Yes I think they could be , the constant sniffing with Jason is a give away Danielle W used do it too , that would explain why they are quite erratic especially Paul and they seem to struggle because they could be spending on drugs ??and that doesn't come cheapI just watched the live video where Jason says he washes his hair once a month and Paul laughs like he thinks it's cute or something. He probably doesn't want Jason wasting any of their precious pennies on luxuries like shampoo.
I don't know about this ,just a theory but what do you guys think of the idea of them being on drugs? I mean the sniffing, the dark eyes, Paul's mood swings, could be possible
