Based on the findings, except for substance use that it has already been made in 2006, macrolevel social policy regarding social harms seems necessary to be built. Just by taking a macro-level policy, it will be possible to design pathways for social harms not to disturb social security. To reach social policies which fits for social harms decline, so that social security become provided, adequate macro level policies must be adopted to avoid arbitrary decision making, to get all capacities, either in GO or NGO parts together, to begin an inter-organizational coordination, to manage sources in an effective way, to determine priorities for policy making, to administer programs comprehensively, inclusively, and adequately, and finally, to do a better work division among related organizations in different levels, and finally, social security become promoted.
