The Association of Parental Monitoring with Substance Use in Thai Adolescents and the Moderating Effect of Anxiety
Based on data from 5,661 Thai adolescents, this study found that parental monitoring significantly reduces the likelihood of smoking and marijuana use but does not affect amphetamine use, while anxiety was not found to moderate these associations.

Imagine the teenage years as a high-stakes video game level where the rules are fuzzy, the obstacles are tricky, and the temptation to try "alternative methods" is everywhere. In the real world, these alternative methods often look like smoking, marijuana, or other drugs. Scientists who study this are like game designers trying to figure out why some players stay in the game healthy while others get stuck in a bad loop. Two big ideas help them understand the game: Parental Monitoring, which is basically how well a parent keeps an eye on what their kid is up to when they aren't in class (like knowing who they are hanging out with or where they are), and Anxiety, which is that heavy, worried feeling in your stomach that sometimes makes you want to do something risky just to feel better. The big question researchers have always asked is: Does having a parent who knows your schedule actually stop you from using drugs? And if you are already feeling super anxious, does that parent's watchful eye stop working?
This paper is like a detective story set in Thailand, where researchers looked at data from over 5,600 students aged 13 to 17 to answer those questions. They treated the students' lives like a giant dataset, checking if the "parental radar" was on or off, and then seeing if the kids were smoking, using marijuana, or trying amphetamines. They also checked if the students were feeling anxious, wondering if worry might act like a shield that blocks the parent's influence.
Here is what the investigation found. First, the "parental radar" is a powerful tool. When parents knew what their kids were doing with their free time, the odds of those kids currently smoking dropped significantly. It's as if the parent's awareness acts like a security system that makes it harder to sneak a cigarette past the front door. Specifically, the study found that adolescents with involved parents were much less likely to be current smokers (the odds were about 0.67 times lower) and much less likely to be current marijuana users (the odds were about 0.60 times lower).
However, the story gets a little more complicated with amphetamines. While parents' awareness helped with smoking and marijuana, it didn't seem to make a statistically significant difference for lifetime amphetamine use. The researchers suggest this might be because amphetamine use is still highly illegal and stigmatized in Thailand, so kids might be hiding it better, or perhaps the "lifetime" question (asking if they ever tried it) captures past behavior that doesn't match up with what parents know right now.
The researchers also tested their second big idea: Does anxiety break the parent's security system? They wondered if a kid who is super worried might ignore their parents' rules anyway, making the monitoring useless. The answer they found was a bit surprising: No. The study found no evidence that anxiety changes how well parental monitoring works. Whether a student was feeling anxious or not, having a parent who knew their activities was still a protective factor against smoking and marijuana. It's like saying the security system works just as well whether the house is quiet or stormy; the anxiety didn't turn off the alarm.
The study also spotted some clear patterns in who was using what. Boys were more likely to use these substances than girls, and interestingly, the study found that for marijuana and amphetamines, the younger teens in the group were actually showing different usage patterns than the older ones, which is a twist compared to some other studies.
In the end, this paper suggests that keeping an open line of communication and knowing what your teenager is up to is a solid defense against smoking and marijuana use, even if they are feeling stressed. It doesn't solve the whole mystery of drug use, and it doesn't seem to stop amphetamine use in the same way, but it confirms that parents aren't powerless. The authors conclude that while we need to learn more about the different ways parents can guide their kids, the simple act of knowing what your child is doing remains a strong shield in the chaotic game of growing up.
