Drug abuse affects all sectors of society and countries at all levels of development.
Therefore drug demand reduction policies and programmes should address all sectors of society. A rapidly changing social and economic climate, coupled with increased availability and promotion of drugs and the demand for them, have contributed to the increasing magnitude of the global drug abuse problem. The complexity of the problem has been compounded by changing patterns of drug abuse, supply and distribution. Extensive efforts have been and continue to be made by Governments at all levels to suppress the illicit production, trafficking and distribution of drugs. The most effective approach towards the drug problem consists of a comprehensive, balanced and coordinated approach, encompassing supply control and demand reduction reinforcing each other, together with the appropriate application of the principle of shared responsibility.
