Progression of addiction careers in young adult solvent misusers.

Four case histories of a representative sample of young adult glue sniffers who had progressed to using illicit drugs or abusing alcohol or both contained several common factors that may have been relevant in the transition. For example, all had suffered parental deprivation or rejection in childhood leading to a state of chronic stress, and all had progressed from sniffing glue to inhaling heroin and thence to "snorting" and injecting heroin. The exact reason for the transition from glue sniffing to misusing other substances was not clear. Nevertheless, although these cases represent only a minority of glue sniffers, the problem of transition may be more common than hitherto supposed.
