A.J.
I have an adult friend who was sent to an intense bootcamp as a kid. He's 35 now. He was caught smoking pot in middle school (maybe high school?) and general serious mischief. He went with a group of super bad inner city kids on some trek from Texas to up north..they went camping along the way and had to work really hard. It was military style with a dose of wilderness survival. He later served in the Marines several tours right after 9-11 fighting in Afghanistan. He's still a trouble maker/rebel/artist type. He said his behavior never really improved much. But it was the most enriching experience of his life. He said it make his military service easier, and he became the only non-racist kid in his local school due to the friendships formed with the inner city kids. He looks back on it as one of the best things he ever did. While he was still a mischief maker, it transformed his attitude and outlook on life and improved his confidence in his own abilities. It also taught him to respect-or at least show respect to-superiors. So I'd say it did a lot of good.
