In case you missed it, see reasonably fair write up in The Telegraph.
The revealing bit was when RB was in a cafe interviewing too women who were full-on Category B drug users i.e. whose lives had been ruined by drugs and/or whose lives were ruined so they turned to drugs. Chicken and egg.
The first merrily admitted to still regularly using drugs, despite having been in prison and put on some mandatory, then RB chatted to the other one.
You could see the first one in the background of the shot, smoking a cigarette... outside the cafe.
There's this weird thing with smokers, me included, we are so terribly law-abiding and subservient when it comes to the smoking ban. For example, cheerfully admitting, on public TV that you take drugs, despite being known to The Authorities, but popping outside when you want a fag.
