Ethics approval and consent to participate
: The study was carried out in accordance with the ethical standards, Declarations of Helsinki. Approval was obtained from the Institutional Review Board (IRB) at An-Najah National University in Palestine prior to the research conduction and the general police department approval was obtained. Confidentiality was assured by keeping the data in a safe place and by using codes instead of names. All the information were available for the research team only. Due to the stigma and legal issues surrounding alcohol and drug use, confidentiality was highlighted in all written and oral communications. Informed consent was obtained. Participation in this study was voluntary, and the confidentiality of the students was ensured, as the questionnaire was anonymous and did not include any questions that will lead to personal identification.
