This is regularly deprived for the mentally ill.
Either humans have this right or don't.
Either humans have this right or don't.
schizophrenics often reject medication in the midst of psychosis, while agreeing it's necessary when they're lucid.
lots of addicts genuinely want to kick the habit, but their willpower fails them. drugs like disulfiram and naltrexone can help by making highs unpleasant or unattainable.
sex offenders who abuse minors are sometimes chemically castrated with GnRH agonists as part of their parole. this reduces their sex drive by depriving them of androgens, reducing the risk they'll reoffend.
where to draw the line is complicated, but at least in the schizophrenic case I really think forced medication compliance helps everyone. if you're not lucid you aren't competent to make medical decisions.
Anyway. This moment is a _very_ direct test of this question. Answering it, or more carefully, your emotional reaction on reading this, will expose some of your absolutes.
my rule of thumb is that if the patient, after being returned to lucidity by meds, agrees in retrospect that meds were necessary, then it's the right call.
the other exception is if the person is at substantial risk of hurting others if unmedicated. then the violence of mandated medication is warranted.
barring that, if someone on psych meds wants to go back off them, I wouldn't prevent them from doing so.
