Four methods of smoking withdrawal were compared in patients with smoking related diseases attending a hospital or chest clinic. Reinforcing verbal advice with a booklet or with a booklet together with nicotine or placebo chewing gum did not result in greater success than verbal advice alone. Roughly a quarter of those patients who denied smoking had carboxyhaemoglobin and plasma thiocyanate concentrations typical of smokers. At the end of a year 150 out of 1550 patients (9.7%) had successfully stopped smoking.
在一家医院或胸科诊所就诊的患有吸烟相关疾病的患者中,对四种戒烟方法进行了比较。用一本小册子或一本小册子加上尼古丁或安慰剂口香糖来强化口头建议,并不比单纯的口头建议更成功。大约四分之一否认吸烟的患者的碳氧血红蛋白和血浆硫氰酸盐浓度与吸烟者的典型浓度相同。一年后,1550名患者中有150名(9.7%)成功戒烟。
