The half-life of saliva cotinine and its accuracy at detecting light or intermittent smoking were examined. Five subjects provided daily saliva samples for 23 days and quit smoking on day 4. An average of 2.8 days was required for saliva continue to drop below the cutoff for classification as a smoker. All smokers smoked intermittently at various times after day 9. In most cases the smoking of one or two cigarettes was detected in the saliva sample on subsequent days. Saliva cotinine was sensitive to low rates of smoking and to intermittent smoking.
研究了唾液可替宁的半衰期及其在检测轻度或间歇性吸烟方面的准确性。五名受试者连续23天每天提供唾液样本,并在第4天戒烟。唾液可替宁水平平均需要2.8天才能降至低于吸烟者分类临界值。所有吸烟者在第9天后的不同时间均为间歇性吸烟。在大多数情况下,随后几天的唾液样本中检测到吸了一两支烟。唾液可替宁对低吸烟率和间歇性吸烟敏感。
