This trial investigated the effects of access to an Internet-based screening and brief intervention site for illicit drug users. This article adds to previously published results from the 3- and 6-month follow-ups by extending the follow-up period to 12 months and reporting changes in substance use between the 6- and 12-month follow-ups.


In total, 202 Internet help-seekers with illicit drug use, 15-70 years old, were randomly assigned to either an intervention group that received Internet-based screening and brief intervention via or to an assessment-only control group. The primary outcome measure was the Drug Use Disorders Identification Test consumption questions (DUDIT-C) score, and secondary outcome measures were the DUDIT, Alcohol Use Disorders Identification Test consumption questions (AUDIT-C), and AUDIT scores, as well as the proportion of drug abstainers and participants making a clinically significant change in their alcohol and other drug use.


DUDIT-C, DUDIT, AUDIT-C, and AUDIT scores remained stable between the 6- and 12-month follow-ups. However, 12 months after recruitment, 34.3% of those who used had changed their alcohol use to a clinically lower level compared with the 21.8% of the controls. Also, none of the users increased their level of alcohol use during this 12-month period, whereas 5.0% in the control group did so.


Despite no changes in illicit drug use from the 6- to 12-month follow-up for both the intervention and control group, seems to be more effective than assessment only for reducing alcohol use among illicit drug users over a 12-month period.
