give me in paragraph form; Conducting a small-scale preliminary investigation to test the feasibility and validity of the research before launching a full-scale study. This could include:

1. Identifying and recruiting a sample of cannabis users within the target age group in the Humilaveka Goroka District (10 – 20).
2. Conducting interviews or surveys to gather data on their patterns of cannabis use, reasons for use, perceived benefits and risks, and any associated health or social issues (5-15).
3. Analyzing the data to identify any trends or patterns that can inform the design of a larger study.
4. Assessing the feasibility of recruiting and retaining participants, collecting data, and implementing the study protocols in the local context.

In order to test the feasibility and validity of a larger research study on cannabis use among individuals aged 10-20 in the Humilaveka Goroka District, a small-scale preliminary investigation will be conducted. First, a sample of cannabis users within the target age group will be identified and recruited. Interviews or surveys will then be conducted to gather information on their patterns of cannabis use, reasons for use, perceived benefits and risks, and any associated health or social issues. The data collected will be analyzed to identify trends or patterns that can inform the design of a larger study. Additionally, the feasibility of recruiting and retaining participants, collecting data, and implementing study protocols in the local context will be assessed. These preliminary steps will help ensure the success of the full-scale research study.
