    during the reference period
  – Common reference populations:
     • General population: 15-64 years
     • Youth population: 15-24 years
Prevalence
of drugs (2)

• Prevalence is expressed as a
  percentage of the reference
  population
• Standard prevalence measures relate
  to reference period:
  – Lifetime prevalence (“ever use”)
  – Last 12 months’ prevalence (“recent use”, “use
    in reporting year”)
  – Last 30 days’ prevalence (“current use”)
Severe drug abuse
(problem drug use)

• Problematic or chronic drug use or
  drug users in need of help from the
  perspective of the reporting country:

  – Applies only when a country differentiates
