Abstract
OBJECTIVES
To examine the prevalence of substance use among treatment naïve patients with first episode psychosis presenting to a psychiatry outpatient clinic in India.
METHODS
The study sample consisted of 139 first episode treatment naïve patients with psychosis from in and around Bangalore, a city in South India. Self as well as informant-reported data on type, use and duration of substance use as well as the severity of psychotic symptoms were collected using structured instruments. Urine toxicology screen was also conducted for six common drugs of abuse. Breath alcohol analysis was performed in all patients.
RESULTS
Acute and transient psychosis was the most common diagnosis (42.4%). Overall, 20% of the population reported current substance use disorder (excluding nicotine). Current alcohol dependence was diagnosed among 17.3%, whereas cannabis dependence in 3.6%. Life time as well as current use of cannabis was less than 6%. While one patient reported inhalant abuse none reported use of amphetamine or opioids. There was very high concordance between reported drug use and urine toxicology screen.
CONCLUSION
The use of illicit drugs is substantially less among first episode drug naïve patients with psychosis in an Indian urban clinical setting compared to rates reported from developed countries like North America, Canada and UK.
