Review: scheduling drugs and national legal controls the need for research

The system of scheduling narcotic drugs and psychotropic substances under national legislation does not always correspond to the system of scheduling under the international drug control treaties. Even though many drugs have been scheduled under the international drug control treaties, few studies have been done to identify what happens when drugs are scheduled at the national level. Preliminary studies seem to indicate that non-availability and higher prices are two problems which are associated with the scheduling process at the national level. Further research is needed to have a better understanding of the dynamics of the scheduling process and the impact of national controls.
