'Mind-altering practices are used'
My church did not use any method like this that I recall. At home was a different story though.
I was drugged almost every night for months because I was having trouble sleeping. I had an extremely early bedtime so I wasn't tired, and what kid wants to go to bed anyway. I was also having recurring nightmares about going to hell. A month or so into the drugging, I started having hallucinations every night.
My parents didn't believe I was hallucinating so they kept the dosing up for months. Finally once they stopped, the hallucinations stopped. They did say (in front of me) that they were happy I was so terrified for my future, and that the nightmares and hallucinations would help keep me scared straight.
