: This proposed study (Version 1, 16 June 2020) has obtained ethical approval from the Institutional Review Board (UW 20–395) and has been registered at ClinicalTrials.gov (NCT04672746). All participants will be well informed of the aims and content of the study. The participants will have the right to terminate their involvement in the study at any time without consequences. As youths typically wish to keep knowledge of their drug-abusing status from their parents and join the service anonymously, verbal consent to participate in the project will be obtained from potential participants before the provision of phone counselling, and written consent from parents will not be required; this has been discussed with and approved by the ethics committee. The participants’ confidentiality will be ensured, and their verbal consent and counselling content will be audio-recorded.
