Street sellers get their supply from people up the food chain who are savvy enough to use SR. I've not sure who you think the sellers on SR are, but they weren't mom and pops. As for the buyers, yes most likely white collar addicts.

I've never done drugs in my life, but most drug users using SR were not addicts. They were just drug users.

I would think up the food chain deals would not have taken place on the street in the first place. More replacing the house level deal with SR.
