To build a healthy community without drugs requires the joint effort by various professions. It is desirable that our professional colleagues can be sensitive to the ‘social determinants of health’ and identify what conditions of individuals, families, schools and communities can affect health behaviours. They should also understand how they can let their service targets and the public realise drug scourge and the proper use of drugs. This facilitates us to help targets, based on their age, ethnicity, social/economic background, situation, ability and characteristics, to manage their health. We can also reinforce their motivation and habits in developing a healthy lifestyle. When they become healthier physically and mentally, the risks of taking narcotics, drug abuse and having other health issues can be minimised. Therefore, CDAC has launched ability-building training and exchange activities for teachers and staffs in primary and secondary schools, social workers, medical professionals and post-secondary students in related disciplines.
