Okay, good. Thank you.
I'll address Dr. de Villa again. You were talking about crack, that it is still an issue there. One of the things this reminded me of, as I've been watching the history of methamphetamine and this recent history, is that it sounds parallel with what happened with crack in the 1980s. Cocaine was a very expensive drug in the 1970s before crack was invented, and in the 1980s, crack was invented. I think it first surfaced in New York in 1980, and that's when it started to flood the streets and become a drug of those with low incomes and those living on the street.
You said actually that there's more cocaine around in your centre. What are the trends over the years? Would you say the use of crack is levelling off? Is it going up? Is it going down?
