But the good outweights the bad.
Usually someone already tried drugs/alchohol before going to Israel. In many cases, in fact, it is easier to avoid since they don’t know anyone at this crack sq. and would have to spend time being ‘vetted’.
There are many more cases of kids getting away from the connections to that they already have and getting inspired from being in Eretz Yisroel.
the other case of someone who never tried drugs/alchohol and then trying this in crack sq. is also less likely.
they wouldn’t know how to act in such a setting.
they would likely be introduced by a friend in the seminary or yeshiva (And/or).
This can happen but as you see, it’s a minority of cases.
THe ones who used D/A in their hometowns and then go to Israel with every intention of immediatly using, would have continued to use in their hometowns anyway.
The issue is recovery and theauputic programs to offer them alternatives to drug/alchohol use/abuse.
