A large proportion of patients treated for substance dependencies have attempted suicide. Scarce empirical evidence exists regarding their prognosis. ⋯ The likelihood of recovery from drug dependence did not differ between patients who did or did not attempt suicide. Among suicide attempters who recovered from substance dependence, the frequency of Major Depression Disorder was significantly lower compared to admission, but its prevalence was nearly three times higher than that found in the general community.
