ABSTRACT
Substance abuse is defined as a pathological use of alcohol or drugs, characterized by daily
intoxication, inability to reduce consumption, and impairment in social or occupational
functioning. Cannabis is one of the most commonly used recreational drugs among
adolescents. Though cannabis was being used in India for over centuries for medicinal and
recreational purposes, it is now one of the widely abused drugs of choice among the youth.
Various researchers have contradictory views on neuropsychological effects of cannabis.
With the objective of understanding the ability to inhibit cognitive interference among
adolescents with cannabis use disorder the current study has selected 20 adolescent cannabis
users and healthy participants each. The participants were matched by age and screened for
individuals who met the inclusion/exclusion criteria of the study. The ability to retain visual
stimulus was assessed using Benton Visual retention test and the ability to inhibit cognitive
interference was assessed using Stroop Test. Findings reveal that there is significant
difference in visual retention ability among cannabis users after a period of brief abstinence
in comparison to healthy adolescents whereas no significant difference was observed in
inhibition of cognitive interference among both the groups.

It is a known fact that exposure to illicit and legal drugs is harmful to the brain. Developing
brain is susceptible to the effects of drug and its abuse. Biological processes that ideally
contribute in the development of executive function of the brain tend to be compromised due
to exposure of illicit drug use during adolescence (Rosner, 2013).
Addiction is a chronic disease of brain that interferes with the reward, motivation, memory
and related circuits of the brain Dysfunction in these circuits leads to characteristic biological,
psychological, social and spiritual manifestations. This is reflected in an individual’s
pathologically pursuing reward and/or relief by substance use and other behaviours
(American Society of Addiction Medicine, 2011).
