Abstract Background The aim of this study was to investigate the effects of a web-based treatment program with therapist guidance for adults and adolescents with regular cannabis use from the general population. Methods A double blinded randomized controlled trial with a parallel group design was conducted (intervention group n = 151, wait-list control group n = 152). Follow-up 12 weeks from treatment commencement of a 13-module intervention. The primary outcome was frequency of cannabis use. Time by group interaction effects were modeled using generalized estimated equations and the instrumental variable approach was used to estimate the effect of intervention adherence. Results At follow-up, the intention to treat (ITT) analyses did not show any significant time by group effects. A significant association between intervention adherence and scores on the cannabis abuse screening test (CAST) was found. Secondary analysis excluding participants who had received other professional help revealed time by group effects for secondary outcomes gram cannabis consumed past week, number of dependency criteria and CAST score. Due to methodological limitations, these latter results should be interpreted with caution. Conclusions In this study we did not find a web-based treatment program with therapist guidance to be more effective than a waiting-list in reducing frequency of cannabis use. Trial registration The trial was pre-registered at ClinicalTrials.gov (NCT02408640) April 3, 2015

BACKGROUND Despite increasing demand for treatment among cannabis misusers in many countries, most misusers are not in treatment. Internet-based self-help offers an alternative for those hesitant to seek face-to-face therapy, though low-effectiveness and adherence issues often arise. Through adherence-focused guidance enhancement (AFGE), we aimed to increase adherence to, and the effectiveness of Internet-based self-help among cannabis misusers. OBJECTIVE A three-arm randomized controlled trial was conducted comparing the effectiveness of (1) an AFGE Internet-based self-help intervention with social presence (AFGE-SP), (2) a similar intervention with an impersonal service team (AFGE-ST), and (3) Internet access as usual (IAU, controls). METHODS From July 2016—May 2019, 575 cannabis misusers (70.6% males, mean age=28.3) not otherwise in treatment were recruited from the general population. The primary outcome was cannabis-use days over the preceding 30 days. Secondary outcomes included cannabis-dependence severity, changes in cannabis misuse disorder (CMD) symptoms, and intervention adherence. RESULTS All groups exhibited reduced cannabis-use days after 3 months (AFGE-SP: -8.2; AFGE-ST: -9.8; IAU: -4.2). AFGE-ST participants reported significantly fewer cannabis-use days than IAU controls (P = .01, d = .60); a similar reduction in the AFGE-SP (d=.40) group failed to achieve significance (P =.07). There was no significant difference between the two intervention groups. AFGE-ST patients also exhibited superior improvements in cannabis-use disorder, cannabis-dependence severity, and general anxiety symptoms after three months. CONCLUSIONS Adding an impersonal service team to the AFGE Internet-based self-help intervention significantly reduced cannabis use, cannabis use disorder, dependence severity, and general anxiety symptoms.
