The use of marijuana is a global problem and earlier evidence suggests an increasing trend in its use in all regions of the world. Despite years of research on marijuana and its effects on the human body, significant gaps in the literature exist. The purpose of this study was to investigate the knowledge, perception, attitude, and use of marijuana among senior high school students in the Bawku West District.

With a quantitative study approach, a cross-sectional study design was employed to answer the research questions. Cluster sampling is a method of probability sampling that is often used to study large populations, particularly those that are widely geographically dispersed. Researchers usually use pre-existing units such as schools or cities as their clusters. Zebilla Senior High/Technical School was chosen among the cluster of schools in the Bawku West District. After the cluster method was used to select the school, the convenient sampling method was used to select students for data collection. A non-probability selection technique called convenience sampling selects units for the sample based on which ones are most convenient for the researcher to access. Data management and analysis was done using the Statistical Package for Social Sciences (SPSS), now known as Predictive Analytics Software (PASW) version 20.
