Data from a seven-year follow-up study of heroin addicts were analysed to show group trends. Time spent in various activities was quantified for each person for each year of the follow-up period and used to provide a composite life history. Time spent by the sample using drugs has decreased over the follow-up period. The most marked decrease appeared in the use of heroin, but the analysis suggests that a hard core of heroin users still used heroin several years after coming to the clinic. There seems to be an overall congruence between abstinence and non-clinic attendance. For this sample the use of illegal opiates without attending a clinic was relatively rare, and total time spent in hospitals and in prisons was rather small. Death occurred randomly during the follow-up period.
对海洛因成瘾者进行的一项为期七年的随访研究数据进行了分析，以显示群体趋势。在随访期间的每一年，对每个人在各种活动上花费的时间进行了量化，并用于提供一份综合生活史。在随访期间，样本中使用毒品的时间有所减少。最显著的减少出现在海洛因的使用上，但分析表明，一部分顽固的海洛因使用者在进入诊所几年后仍在使用海洛因。戒毒与未就诊之间似乎总体上是一致的。对于这个样本来说，未就诊而使用非法阿片类药物的情况相对较少，在医院和监狱中花费的总时间也相当少。在随访期间死亡是随机发生的。
