Knowledge, Attitude, and Expectancies Related to Cannabis Use: A Cross-sectional Community Study Among College Students from Bangalore, Karnataka.

Background: Cannabis use among youth is increasing; this study aimed to assess college students' knowledge, attitude, and expectancies toward cannabis use.

Methods: Cross-sectional survey using standardized tools among undergraduate and postgraduate college students in urban Bangalore, India ( = 405).

Results: Ten percent reported past three-month cannabis use, with 1% reporting daily use. Users were significantly older (median age 21, IQR 22,20 [vs. 20, IQR 21,19], < .001) and belonged to families with higher monthly incomes ( = .02). Use was significantly higher among males than females (65.9% vs. 34.1%, = .006) and postgraduate students than undergraduates (51.2% vs. 48%, = .001). Users were also significantly more favorable toward cannabis use (median score 4, IQR 6,2 [vs. median 3, IQR 4,2], = .005) and had more positive expectancies from use (median score 2, IQR 3,2 [vs. median 2, IQR 2,0], = .001). Nearly 30% were unaware that cannabis can affect a person's ability to drive safely or that it can affect executive functions, including academic performance. Over one-third were unaware of the current legal status of cannabis in India. Overall, 36%, 25%, and 17%, respectively, said that cannabis use is safe when used for recreational purposes, cannabis should be legalized as it helps to relieve stress, and cannabis use among youngsters should be acceptable in society as it is "part of college life."

Conclusion: Findings build on existing literature on cannabis use among college youth in India, which can guide preventive interventions and policies for this vulnerable group.
