Using the KYRBS, we developed a predictive model to extrapolate the behavioral patterns of Korean adolescents regarding substance use. Due to rigorous substance regulations and law enforcement measures in South Korea, accessibility and consumption of substances are notably limited [18]. Consequently, the number of instances representing substance use within the KYRBS was sparse (n=12,803, 1.17%).

The decrease in reflexes and planned choices associated with substance use may also lead to risky sexual intercourse [10,11]. Traceability studies on the transmission of HIV/AIDS have found that the paths of HIV infection and transmission among users of new types of drugs are mostly high-risk sexual behaviors after drug use [12].

We adapted a measure of resistance skills from a previous evaluation of the keepin’ it REAL substance use prevention program for elementary and middle school students [25]. In the current study, students rated the extent to which they engaged in different behaviors when they do something (eg, think carefully about their choices). We recoded items so that higher scores indicated more thoughtful or less impulsive decision-making (1 = Strongly Disagree, 4 = Strongly Agree).

This includes the use or distribution of FTS and XTS, which indicate the presence of fentanyl or xylazine, respectively, as well as Fourier-transform infrared spectroscopy (FTIR), which can identify all the chemicals in a substance in proportion to the total sample (eg, what percentage of a checked sample is fentanyl and what percentage is xylazine).

In 2021 alone, over 1 in 5 adolescents aged 12-17 years misused substances (illicit drugs and alcohol or tobacco products) [2] and 2 million adolescents had a substance use disorder [2]. Adolescent substance misuse, defined as “the unhealthy use of alcohol or drugs to relieve stress, alter reality or bring about pleasure” [3], increases the risk of developing a substance use disorder.

Prospective studies have shown that at the beginning of treatment for FEP, cannabis is the most frequently abused drug (~50%); about 3 times more participants with a comorbid substance use disorder (including CUD) are male (78%-86%) than female and that persistent cannabis use is associated with poor clinical and functional outcomes [10-15].

More than 275 million people worldwide used substances in 2021, with problematic substance use costing the lives of half a million people globally in 2019 [1], an increase of more than 20% in the past 10 years. Further, substance use often has far-reaching consequences on human health and well-being, resulting in the loss of 18 million years of healthy life [1].

Together, these findings demonstrate the large variety of substance-related topics discussed on social media sites, which can be a source of data for substance use research, and the complexities of the discussions, which are dependent on the substance mentioned and the perspective of the poster.
