Pattern of Psychoactive Substance Use in Sierra Leone: A Descriptive Retrospective Study

Background Substance use, and pattern of consumption varies across population and may, within a particular population, show temporal variations in accordance with changing fads. Understanding the pattern of substance use in a population is key to any programme of demand reduction. Thus, we studied a consecutive series of patients with substance use disorders in our facility, aiming to determine the patient profile and pattern of substance use. Methods Hospital’s digital register was consulted and data of patients who were seen over a 16-months period, and who had diagnosis of ‘alcohol and substance use disorder’ were retrieved and analyzed. Results Seven hundred and nineteen patients were treated for substance use disorder over a 16-months period. Age of patients ranged from 16 to 69 years with mean age (SD) of 28.7(9.2) years. Majority were males (91%), single (87%) and had been to secondary or tertiary school with or without graduation. Fifty nine percent (421/719) of the patients admitted being on ‘Kush’, 49% on alcohol, 47% on cannabis, 11% on tramadol and 5.6% on cocaine. About 71% of the patients were poly-substance users while 29 percent were on one agent. Alcohol, ‘Kush’ and cannabis were the most common preferences of those who use more than one agent. Conclusions Substance use disorder in Freetown was most prevalent in young, adult, secondary school educated males. ‘Kush’ was the most common agent of abuse and frequency of polysubstance use is high. Understanding the factors responsible for low substance use among females in the population might point to some preventive control measures.
