名最初参与社区戒烟干预试验的参与者的数据来自于1988年、1993年和2001年完成的详细烟草使用电话调查。在1988年至1993年期间，15%的吸烟者将其每日香烟消费量减少了50%或更多，并且在2001年，整个基线样本中有9%的人保持了这种减少。与未减少的吸烟者相比，减少量超过50%的吸烟者在2001年戒烟的可能性高出1.7倍。很少有吸烟者能够将其消费量减少50%或更多，尽管与未减少的吸烟者相比，成功减少的吸烟者更有可能戒烟。
