Use of potentially abusive psychotropic substances in psychiatric inpatients

A series of 417 consecutively admitted psychiatric inpatients were studied with regard to their use of potentially abusive psychotropic substances in the last 3 months preceding admission. In all patients face-to-face interviews were performed; in 354 of them urine specimens could also be tested. Alcohol and benzodiazepines belonged to the most frequently used substances followed by cannabis, opiates and cocaine. Barbiturates, hallucinogens and amphetamine derivatives were only exceptionally reported. The most important finding of the study is that every fifth patient regularly used "hard” drugs (opiates and/or cocaine), every fourth patient illegal drugs and every third patient alcohol. Substances were found in 54% of all urine specimens; methadone, opiates and cocaine were hardly found alone. For the latter substances excellent agreement was found between interview reports and urine exams. Excluding patients diagnosed as substanceuse disorders, there were no statistically significant differences between schizophrenic, affective, neurotic/stress/ somatoform and other disorders with regard to the use of "hard” drugs and illegal drugs. Regular substance use correlated with much worse psychosocial adjustment. Substance use has to be explored and considered in every individual psychiatric inpatien
