Study Arms (3)

Phase 1: A video competition for anti-drug abuse

OTHER

Phase 1 aims to increase the public awareness of hazardous effects of drug abuses and existing resources available for drug abusers through a video competition. We will co-organize a video competition for anti-drug abuse with C.H.O.I.C.E. The competition will appeal to the participation of all children (aged 13-18) living in the four targeted districts.

Behavioral: A video competition

Phase 2: Developing a community-based network

OTHER

Phase 2 aims to develop a community-based network through training anti-drug ambassadors (ADAs). We target to recruit a total of 150 children aged 13 - 18 as ADAs through secondary schools and community centres in the four targeted districts by sending invitation letters. The content of the workshop will be designed by our expert panel. The content of the workshop will include (1) hazardous effects of drug abuse especially less psychotropic drugs such as Cannabis, (2) signs and symptoms of drug abuse particularly less psychotropic drugs like Cannabis, (3) alternatives to drug abuse, (4) community resources available, and (5) how to refer drug abusers. Besides, all children will be taught to use the AWARD model for referrals in the workshop.

Behavioral: A training workshop

Phase 3: A mass promotional campaign

OTHER

Phase 3 aims to engage the public to join the community-based network through anti-drug activities organized by anti-drug ambassadors. They are encouraged to design their own promotional activities for community members in the targeted districts.Types of activities can include but not limited to health talks, booths, outreaching activities, games, posters, leaflets and websites.
