Given all this, do you think it's worth organizing separate lessons in schools designed to tell children about gambling addiction? That is, to tell children about gambling addiction separately from addiction in general - alcohol and drug addiction.
Why not?? As long as the content of the lesson is suitable for the school kids, that should be fine! Education about such things are very much needed, even the alchohol and drug addiction can be added in the curriculum. Also live awareness workshop is a very effective way to teach kids about bad addictions.
Gambling addiction is indeed a psychological issue. But if the awareness is created at a young and tender age, that may become fruitful at later stages of life.
