To support Governments to adequately estimate and assess their needs for internationally controlled substances, three e-learning modules were developed for use of competent national authorities:

  • Estimates System for Narcotic Drugs
  • Assessment System for Psychotropic Substances
  • Estimates of Annual Legitimate Requirements (ALRs) for Imports of Precursors of Amphetamine-Type Stimulants

The modules are free of charge and available upon request to staff members of competent national authorities. Requests for access can be sent to

Successful completion of the e-learning modules will be acknowledged with an online certificate. The modules are currently available in English. Translation into other UN official languages is dependent on the availability of extrabudgetary contributions.

The INCB e-learning modules aim at assisting Governments in building capacity and institutional knowledge. The Board welcomes any comments or feedback about the modules.
