Hi, Matt. I don’t know, but you can e-mail Takiwasi and they will surely answer that. There is a group in Brazil, São Paulo, doing a similar work with homeless people addicted to crack and alcohol. I read an article and I thought to be very interesting the process they use. I am passing on the link and Goggle translation tool can help converting to English [not the ideal, but it surprised me the first time I used it]. I might translate it myself later on, I just don’t have time right now.
