Abstract

Background: Using multiple substances carries higher risks and health consequences than using a single substance. This study aims to identify polysubstance user subgroups among vocational students in northern Thailand and evaluate associated risk factors by gender.

Methods: This study was conducted among Thai vocational students. Latent class analysis (LCA) was utilized to identify classes of polysubstance use.

Results: The questionnaire was completed by 2399 male and 1213 female respondents. LCA revealed distinct patterns of polysubstance use between male and female adolescents. A four-class solution was the best-fitting model for males: class 1 (1.42%) was characterized as the polysubstance user (all types) group; class 2 (22.23%) included the predominant alcohol and tobacco user group; class 3 (5.37%) formed the predominant alcohol, tobacco, cannabis, and kratom user group; and class 4 (70.98%) comprised the nonuser group. For females, a three-class solution was the best fit: class 1 (1.55%) included the polysubstance user (all types) group; class 2 (80.94%) comprised the nonuser group; and class 3 (17.51%) represented the predominant alcohol and tobacco user group. Factors that significantly increased the risk of polysubstance use among both male and female adolescents (p < 0.05) were positive attitudes toward polysubstance use and tobacco or cannabis as their first substance used.

Conclusion: Thailand should enforce existing legislation strictly and effectively to limit youth access to tobacco. It is important to provide medical information about the negative health effects of recreational cannabis use.
