It is not a secret. There is a lot of drug and alcohol abuse in our communities. How much? Nobody knows for sure. Certainly significantly less than the general community but still far too much. And even, רח"ל, amongst yeshiva boys. And not only the "bummy" boys - even some good yeshiva boys are big drinkers and drug users despite the fact that it is halachically forbidden. .
This is my question - Is anybody doing anything about it? Do Rabbeim know that their talmidim are using drugs? Do parents know? While on the topic - Do Rabbeim know how many boys are מוציא זרע לבטלה? Does anybody talk about it?
If there is no kedusha - there is no yesod. If there is no yesod then all of the Torah and mitzvos doesn't have the desired effect. Drugs, alcohol, הוצאת זרע לבטלה וכל אביזרייהו are ARCH ENEMIES of kedusha and yesod.
