You are just wrong about this one HW... sorry... It is 100% clear that Randy has issues that go far deeper than weed... it is clearly a coping mechanism for him... His father went to Northwestern... If you listen to Randy... he is not a dumb individual... He needs help.
I don't disagree with you.
It's mental and emotional. Apparently he's been offered plenty of help, but ultimately, only Randy can accept it.
