Spontaneous remission from alcohol, tobacco, and other drug abuse: seeking quantitative answers to qualitative questions.

A quantitative review of the substance abuse literature revealed a mean general prevalence of spontaneous remission from alcohol, tobacco, and other drugs abuse of 26.2% when a broad definition of remission was employed and 18.2% when a narrow definition was implemented. From the results of this review, it was concluded that few meaningful differences exist between spontaneous remitters and persons who either continue misusing substances or remit through treatment on pre-remission measures of prior drug involvement. Of the factors cited by self-remitters as important in facilitating their desistance from substances, the present review found that health concerns, pressure from friends and family, and extraordinary events were instrumental in initiating spontaneous remission, while social support, non-drug-using friendships, willpower, and identity transformation were pivotal in maintaining change. Evidence is presented to indicate that spontaneous remission from alcohol and illicit drugs and spontaneous remission from tobacco smoking may differ in several key respects.
