“Problem, intensive drug use and polydrug use”Introduction Danica Klempova, Scientific Committee meeting, Lisbon, 17 November
The traditional Problem drug use key indicator • To look at the most harmful, heavy forms of drug use • Traditionally using indirect statistical methods (multipiers, CRC, MIM) to estimate the sizes of these – largely hidden – populations • To assess needs and coverage of interventions • Defined by (umbrella definition) • drug-type (opioids, cocaine and amphetamines) • and a broadly described behavioural pattern (injecting and/or long-term and/or regular) • NOT BY PROBLEMS!
Changes in the drug situation and reaction to them • Changing patterns of drug use in the past 15 years (stimulants, cannabis TDI) • 2004 focused small expert meeting in Sintra • Reporting by drug (POU, PSU) and IDU - overlapping categories • Applying instruments within general population surveys (cannabis abuse and dependence)
Discussions about concepts… • Traditional PDU – trends uninterrupted • Intensive, frequent, long-term, dependent, harmful, abuse…(by drug and pattern of use) • Polydrug use yes, but what kind (+question of alcohol) • Substitution medication – distinguished
…have to be closely related to data sources • Traditional data sources for the indirect estimates; improvement of data quality • Novel data sources for indirect estimates (e.g. emergency room data, …) • Out-of-treatment populations – focused studies in different settings (street, LTS, ..) – e.g. RDS • General population surveys for cannabis intensive/long-term/dependent use (other substances with high prevalence and lower stigmatisation of use)
