What should be done for a regular user as discussed in the scenario about the girl?

The most appropriate choice is an intervention group, as it provides a structured environment where individuals can receive support from peers and professionals who understand their challenges. Intervention groups are designed to help regular users by facilitating discussions about their experiences and encouraging positive change through shared accountability and collective motivation. These groups also typically offer resources for dealing with substance use and provide coping strategies, creating a supportive community that empowers individuals to make healthier choices.

While encouraging someone to quit can be well-intentioned, it may lack the necessary framework or support that an intervention group provides. Legal action is generally not a constructive approach for individuals dealing with substance use, as it can exacerbate the situation and push them further away from seeking help. Family counseling could be beneficial, but it may not directly address the personal challenges of the regular user in the same way an intervention group would, as it primarily focuses on family dynamics rather than the individual's specific substance use issues.
