It's a single tool in a box of tools towards recovery. I don't think it was meant to be the adrenaline rush that's meant to be helpful, but rather giving them an experience to hold on to, and to try and teach them to take control of their destiny. At least that's what the video says.

I'm also skeptical as to its benefits. But anything is better than locking addicts in a box and expecting them to be magically cured. In my experience, it's a lack of support networks and associating with the wrong people that keeps most people locked in a cycle of crime, addiction, and poverty. There are a lot of people who are "rehabilitated" and full of optimism, but then they go back home, to the same toxic environment and fall back into the same cycle.
