[Evidence of a modification of the profile of addictive drugs consumption through the study of patients consulting a psychiatric emergency room].

The consumption of psychoactive drugs is frequently the reason of consultation in a psychiatric emergency unit. We present here the evolution over time of the consumption pattern of patients consulting the psychiatric emergency unit of the Brugmann University Hospital. Major modifications were observed during this period. Mainly, problematic consumption of opiates was progressively overwhelmed by this of cannabis, psychostimulants and recently synthesis drugs. We suggest that this reflects the situation of psychoactive drugs consumption in the general population. This implicates a modification of prevention and treatment attitudes in drug consuming persons.
