The incidence of substance use, abuse and dependence seem to be increasing (1). It is probable that underlying mental illness, may reinforce individual's continuing substance indulgence (2), and If not intervened early, the consequence of this not only affects individual health, but also poses the threat of them procreating future sufferers.

To detect mental illness at an early stage, in young adults with drug indulging behavior, and early intervention could be attempted.

A pilot project has been undertaken, for young adults (16-20 years) with concurrent disorder providing integrated intensive treatment program for six months. 12 patients were enrolled the study and 8 patients completed the study. A questionnaire has been devised to detect the probable existence of concurrent disorders. Assessment in all tridimensional spheres and intervened concurrently by the multidisciplinary team members. The outcome measures with the patients and the personnel were assessed by an independent assessor. The sensitivity and specificity of the devised questionnaire, has been measured.

There is significant correlation between underlying mental illness with drug indulgence and specific drug preference with type of mental illness have been elicited. The outcome measures along with the sensitivity and specificity of the questionnaire have been found significantly positive.

It seems that the integrated treatment program is quite effective although resource consuming.

Small sample and limited duration which needs further replication.
