I'm not a fan of one Mr. A. Crowley - but at the same time, in his novel "Diary Of A Drug Fiend" Crowley had many wonderful ideas to present, and one of them concerned "finding yourself."
The drug addicts, being rescued by "King Magnus" who was actually supposed to represent Crowley, the Satanist. . . .were relocated to a remote island away from all possible chemicals.
After fits and screaming and sickness of withdrawal - the minds of the two drug addicts started to return to normal, and focus on what they were meant to focus on.
The fighter pilot/coke and heroin addict started building things, he was a natural builder and engineer.. .. . so forth,so on.
I hope this was somewhat helpful.
