Summary
This study evaluates CANreduce 2.0, a web-based tool for problematic cannabis users. It assesses if the tool, with or without psychological support, effectively reduces cannabis consumption compared to standard care.
Area of Science:
- Clinical Psychology
- Digital Health Interventions
- Substance Use Disorders
Background:
- Cannabis is Europe's most used illicit drug, with rising treatment demand in Spain.
- Problematic cannabis users often do not seek traditional treatment.
- Web-based tools like CANreduce 2.0 offer a potential solution for managing cannabis use.
Purpose of the Study:
- To evaluate the effectiveness of the Spanish version of CANreduce 2.0 (CANreduce-SP) in reducing cannabis use.
- To determine if adding psychological support to CANreduce-SP enhances its efficacy.
- To compare CANreduce-SP interventions against treatment as usual (TAU).
Main Methods:
- A three-arm randomized controlled trial (RCT) protocol is described.
- Intervention groups: (1) CANreduce-SP with psychological support, (2) CANreduce-SP alone, (3) TAU.
- Primary outcome: change in weekly cannabis use days; secondary outcomes: other cannabis use measures. Mental disorders explored as predictors.
Main Results:
- This section is for results that will be available after the study is completed.
Conclusions:
- The study will determine CANreduce-SP's effectiveness in reducing cannabis use frequency and quantity.
- It will investigate whether psychological support improves outcomes for problematic cannabis users.

A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
