YWN is reporting that rabbonim and roshei yeshiva in Lakewood have issued a "kol koreh", warning all yeshiva bochurim and baalei batim against the use, even occasional and recreational, or sale, even legal, of marijuana in Lakewood. 

Interestingly, the English translation adds the word "recreational" to the type of usage being banned, while the original in Hebrew says any type of usage whatsoever - that sounds like even medical usage should be banned, which does not really make sense. Maybe only recreational is what they meant to ban, but then the original Hebrew version is inaccurate.

So, if you are in Lakewood and want to use or sell marijuana, use it at your own risk. You might be chased out of the community or your kids thrown out of school for it.

The way it works though is that this ban is unlikely to succeed. People in Lakewood are as human as they are everywhere else. I am 100% sure there are already plenty of people in Lakewood using marijuana or its sub-products, with permission or not. Opening marijuana-based businesses might be more difficult as that is more public, but I am sure that with time that will happen as well, if it isn't already happening. it is just the way it is.
