i saw this post and i just had to say something. being a 15 year old kid myself, my opinion might not be as valued as these parents on the board but i think you should definatly understand and allow him to smoke (because hes gona blaze no matter what, its better you guys have some kind of agreement and that you know he does it in a safe place etc.) freely since you said that originally you didnt have much of a problem with it.

cannabis is also, in my opinion, the number one bonding method. if you and your son share a spliff or something, or even just allow him to blaze in his room, then cook up a big pie or something for his muncies lol, im sure youll be amazed at how much closer youll be. trust and being able to tell your parents anything is so important.

however, if you decide that having a talk with him that his grades are going to continue to drop no matter what (100% his decision) that he cant smoke anymore, he will simply rebel and find himself sneaking around, hiding his smoking stuff from you, and being overall much more stressed out and hormonal.

just my 2 cents, im sure it will all work itself out, most people dont smoke cannabis their whole lifes. good luck polaris, you sound like a good mom lol.
