Everybody will go through this phase. Our parents did, we did, and for sure our kids will.
It depends on individuals if they want to try it or not.
If it stays as the title suggests, recreational, I see no harm in it.
The problem is we are different individuals, and some of us are more prone to addiction than others.
It is true that everyone will go through this phase,
but not everyone (generation) children will try it,
it depends how where parents educate and control his son
