you are missing one type of addiction, that is online gaming, there have been many cases in my place where school children have skipped school just to play games in internet cafes and also bet online sports (fantasy sports) there
Whatever it is, the so-called addiction will surely lead everyone to stupid things, such as cheating and the most reckless thing is robbing
I'm sure several countries also have similar cases where many school children play truant just to go to internet cafes and play online games or play gambling games.
Many school children in my country do the same but the majority here prefer to play poker from local poker apps that have fiat basis.
But sometimes there is also control carried out by the authorities and then handing over the children to their parents.
This is the beginning of the breakdown of today's young generation because they cannot think properly for every activity that is carried out.
that's how the current younger generation seems to not only apply in your country but also applies in my country, most of them start corrupt practices where their school payment money is used to play gambling so they have to lie to their parents that school payments have not been paid, this often happens in my country too because they are like addicted to gambling and end up doing things that are not good for minors to do.
It is important to teach children to stay away from gambling because of course their emotions have not really been controlled properly so it takes time to make them realize that when they eventually grow up they will regret their actions when they were young, so there will not be a good effect on their underage gambling other than committing corruption money to pay for school and skipping school.
