I believe harsh aversion therapy using chemicals and electricity has all but completely fallen out of favor. But it’s worth mentioning that talk therapy as conversion therapy is linked to high rates of severe depression and suicidal ideation. Harsh aversion therapy on unwilling adolescent subjects has always provoked strong opposition, and for obvious reasons, but people should be aware that adolescents who go into conversion therapy willingly are more at risk for mental health problems than those who just go along because they have to.
