With equal respect
From what I've heard, the illegal P&D networks are pretty pissed. Sales points? A shitty house in the alley behind a shitty house? Or stroll into a clean establishment with a waiting room with chairs you might, actually, you know, want to sit in?
Here's the thing: people get high, on one thing or another, and have, for all of the time we've been people. You'll not stop that through legislation or indignation.
It's up to you. It's called freedom to do with the only property you really ever own - your body.
