I think instead of focusing on gambling addiction, schools should have like a mandatory subject talking about the dangers of any kind of addiction which teaches them to do things in moderation.

Having a designated subject primarily for gambling addiction only can be both a boon and a bane- it can be a boon where it can teach students to be more careful with their decision into not trying gambling at all; and it can be a bane when curiosity sparks with these students for them to try it.

In conclusion, I highly recommend that in the early levels of education, students are being educated on the dangers of being addicted to a certain activity so that it can be an all encompassing lesson that applies to every addiction.
