  Purpose

The aim of this study is to get new information on the whole blood-plasma-oral fluid ratios of psychoactive drugs which are encountered in traffic.

Samples are taken from drivers suspected of being under the influence of drugs or medicines. The samples are analysed with immunological methods and GC-MS.

Observations from Police and a physician on impairment are combined with the results of the different bodily fluids. Observational evaluations and substance concentrations are compared.


Condition
Driving Under the Influence

Study Type: Observational
Study Design: Observational Model: Case Control
Official Title: DRUID Sub-study: Substance Concentration Ratio/Impairment

Further study details as provided by National Institute for Health and Welfare, Finland:

Primary Outcome Measures:
  • ratio of psychoactive drugs/medicines in whole blood-plasma-saliva and correlation to symptoms of impairment [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • prevalence of psychoactive substances in the general driving population [ Time Frame: three years ]

Biospecimen Retention:   Samples With DNA
Blood samples and oral fluid are collected for the study. However no DNA detection is done at any stage. The laboratory where samples are analysed do not analyse DNA. DNA is not relevant to this study.

Enrollment: 300
Study Start Date: May 2008
Study Completion Date: October 2011
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts
