Intervention group

EXPERIMENTAL

Each participant will receive the telephone that will be delivered by a trained peer supporter using the Ask, Warn, Advise, Refer and Do-it-Again (AWARD) model. For the advice steps, participants will be asked about the priority they place on engagement in health-related lifestyles. A brief intervention on the selected health-related lifestyle will be given. In addition, they will be informed that they will receive instant messaging via WeChat or WhatsApp to assist them to adhere to their schedule of the desirable health-related lifestyle throughout the study period. For the first 6 months of the study period, peer supporters will send WhatsApp or WeChat messages approximately once per week to the participants to remind them to adhere to their schedule of the desirable health-related lifestyle. In addition, the participants will receive four independent 1-minute videos which focus on the health risks associated with abusing drugs and the benefits of quitting drugs.

Control Group

PLACEBO COMPARATOR

Trained peer supporters will answer calls from potential participants and explain the nature and purpose of the project to them. Each participant will then receive a brief intervention over the telephone that will be delivered by a trained peer supporter using the Ask, Warn, Advise, Refer and Do-it-Again (AWARD) model. Participants will be asked to quit drugs immediately or progressively. In addition, they will be informed that they will receive instant messaging via WeChat or WhatsApp from peer supporters to assist them to adhere to their schedule of quitting drugs throughout the study period. For the first six months, participants will receive four independent 1-minute videos which focus on the health risks associated with abusing drugs and the benefits of quitting drugs without any schedule of the desirable health-related lifestyle throughout the study period.
