Psychotropic Substances Research Group

You are here:

Psychotropic substances are commonly used as psychopharmaceutical agents for treatment of psychiatric disorders. On the other hand, psychotropic substances are used by humans in order to induce non-ordinary states of consciousness. Therefore, they are important instruments for investigating different aspects of human consciousness. Moreover, psychotropic substances are associated with substance-related disorders, including dependence or drug-induced psychoses. In addition, psychotropic substances can influence course of psychiatric disorders (e.g. increase of symptoms).

Our research group investigates different aspects of psychotropic substances with a special focus on illegalized:

  • Effect of psychotropic substances on specific functions of consciousness in the framework of experimental – behavioural and imaging studies
  • Psychotropic substances in the context of recreational use – patterns of substance use, prevalence and motives of use and new psychoactive substances
  • The effects of drug policies on use, user health and treatment
  • Preventive interventions in all fields of drug use
  • Epidemiology, treatment and prevention of substance-related dependence
  • The clinical use of psychotropic substances as psychopharmaceutical agents, especially the use of approved drugs in new indication or forms of application
  • Psychosis and comorbid substance-related dependence ("double diagnoses")
  • Medical and psychosocial problems as as consequences of psychotropic substances
  • Specific aspects of substance use in the elderly (Co-operation with the working group for geriatric psychiatry
  • Anthropological, historical and sociological aspects of psychotropic substances
